Compendium of Bivalves 2. A full-color guide to the remaining seven families. A systematic listing of 8'500 bivalve species and 10'500 synonyms
Abstract
This book completes "Compendium of Bivalves, Volume 1" published in 2010. It adds the 7 families (Thyasiridae, Lucinidae, Galeommatidae, Tellinidae, Cyrenidae, Ungulinidae, Teredinidae) missing from volume 1. It contains major additions and rectifications to the families treated in 2010. It completes the tabulation of biodiversity and biogeography of global Bivalvia. The book now contains the data and synonyms of all marine and brackish water bivalves recognized by the author. Overall 8'500 valid species and 10'500 additional synonymous names are systematically listed with all data currently available. Altogether 45 new species, 33 new genera, 6 new subfamilies and 1 new family are proposed within this book.

... Вместе с тем, по данным Ю. Вана с соавт. [Wang et al., 2021], некоторые представители подсемейства Chioninae Frizzel, 1936(Anomalocardia producta Kuroda et Habe, 1951 входят в одну кладу и имеют близкое сходство с Macridiscus; однако М. Хубер [Huber, 2010[Huber, , 2015 отнес этот вид к роду Cryptonema Jukes-Brown, 1914 и подсемейству Tapetinae. Раковина Meretricinae характеризуется следующими признаками: треугольная, почти равносторонняя, скульптура слабая или отсутствует, имеются передние латеральные зубы (два в правой створке и один в левой створке), тогда как у Tapetinae раковина гладкая или концентрически скульптированная, реже с радиальными и концентрическими ребрами, латеральных зубов нет, ширина замочной площадки обычно узкая [Невесская и др., 2013;Coan et al., 2000;Mikkelsen et al., 2006]. ...

A young specimen of Macridiscus melanaegis (Römer, 1860) (Bivalvia: Veneridae), a new species for the fauna of Russia, was found in the southwestern part of Peter the Great Bay (Sea of Japan), near the Russian-North Korean border. A description of the shell, comments, and illustrations are given. This species can be considered as a potential invasive species in the Russian waters, which may be facilitated by the ongoing warming of the coastal waters of the northwestern part of the Sea of Japan.
... Members are recorded from the Late Cretaceous onward (Chavan, 1962(Chavan, , 1969Moore, 1988;Coan & Valentich-Scott, 2012). Recently, Huber (2015) recognized 100 Recent species grouped into 16 genera (including three new genera) in the world. Among them, 23 species belonging to seven genera have been found in the Northwest Pacific (e.g., Scarlato, 1981;Higo et al., 1999;Xu, 2012;Lutaenko & Noseworthy, 2012). ...
... The generic classification of the family Ungulinidae is controversial (e.g., Dall, 1899;Lamy, 1921;Chavan, 1962Chavan, , 1969Habe, 1977;Coan et al., 2000;Coan & Valentich-Scott, 2012;Nevesskaja et al., 2013;Huber, 2015). I herein follow the classification by Huber (2015). ...

A new ungulinid bivalve species, Transkeia sagaensis n. sp, is described from the uppermost Eocene-lowest Oligocene Kishima Formation in Kyūshū, southwestern Japan. The present new species is the oldest member in the genus Transkeia Huber, 2015. In the previous molluscan studies of the formation, no ungulinid species have been recognized. This is probably due to the misidentification to a venerid, Cyclinella? compressa (Nagao, 1928b).
... Coan et al. (2000) and Coan & Valentich-Scott (2012) considered Thyasira barbarensis (Dall, 1890) and possibly T. tokunagai to be synonyms of the North Atlantic species T. flexuosa. Huber (2015) claimed that T. gouldii and T. flexuosa from Primoriye should be identified as T. barbarensis, originally described from Santa Barbara Island (276 fathoms in depth) in California. Moreover, according to him, T. tokunagai is endemic to Japan, living in shallower water than T. barbarensis. ...
... Most Japanese malacologists treated Philis as a subgenus of Thyasira (e.g., Habe, 1951Habe, , 1977Higo et al., 1999;Okutani, 2017). However, Huber (2015) stressed the existence of a distinct "chondrophore" beneath the umbo and separated Philis as a genus from Thyasira. Although some Thyasira species has also a small node or "pseudoteeth" beneath the umbo as in T. tokunagai (Fig. 6A), based on our SEM observation, we follow the Huber's opinion and separate Philis as an independent genus. ...
... Among these, Thyasira inadai n. sp. is in the upper sublittoral depth to upper bathyal depth (11-1,075 m) of the Japan Sea, Bohai Bay and Yellow Sea and has not been found on the Pacific side (see above). On the other hand, the smaller species T. tokunagai is endemic to the Japanese region, as stated by Huber (2015). It has been recorded from the sublittoral to uppermost bathyal depth (3-250 m) in the Japan Sea and Pacific Ocean around Japan, and Japan Sea side of Korea (Kuroda et al., 1971;Ito et al., 1986;Min et al., 2004;Lutaenko & Noseworthy, 2012;Lutaenko, 2014;Lutaenko et al., 2021). ...
A new thyasirid bivalve, Thyasira inadai n. sp., is described from the Japan Sea. This species lives in the Japan Sea and Yellow Sea and can be separated from the relatively shallower-water dwelling T. tokunagai Kuroda & Habe, 1951 by having a larger shell, a long and narrow auricle, a medial flattened area, an excavated lunule demarcated by an incision, a narrow apical angle and a larger prodissoconch. Based on the size of the prodissoconch and on molecular data, T. inadai n. sp. is related to the north Atlantic species, T. gouldii (Philippi, 1845). This phylogenic relationship is likely due to migration through the Bering Strait, which has opened since the latest Miocene.
... "Said to inhabit canals" Remarks The number of specimens provided by Cantor was not noted in Benson's original description, although he later stated that only dead shells had been collected(Benson, 1855a: 138). Sanguinolaria iridescens has recently been designated as the type species of the new genus IridonaHuber, Langleit & Kreipl, 2015. Iridona iridescens lives in East China but its broader distribution is unclear due to confusion with similar species(Huber et al., 2015: 629).Genus Novaculina Benson, 1830Novaculina gangetica Benson, 1830"Anodonta ? ...
... Villorita) is in urgent need of revision. 74 The generic use of Iridona Huber, Langleit & Kreipl, 2015 with I. iridescens as its type species follows Huber et al. (2015). 75 Novaculininae has recently been synonymized with Pharellinae (Bolotov et al., 2018b). ...

... The family Mytilidae Rafinesque, 1815 is a cosmopolitan group, worldwide distributed (Bernard et al., 1993;Coan et al., 2000;Coan & Valentich-Scott, 2012;Von Cosel & Gofas, 2019;Huber 2010Huber , 2015Rios, 2009;Valentich-Scott et al., 2020) with more than 300 valid species (MolluscaBase, 2022). This is a diverse group adapted from shallow to deep waters. ...
... Kleemann & Maestrati (2012) redefined again Leiosolenus as a subgenus of Lithophaga recognizing that generic separation was still confusing. Despite this, Huber (2015) continued treating Leiosolenus as a valid genus based on genetic analysis made by different authors (Owada, 2007;Liu et al., 2018;Audino et al., 2020). ...
... The suggested subgenera included within Leiosolenus are not definitive. Huber (2015) recognized the subgenera Leiosolenus s. s., Diberus Dall (1898), Labis Dall (1916), Myoforceps P. Fischer (1886Fischer ( in 1880Fischer ( -1887 and Stumpiella Soot-Ryen (1955) based on the pattern of calcareous depositions that cover shell´s surface. The biodiversity of boring Mytilidae was widely studied and their shell morphology was defined by Owada (2007) as lithophagiform based on the relation of different measures, such as length, height, width and vectors related to the byssal retractor muscles. ...
The taxonomic status and anatomy of Leiosolenus (Labis) patagonicus (d'Orbigny, 1846 in 1834-1847) has been revised. This boring bivalve, belonging to the family Mytilidae, is the only Lithophaginae species distributed along the Argentinean coast. None of the fossil species mentioned for this area must be considered as a synonym of d'Orbigny´s species. Leiosolenus patagonicus is characterized by a thin shell, longitudinally elongated, with subterminal umbos and commarginal striae. The calcareous depositions on the outer surface of the shell are extended beyond the posterior margin. This species has well developed purple siphons, well differentiated morphologically from each other. Incurrent siphon is wider than excurrent, opened at the ventral edge and provided with a basal siphon valve at the base. Two pairs of demibranchs type B (1) from Atkins were observed. The shell characters and internal morphology were compared with other related species of the genus living along the South American coast. Finally, repository, type locality and habitat conditions were informed.
... The functional outgroup chosen for rooting was We chose to apply a conservative taxonomic composition of Eurytellina, Merisca, Scissula, and Angulus. Huber and Schniebs (2009) and Huber et al. (2015) recently carried out a series of new taxonomic allocations, creating some new genera and revalidating senior synonyms, which altered the traditional scenario of tellinid taxonomy. Despite their argumentation, the concept of some species and genera should be viewed with caution. ...
... madagascariensis, based on the general shell outline and ornamentation (Boss, 1969). Huber and Schniebs (2009) and Huber et al. (2015) considered it to only include T. albinella, while T. alfredensis and T. madagascariensis were assigned to Pallidea and Peronaea, respectively. However, Huber et al. (2015) argued that "Pallidea" alfredensis is close to Eurytellina, sharing the "weaker left dentition" within the suprageneric Eurytellina-group. ...

By contrast, Tellinota and Peronaea are in the "Peronaea" group, characterized by similarities such as the more developed calcareous layer of the ligament. ...
One of the main questions of phylogenetic systematics has recently focused on the reliability and robustness of taxonomic
data. Many recent studies are devoted almost exclusively to the molecular-morphological couplet. However, in many metazoan
taxa, the presence of skeletal parts or poorly preserved soft parts is dominant in collections, making it difficult to extract
genetic material. This is the case with many invertebrates and unfortunately a very common situation in mollusk collections.
Herein we carry out a phylogenetic analysis of the transisthmian American tellinid bivalve genus Eurytellina based
on anatomical and morphometric characters, using different ways to analyze the morphometric data under parsimony-based
methods. Species in this genus are recognized as deep infaunal burrowers and present a strong filter-feeding apparatus. We
included 144 taxonomically important morphoanatomical and morphometric characters and 19 landmark characters. The
main results are a) Tellinota (formerly a synonym of Eurytellina) is confirmed as a taxon restricted to Africa; b) Eurytellina
lineata is confirmed as sister group to all the other members of the genus; c) there is strong evidence for three robust clades,
here named as groups trinitatis, nitens and punicea; d) some transisthmian sister species hypotheses are confirmed—although
the pattern of speciation and radiation may be related to a complex long-term elevation of the Panama Isthmus and previous
events (probably since the early Cenozoic). Furthermore, several new anatomical characters are described within the Order
Tellinoidea, which should be considered in future studies.
... Regional Studies in Marine Science 81 (2025) 103978 and gill nets. Subsequently, all the specimens were identified to the lowest possible taxonomic level based on taxonomic descriptions and identification guides for bivalves (Poutiers, 1998a;Huber, 2010Huber, , 2015Hamli et al., 2015Hamli et al., , 2016, gastropods (Poutiers, 1998b;Reid, 2014;Reid and Ozawa, 2016;Baharuddin et al., 2017;Mustapha et al., 2021;Robin, 2021), malacostracans (Chan, 1998;Ng, 1998;Ngoc-Ho, De Saint Laurent, 2009;Sakai and Türkay, 2012;Lin et al., 2016) and merostomatids (Baylon and Alcantara-Creencia, 2022). Finally, all species names were validated using the World Register of Marine Species (WoRMS) (http s://www.marinespecies.org) ...
... The taxonomic status of Geloina erosa has been a contentious issue for the past decade. The debate originated when Huber (2015) recognized G. erosa as a junior synonym to G. expansa based on conchological traits. This was exacerbated when two prominent websites, the World Register of Marine Species (WoRMS) (https://www.marinespecies.org) ...
... In this study, we focus on the genus Lithophaga. There are nine living species currently recognized (Huber, 2010(Huber, , 2015 MolluscaBase 2022) but two of these [Lithophaga punctata Hoeksema 2002 andLithophaga cylindrica (Krauss, 1848)] are of uncertain status. They are characterized by a dark brown periostracum with some fine, antimarginal ribbing and absence of extra-periostracal encrustations. ...
... However, this stance is unlikely and is not supported by as yet limited molecular data (Liu et al., 2018). Additionally, there remain some unresolved nomenclatural problems concerning the two common western Atlantic species of Lithophaga -Lithophaga nigra and Lithophaga antillarum (see Bieler, 2010;Huber, 2015) but we follow their current status as recorded in MolluscaBase (2022). ...
Phosphate mineralization as a skeletal material is uncommon in invertebrate animals and rare in Mollusca. Remarkably, apatite minerals were first reported more than 30 years ago in the periostracum of two species of the mytilid bivalve Lithophaga where shells are mostly constructed of calcium carbonate. This discovery extended the range of biominerals secreted by molluscs but has attracted no subsequent research. In this study we review the occurrence of phosphate mineralization in Lithophaga and putatively allied taxa. Lithophagine bivalves, particularly Lithophaga and the more diverse Leiosolenus species, are well known for their endolithic chemical dissolution of calcareous rocks and corals with calcium-binding lipoproteins secreted by mantle glands. Fluorapatite was identified by X-ray diffraction in an outer layer of the periostracum in six species of Lithophaga. Morphological study by scanning electron microscopy of four species showed the fluorapatite crystals embedded in periostracal material in a layer 10–20 µm thick. Dilute bleach treatment revealed the crystals as densely packed euhedral prisms 250–400 nm in size. The succeeding inner layers of the periostracum were unmineralized. Observations of the developing periostracum of Lithophaga teres suggest that the initial mineralization is in the form of amorphous granules that coalesce and transform into euhedral crystals. Periostracal phosphate was not recorded in other members of the Lithophaginae – Leiosolenus, Botula or Zelithophaga species. Leiosolenus species characteristically have extraperiostracal aragonitic encrustations that can be thick and structurally complex. Published molecular phylogenies of Mytilidae bivalves show a division into two major clades with Lithophaga species in one clade and Leiosolenus species in the other, indicating that the subfamily Lithophaginae as presently understood is polyphyletic. This result implies that the two genera have independent evolutionary pathways to endolithic occupation of calcareous substrates although using similar mantle gland secretions to excavate their crypts. Because fluorapatite is considerably less soluble and harder than calcium carbonate, it is suggested that the phosphate layer of Lithophaga is a functional adaptation to protect their shells from self-dissolution from their rock-dissolving glandular secretions and may also act as defence against other shell-eroding organisms.
... The Unionidae is the richest of the six extant freshwater mussel families, there are currently 674 species known globally, with (80%) of them being widely dispersed over temperate North America and Eurasia in addition to tropical Mesoamerica, Africa, and southeast Asia (Huber, 2010(Huber, , 2015. According to the International Union for Conservation of Nature's (IUCN) assessment of the majority of freshwater mussel species (517), 6% extinct, 7% vulnerable, 9% ...

Freshwater mussel descriptions from the early 19 th century up till the mid-20th century included hundreds of Unio species described from many regions of the world (Huber, 2015). ...
Freshwater mussels are a guild of stationary, suspended-feeding species; they perform significant ecological functions like nitrogen cycling, bioturbation that gives oxygen and habitat that other creatures need to survive, and increasing water clearance by filtration. Knowledge of the freshwater mussel Unio tigridis Bourguignat, 1852, distribution, and molecular study in Iraq was inadequate. In the current study, this species of freshwater Mussels belonging to the family Unionidae was collected from different locations in the Greater Zab River, from April to August 2022. The average water temperature of the site was arranged between (17.8 to 36.1 C°). All previous studies in the Kurdistan Region and Iraq were based on morphological characters and the current study was the first report of Unio tigridis that was confirmed by molecular genetics and COI gene, analyzed phylogenetically using Maximum Likelihood and Maximum Parsimony Methods.
... Clams of the nonmarine genus Corbicula Megerle von Mühlfeld, 1811(Cyrenidae Gray, 1840 are characterized by shells with serrated lateral teeth and the lack of a pallial sinus (Huber, 2015). Having a native range in South and East Asia, Africa and parts of Australasia, these bivalves are effective invaders of freshwater and brackish-water ecosystems in Europe and the Americas (Starobogatov, 1970;Korniushin, 2004;Bieler & Mikkelsen, 2019). ...
... He & Zhuang (2013) recognized 19 species of Corbicula in China. According to the estimate by Huber (2015), worldwide there might be 60-70 Corbicula 'species', delineated chiefly on the basis of shell morphology. Graf & Cummings (2020) have listed as many as 91 valid species for this genus. ...
Here, we investigate the shell shape variation of some closely related freshwater species of the bivalve genus Corbicula using descriptive (qualitative), geometric morphometric and traditional conchometric approaches. The combination of these different approaches allows for an effective discrimination between the species C. fluminalis, C. fluminea and C. leana, as well as an unidentified Corbicula sp. The roundness of the shell hinge is an important diagnostic feature, as are shell sculpture (ribs), symmetry of the apertural margin, and both position and extension of the umbo. We also identify possible hybrids between C. fluminalis and C. leana, with these showing features intermediate to those of the parent species. We examine variability of shell features of C. leana in selected areas in Europe and compare these results with material from the native range of Japan and Korea. For C. leana, we identify two geographic morphotypes from the native area; within Europe, there is a high morphological diversity of this species with several new forms arising, most probably as a result of hybridization.

The exceptional Pliocene marine faunal assemblages of west-central Portugal have been known since the late 19th century. They include highly diverse molluscan faunas whose study is far to be completed. Discovered nearly 40 years ago, Vale do Freixo (Carnide, Pombal) is perhaps the most outstanding fossil site. Nevertheless, the bivalves remain relatively unknown. This study focuses on the taxonomy of this relevant group of marine Mollusca. The research, based on a detailed sampling of three fossiliferous beds from the Carnide Formation, yielded a list of 85 species belonging to 75 genera and 32 families. Forty-three species are new for the Carnide area and twenty-three are reported for the first time in the Portuguese Pliocene, increasing to 115 the number of known species in the Mondego Basin in the Beira Litoral.
... Turner (1966) synonymized many teredinid species with similar or identical pallet morphology. This reduced the number of species by over half and expanded the geographic range of many recognized species, an action which Huber (2015) considered too extreme in some cases. The merging of some congeners requires reconsideration given that investigations into Teredinidae life histories, biogeography, and phylogenetic relationships have revealed cryptic species among taxa submerged into synonymy. ...
... Turner (1966) stated that P. pentagonalis was "probably" a synonym of Nototeredo edax based on Habe's description and drawings, and lists it as such in Turner (1971). The synonymy of P. pentagonalis with N. edax was accepted by Inaba and Oyama (1977), Kuroda and Habe (1981), but questioned by Tsunoda (1979) and Huber (2015). Okutani et al. (2009) rejected this synonymy, noting clear differences in pallet morphology, suggesting that their Psiloteredo specimens were P. megotara, and that an examination of the type material of P. pentagonalis would be required for confirmation. ...
Cryptic species are a common phenomenon in cosmopolitan marine species. The use of molecular tools has often uncovered cryptic species occupying a fraction of the geographic range of the original morphospecies. Ship-worms (Teredinidae) are marine bivalves, living in drift and fixed wood, many of which have a conserved morphology across cosmopolitan distributions. Herein novel and GenBank mitochondrial (cytochrome c oxidase subunit I) and nuclear (18S rRNA) DNA sequences are employed to produce a phylogeny of the Teredinidae and delimit a cryptic species pair in the Psiloteredo megotara complex. The anatomy, biogeography, and ecology of P. megotara, Psiloteredo sp. and Nototeredo edax are compared based on private and historic museum collections and a thorough literature review. Morphological and anatomical characters of P. megotara from the North Atlantic and Psiloteredo sp. from Japan were morphologically indistinguishable, and differ in pallet architecture and soft tissue anatomy from N. edax. The two Psiloteredo species were then delimited as genetically distinct species using four molecular-based methods. Consequently, the Northwest Pacific species, Psiloteredo pentago-nalis, first synonymized with N. edax and then with P. megotara, is resurrected. Nototeredo edax, P. megotara and P. pentagonalis are redescribed based upon morphological and molecular characters. Phylogenetic analysis further revealed cryptic species complexes within the cosmopolitan species Bankia carinata and possibly additional cryptic lineages within the cosmopolitan Lyrodus pedicellatus.
... Leveraging modern and updated data for various biotic groups, often at the family or order level (primarily for the Triassic and younger periods), facilitated the accurate estimation of habitat ranges for specific taxa across different taxonomic levels (Bevilacqua et al., 2021). Several families of ostracods and bivalves went from Devonian through the Permian-Triassic event, although their diversity at the event reduced drastically (Crasquin & Forel, 2014;Forel & Crasquin, 2022;Huber, 2015), and their paleotemperature evaluation at the family level during Late Paleozoic and Triassic is consistent. The ecological and paleoenvironmental data from the regional studies in Siberia and surrounding areas (Abramov, 1970;Abramov & Grigorieva, 1983;Abushik, 1990;Biakov, 2010Biakov, , 2012Biakov, , 2020Bushmina & Kononova, 1981;Bychkov et al., 1976;Kurushin, 1992;Kutygin et al., 2020Kutygin et al., , 2024Nikolaeva & Neustrueva, 1999;Polenova, 1960;Sarycheva, 1977;Sarycheva et al., 1963;Sobolev, 1989), were also analyzed in respect of the bathymetry and paleotemperature evaluation. ...
This study introduces a novel approach for quantitatively assessing sea‐surface paleotemperatures examined in the Upper Paleozoic of Siberia, utilizing the obtained in the region data as a case study of the use of this method. The method relies on evaluating the taxonomic composition and ecological proxies of biota. It utilizes a comprehensive dataset encompassing the geographic distribution and ecology of various biotic groups in Siberia and adjacent regions, leveraging the newly developed by the authors large PaleoSib database and partially the Paleobiology Database (paleobiology.org) The taxonomy has been used according to the database of Global Biodiversity Information Facility (gbif.org). Fossils collected from individual locations often exhibit a wide spectrum of paleotemperatures. To address this variability, we developed an algorithm for calculating average biotic paleotemperatures in each locality/time slice. Our computations of the available data have unveiled a coherent pattern of paleoclimate dynamics, particularly Sea Surface Temperature, across Siberian basins and surrounding areas during the Late Paleozoic era. These findings significantly contribute to a refined comprehension of paleoclimate and paleotectonic dynamics in the region during that specific time. To enhance paleotemperature analyses, we have integrated lithological indices with biotic ones, fortifying the overall methodology and furnishing a more robust framework for interpreting paleoclimate data. The method could be a helpful tool in regional and interregional studies, regardless of the utilized rock's age and fossil groups.
... The body size of each individual was calculated using shell area, as approximated by an ellipse (Calderaro et al., 2024); shell length (the anterior-posterior dimension of the shell parallel to the hinge) and height (the dorsal-ventral dimension perpendicular to the length measurement) were measured using a Leica M125 stereomicroscope. Other functional categories were determined based on a literature review (Mikkelsen and Bieler 2008;Huber 2010Huber , 2015Rocha and Matthews-Cascon 2015;Audino and Marian 2018;Taylor and Glover 2021). The degree of phylogenetic conservatism of these functional traits varies across the Bivalvia, and most of these assignments were made at the genus or family level; a dearth of inter-and intraspecific studies makes it challenging to assess variation in bivalve functional traits at finer taxonomic scales. ...

A new species of deep-sea thyasirid (Bivalvia: Thyasiridae), Ascetoaxinus ravichandrani sp. nov., is described and illustrated from material collected in the northern Indian Ocean during the FORV Sagar Sampada deep-sea cruise no. 404. Specimens were collected from a depth between 1007 m and 1038 m off Kanyakumari, Gulf of Mannar, Tamil Nadu, South India. This is the first record of the genus Ascetoaxinus from the Indo-West Pacific. The new species is compared to A. quatsinoensis P.G. Oliver & Frey, 2014 from the Northeast Pacific and A. ovoideus (Dall, 1890) from the Northwest Atlantic. It can be distinguished from these species by its external shell characters. Further comparisons are made between the new species and other larger thyasirids recorded from deep waters around India, notably Channelaxinus investigatoris E.A. Smith, 1895. The distinctions and similarities among these species are discussed, highlighting the key features that set A. ravichandrani apart from related species.
... Cyrenoida Joannis, 1835, is a poorly known genus comprising six living species with infaunal filter-feeding habits that inhabit nutrient-rich sediments in the brackish waters of estuaries and mangroves across Western Africa, the Western Atlantic, the Eastern Pacific of North and Central America, and the Caribbean islands (Coan and Valentich-Scott 2012;Huber 2015;Valentas-Romera et al. 2019;Wu et al. 2023). Historically, this genus has been associated with lucinids, but recent phylogenetic studies have placed it within the Cyrenoididae, primarily consisting of species found in brackish, estuarine, or freshwater environments (Taylor et al. 2009;Lemer et al. 2019;Wu et al. 2023). ...
Cyrenoida implexa sp. nov. is the first species of Cyrenoididae in the Southern West Atlantic. This new species exhibits external similarities to C. floridana but is distinguished by distinct right hinge dentition, larger siphons and a more extensive siphonal area at the mantle border, an incurrent siphon with three rows of papillae, a lack of papillae at the middle mantle fold, and smaller adductor muscle volume. In the environment, it possesses a higher saline tolerance than C. floridana.

... An additional two seasons of samples, i.e., spring 2022 and autumn 2023 were processed by the author. Invertebrate taxa were identified using available literature for crustaceans (Poore 2004, Poore & Ahyong 2023, molluscs (Huber 2010, Huber 2015, Reid et al. 2016, Robin 2021, and echinoderms (Dartnall 1980, Marsh & Fromont 2020, and by referring to the contemporary taxa list and photographic reference collection generated by the Westport WAMSI marine science program. To ensure consistency among identifications, specimens of each taxa were retained, added to an identification reference collection held at the WAM, and supplied to the respective expert taxonomist at the museum to confirm identification. ...
Coastal waters are biodiverse and highly productive ecosystems, supporting various habitats and providing refuge, nutrition, and favourable physical conditions for many species. These ecosystems are also valuable for commercial, industrial, and recreational purposes, and consequently, many have been negatively impacted by anthropogenic activities. Despite their importance, relatively little information is known about how these activities impact the biota coastal waters support, particularly the invertebrate communities. This study examined the long- and short-term temporal and spatial variation in the megabenthic invertebrate fauna of Cockburn Sound, a heavily utilised coastal embayment in temperate Western Australia, within which there is a proposal to construct a new container port. Firstly, a suite of interdecadal analyses were conducted by comparing trawl data from seven sites across Cockburn Sound sampled in two seasons in 2007/08 and 14 years later in 2021/22 to determine whether there had been a shift in the characteristics of the megabenthic invertebrate community. Secondly, a contemporary analysis focussing on seasonal, short-term interannual, and spatial variation was conducted using the data from 2021/22 and additional samples collected in 2022/23. From the interdecadal analyses, a total of 214 invertebrate taxa representing 17 classes and six phyla were recorded for the two surveys. There was a substantial decline in abundance, biomass, and diversity measures between decades, with a clear shift in community composition. The largest temporal declines in abundance were for arthropods and echinoderms, two pollution and disturbance-sensitive phyla. Abundance-biomass curves revealed a contrasting viewpoint of undisturbed ecosystem condition due to the dominance of large-bodied opportunistic crustaceans in both decades. A total of 175 taxa from 15 classes and six phyla were recorded in the contemporary sampling, with the community significantly differing in diversity measures, abundance, and biomass across sites and between seasons, highlighting finer-scale spatial and seasonal influences that act on the community. Fluctuating abundances of crustacean, mollusc, and echinoderm taxa were apparent, with greater abundances in autumn of 2022/23. A gradient of declining diversity measures moving southwards in the Sound was apparent, most clearly expressed by taxa richness. The findings of this study document concerning patterns in the invertebrate communities of Cockburn Sound across decades and likely display the cumulative detrimental effects of press (e.g. sediment eutrophication, increased industrialisation) and pulse (e.g. marine heatwave, hypoxia event) disturbances. This study showcases the value of historical data sets in forming a comprehensive view of contemporary invertebrate community trends and the data will be useful in the environmental impact assessment of the proposed container port development.
... The family Galeommatidae sensu Ponder (1998) is a group of tiny marine bivalves, with approximately 620 described species and numerous undescribed species (Huber, 2015). Many commensal species within this family live attached to the body surface or burrow walls of benthic invertebrates (Boss, 1965;Morton and Scott, 1989;. ...
Sagamiscintilla thalassemicola (Bivalvia: Galeommatoidea: Galeommatidae) is a rare ectocommensal bivalve that lives on the proboscis of echiuran worms, Anelassorhynchus spp. (Annelida: Thalassematidae: Thalassematinae: Thalassematini), and has been known only from the temperate zones of Japan. In this study, we found S. thalassemicola on the proboscis of the large echiuran Ochetostoma sp. (Thalassematidae: Thalassematinae: Thalassematini) on intertidal flats of three islands of the Ryukyu Archipelago, southern Japan. These are the first records of S. thalassemicola on non- Anelassorhynchus hosts and also from the subtropical regions. Additionally, we also collected S. thalassemicola from an intertidal flat of Kushimoto, Wakayama, Kii Peninsula, Japan, which is an update of the easternmost record of this species. The genetic differences in the mitochondrial cytochrome c oxidase subunit I and nuclear internal transcribed spacer 2 genes among S. thalassemicola , including those with Ochetostoma sp. from the subtropical region and with Anelassorhynchus spp. from the temperate region, can be considered within the intraspecific variation. These suggest that S. thalassemicola uses different echiuran hosts in the temperate and subtropical regions, respectively.
... The genus Corbicula in Japan includes C. fluminea, the freshwater monoecious C. leana (Prime 1867), the dioecious C. sandai (Reinhardt 1878) from the Lake Biwa and Yodo River systems, and the brackish dioecious C. japonica (Prime 1864). Of these, C. leana has been considered a native Japanese species, but because it is not taxonomically organized and genetic differences from C. fluminea cannot be confirmed (Yamada et al. 2010), it has recently become regarded as synonymous with C. fluminea (Huber 2015). The present study follows this trend. ...
An environmental DNA (eDNA) detection technique using TaqMan qPCR and LAMP analysis was developed for the Asian clam Corbicula fluminea, which is causing alarm in Japan and worldwide as an invasive alien species. The qPCR primer and probe designed in this study specifically amplified C. fluminea DNA, but did not amplify C. sandai or C. japonica DNA, both native Japanese species. In contrast, LAMP analysis showed that C. sandai DNA also reacted, but with a delay after the amplification of C. fluminea DNA, and it was possible to specifically detect C. fluminea DNA by setting the LAMP analysis time to 30 min. Field surveys at three study sites with different habitat conditions for C. fluminea showed that eDNA detection using qPCR/LAMP analyses were consistent with C. fluminea distribution. The applicability of a simple filtration and concentration method for eDNA using glass fibers in suspension (SGF method) was verified, and the SGF method had a higher eDNA recovery capacity than the conventional aspiration method using glass fiber filter paper. eDNA extraction using the SGF method and eDNA analysis using qPCR/LAMP may be useful for qualitative and simple habitat estimation of C. fluminea in poor water quality environments.
... The burrows of Maxmuelleria lankesteri (Herdman, 1897), which is a large bonelliin species living in sandy sediment bottoms in Scotland, are inhabited by facultative commensals, such as the hesionid polychaete Oxydromus flexuosus Delle Chiaje, 1827, two galeommatid bivalve species, Kurtiella bidentata Montagu, 1803 andSaxicavella jeffreysi Winckworth, 1930, and a gobiid fish Gobius niger Linnaeus, 1758 (Nickell et al. 1995). Saxicavella is a genus closely related to Basterotia and belongs to the same subfamily Basterotiinae (Huber 2015). It is interesting that Oxydromus polychaetes and basterotiin bivalves were recorded from both the burrows of M. lankesteri and Bo. ...
Dead coral rocks are prevalent hard substrates in shallow warm waters, providing habitat for various infaunal and boring invertebrates. Despite this, the nature of species interactions, especially symbiotic relationships, among them remains poorly understood. Bonellia (Annelida: Thalassematidae: Bonelliinae) is a group of greenish echiuran worms commonly inhabiting cavities inside dead coral rocks. Although echiuran burrows in marine sediments are known to harbour various host-specific macrosymbionts, it remains unclear whether such associations also occur in hard substrates. To address this, we investigated the diversity of macrosymbionts associated with the burrows of Bonellia sp. aff. minor in the warm-temperate coast of the Kii Peninsula, Japan, and the evolutionary origins of those symbionts. The host’s burrow morphology was also examined using micro-computed tomography (CT) scanning. Our field survey revealed that the burrows of Bo. sp. aff. minor hosted three commensal species including a polychaete, Oxydromus fauveli, and two new species, a bivalve (Basterotia bonelliphila sp. nov.) and an amphipod (Leucothoe bonelliae sp. nov.). Our molecular phylogenetic analyses showed that each symbiont species belongs to a clade comprising commensal species specific to echiurans or annelids. Overall, our findings contribute to a better understanding of symbiotic associations in marine hard substrates.

Моллюски рода Corbicula, впервые обнаруженные в нижнем течении р. Дон (район тёплого канала Новочеркасской ГРЭС) в 2017 году, по конхиологическим признакам ранее были идентифицированы как Corbicula fluminea. Целью настоящей работы стало получение новых данных по морфометрии и особенностям формообразования раковин моллюсков данного вида в онтогенезе. По результатам анализа основных морфометрических параметров раковины – длины (L), ширины (D) и высоты (H) – показаны изменения индексов её фронтальной (D/L) и сагиттальной (H/L) кривизны (=индекс округлости), выпуклости ((H+D)/L) и условного объёма (H×D×L/1000) в онтогенезе. Приведены соответствующие уравнения зависимостей. Сделан вывод об интервальном характере изменений указанных индексов кривизны, определяющих соответствующие изменения относительного объёма раковин в онтогенезе. Их графики имеют куполообразный характер с достижением значений в диапазоне длин раковин 15–25 мм, что достоверно превышает аналогичные значения в интервалах до 15 и более 25 мм. Половое созревание и начало размножения моллюсков происходит на этапе увеличения относительного объёма раковины. Подобная стратегия формообразования, направленная на создание максимального внутреннего относительного объёма раковины в период формирования гонады, тем более у вынашивающей личинок андрогенной C. fluminea, может являться одной из характеристик, определяющих репродуктивные возможности вида, и, следовательно, его инвазивный потенциал.

Study of the diversity and spatial distribution of molluscs along salinity gradient in Ashtamudi Lake recorded the presence of 83 species with one polyplacophoran, 41 gastropods, 37 bivalves and four cephalopods. The species diversity in various salinity zones was in the order: saline zone-80 species > estuarine zone-28 species > freshwater zone-14 species. The report includes three species new to the west coast of India: Assiminea woodmasoniana G. Nevill, 1880, Rugalucina vietnamica (Zorina, 1978) and Platevindex martensi (Plate, 1893). Species: such as Chiton granoradiatus Leloup, 1937; Clithon sowerbianum (Récluz, 1843); Littoraria pallescens (Philippi, 1846); Acteocina decorata (Pilsbry, 1904); Alaona ala (Hanley, 1845) and Serratina siamensis (E. von Martens, 1860) are new to Kerala. The paper analyses the alpha and beta diversity of molluscs in the Ashtamudi Lake, Kerala.
... IPBES 2019 7 ) to rapidly expand our identification of nature's contributions to people and the direct threats of anthropogenic pressures to the persistence of species and their ecosystem services. Extensions of our analyses should include, for example, changes to intrinsic vulnerability when geographic ranges of species expand due to human introductions into new areas, and should also investigate why natural populations often fail to recover when exploitation is reduced or stopped: for example, are they entirely driven by crossing demographic thresholds driven by human-stressors, such as habitat conversion and pollution 84,86,[99][100][101][102] , and/or other ecological interactions such as changes in food web structure 3,75,76 ? ...
Marine bivalves are important components of ecosystems and exploited by humans for food across the world, but the intrinsic vulnerability of exploited bivalve species to global changes is poorly known. Here, we expand the list of shallow-marine bivalves known to be exploited worldwide, with 720 exploited bivalve species added beyond the 81 in the United Nations FAO Production Database, and investigate their diversity, distribution and extinction vulnerability using a metric based on ecological traits and evolutionary history. The added species shift the richness hotspot of exploited species from the northeast Atlantic to the west Pacific, with 55% of bivalve families being exploited, concentrated mostly in two major clades but all major body plans. We find that exploited species tend to be larger in size, occur in shallower waters, and have larger geographic and thermal ranges—the last two traits are known to confer extinction-resistance in marine bivalves. However, exploited bivalve species in certain regions such as the tropical east Atlantic and the temperate northeast and southeast Pacific, are among those with high intrinsic vulnerability and are a large fraction of regional faunal diversity. Our results pinpoint regional faunas and specific taxa of likely concern for management and conservation.
... Finally, although living Mactridae are well represented in Japanese waters (Habe, 1977(Habe, , 1981, Rugosoxyperas, based on a fossil type species, was registered from Pleistocene deposits of Japan (Nomura and Zinbo, 1934). Altogether, >100 genus-level names have been proposed within the family Mactridae, 79 of which are considered valid in the literature (Huber, 2010(Huber, , 2015Cosel and Gofas, 2019;Signorelli, 2019;Valentich-Scott et al., 2020;MolluscaBase, 2022;among others). However, only 45 genera are based on fossil specimens as type species. ...
All genera based on fossil type species belonging to the family Mactridae are alphabetically listed in this work. The oldest records of the Mactridae come from Cretaceous deposits of North America. However, this group of bivalves has been worldwide recorded from the Paleogene and Neogene. An emended diagnosis for each genus is herein provided. In addition to that, type species, type localities, and occurrences are included. For each genus, a remarks section includes the most recent published taxonomic opinions. Nevertheless, in some cases, new taxonomic decisions based on morphological analysis of types have been taken. Genera based on extant type species are excluded from this work. Forty-five genera are listed herein and type material has been reproduced wherever possible. Ionesimactra nom. nov. is proposed as a replacement name for Caspimactra Ionesi (non Caspimactra Ali-Zade and Kabakova). This work constitutes the basis for future revisions related to fossil taxa of the family Mactridae from different regions.

... The family Donacidae (Bivalvia) includes more than 100 species and 14 living subgenera (e.g., Dall 1892;Lynge 1909;Lamy 1914;Wade 1967;Coan 1973Coan 1983Subba Rao and Dey 1986;Paredes and Cardoso 2001;Huber 2010Huber 2015. The members of this family are distributed in warm waters around the world (Abbott 1974;Ansell 1985;Huber 2010) and vary in shell shape and colour (Ansell 1985;Donn 1990;Soares et al. 1998;Huber 2010;Tan and Low 2013;Ambarwati and Faizah 2017;Signorelli and Printrakoon 2020). ...
The phylogenetic relationship of living Thai Donacidae was herein studied. Two methodologies, geometric morphometrics (GM) and genetic analysis of COI sequences, were combined and applied to identify the valid taxa and explain biodiversity and the distribution pattern in this family. A total of 587 living specimens were tested to analyze the shape and size patterns by Elliptic Fourier Analysis (EFA). Shell identification and GenBank sequences were added to construct the phylogenetic relationship and haplotype network. Centroid size was used to identify the specimens to the subgenus level. Donax (Hecuba) scortum, was easily distinguished from other species by Principal Component analysis (PCA) of shell size and shape. Donax (Dentilatona) incarnatus and Donax (Deltachion) semisulcatus semisulcatus were identified using Canonical Variates Analysis (CVA). Pairwise comparison of EFA was used for species level recognition, particularly shape overlap was observed for medium and small shell size. Based on genetic distance and haplotype network of COI sequences, Donax (Latona) faba and D. (Latona) solidus could be grouped in the same clade. Intraspecific and interspecific genetic data variation of some common species in different geographical localities of Thailand was observed. Three distribution patterns of Donax species were observed along the two-marine system of Thailand.

One hundred sixty species of Bivalvia from the Campanian of Hannover are discovered. Shells from the following families are found: Nuculidae, Malletiidae, Mytilidae, Noetiidae, Arcidae, Glycymerididae, Inoceramidae, Arctostreidae, Ostreidae, Gryphaeidae, Bakevilliidae, Pinnidae, Dimyidae, Anomiidae, Pectinidae, Neitheidae, Spondylidae, Entoliidae, Oxytomidae, Limidae, Astartidae, Radiolitidae, Plagioptychidae, Lucinidae, Thyasiridae, Cardiidae, Arcticidae, Teredinidae, Cuspidariidae, Pholadomyidae,
... The body size of each individual was calculated using shell area, as approximated by an ellipse (Calderaro et al., 2024); shell length (the anterior-posterior dimension of the shell parallel to the hinge) and height (the dorsal-ventral dimension perpendicular to the length measurement) were measured using a Leica M125 stereomicroscope. Other functional categories were determined based on a literature review (Mikkelsen and Bieler 2008;Huber 2010Huber , 2015Rocha and Matthews-Cascon 2015;Audino and Marian 2018;Taylor and Glover 2021). The degree of phylogenetic conservatism of these functional traits varies across the Bivalvia, and most of these assignments were made at the genus or family level; a dearth of inter-and intraspecific studies makes it challenging to assess variation in bivalve functional traits at finer taxonomic scales. ...
Ocean deoxygenation is a growing concern globally. Oxygen is less soluble in warm water, and warming temperatures also result in the slowdown of ocean circulation which limits oxygen delivery to deeper waters. Anthropogenic eutrophication has also contributed to the development of hypoxic conditions in many coastal areas. Here we investigate biodiversity structure along an environmental gradient in the Gulf of Mexico to see how patterns of spatiotemporal turnover can inform future biotic response of benthos to ocean deoxygenation. Live and dead assemblages of bivalve mollusks were collected at 15 stations offshore Louisiana, Alabama, and Florida. Abundance and body size data were collected, and specimens were classified functionally using information about feeding, attachment, life position, and body size. Environmental conditions were characterized using multi-decadal mean sea surface temperature (SST), dissolved oxygen (DO), and net primary productivity (NPP), and grain size data from our field samples. Stations in the north-central Gulf affected by Mississippi River discharge are characterized by higher NPP, lower DO, and higher percentages of silt and clay than stations in the northeastern Gulf. Both taxonomic and functional diversity significantly covary with this environmental gradient, with the lowest diversities observed at stations in the core of Louisiana’s “dead zone.” Analyses of spatiotemporal turnover patterns reveal shifts in the dominant feeding mode, with hypoxic environments containing a greater abundance of deposit and mixed feeders, compared with more oxygenated environments that host an abundance of suspension feeders and are characterized by a greater variety of feeding ecologies. Live-dead analyses reveal a shift in taxonomic and functional diversity in coastal Louisiana, that appears to coincide with the onset of anthropogenic eutrophication in these coastal settings.
... However, this structure changes when extracting animals from wood and can become damaged or deformed due to ecological conditions (shown by white arrows) (Velásquez and López 2016). Thus, other anatomical characteristics, such as the anatomy of the digestive system, siphon structure, pigmentation, shell valves, etc., should be considered for classifying their characteristics in addition to the palette (MacIntosh 2012;Huber 2015;Shipway et al. 2016;Borges and Merckelbach 2018). Based on the results of morphology identification on the pallet from this study, the Tambelo sample was similar to B. thoracites in Malaysian waters (Lee et al. 2019) ( Figure 5B). ...
Akabessy JL, Yahya, Fadjar M, Suprayitno E. 2022. Identification of Tambelo (Bactronophorus thoracites) in Wamesa Waters, Manokwari, West Papua, Indonesia. Biodiversitas 23: 6021-6030. Tambelo, otherwise known as shipworm, is a marine bivalve mollusk comprising 16 genera in the Teridinidae family, of which Teredo is the most frequently mentioned. Furthermore, the only species in the genus Bactronophorus is the wood borer, Bactronophorus thoracites (Teredinidae), which has a wide distribution in the Indo-West Pacific biogeographical region. Identifying shipworm species is difficult due to their high diversity and the limited information about their taxonomic characteristics, which often leads to identification errors by collectors. Papuan people consume tambelo as a substitute for side dishes because they are believed to be able to cure various diseases. Therefore, this study aims to establish by morphology and molecular analysis that tambelo belongs to the B. thoracites of the Teredinidae family. Tambelo was identified using the morphological method of observing the physical characterization of the palette, which is unique between genera. It was collected from a mangrove forest near Wamesa Beach, South Manokwari, Manokwari Regency, Indonesia. Meanwhile, this study adopted PCR, an identification method that uses DNA from a small number of samples and can provide a DNA sample sequence. Morphological analysis based on pallet characterization showed that the characteristics of the tambelo pallet were similar to those of the B. thoracites based on the identification book. In addition, the molecular phylogenetic analysis using two mitochondrial protein-coding genes, cytochrome c oxidase subunit I (COI), showed tambelo was 91% similar to B. thoracites from mangroves environment on the west coast of Peninsular Malaysia, Malaysia.
... Species determinations were primarily based on comparisons with identified material in the ZRC, and by checking against the original descriptions, revisionary treatments and popular references (e.g., Reid, 2007;Huber, 2010Huber, , 2015 and other references cited herein). Herein, species names prefixed with 'aff.' indicate affinity to the stated species, but is decidedly not conspecific, while 'cf.' indicates comparison, and possible conspecificity, with the named taxon. ...
Pulau Satumu is the southernmost islet within Singapore’s territorial jurisdiction. It is often referred to as Raffles Lighthouse or Raffles Light after its lighthouse, which began operating in 1855. Some notes of interest on the islet’s etymology and history, such as the earliest known name being “the Coney” or “Coney Island”, are provided. We present a first inventory of the mollusc species of Pulau Satumu, which is of some significance as the islet is one of the marine areas recently proposed to be of conservation priority in the Singapore Blue Plan 2018. A total of 328 species, compiled from records in the literature, and original data from a recent biodiversity survey in 2020 and existing material deposited in the Lee Kong Chian Natural History Museum, are listed. The class Gastropoda is most speciose with 232 species in 69 families, followed by the class Bivalvia with 92 species in 26 families, then the classes Polyplacophora and Cephalopoda, each with two families and two species. Records of five species, Nerita signata, Drupa albolabris, Drupa morum, Drupa ricinus and Morula uva, are regarded as likely to be erroneous. More than 250 species are figured; the vast majority of them are of available voucher material.
... Starting from M. Huber (2010Huber ( , 2012Huber ( , 2015 and Signorelli & Printrakoon (2019) and based on insights gained from the review of hundreds of lots of Donacidae from the region and more than a 1500 from the Indo-West Pacific, all records have been checked and only verifiable records have been used. Species lists without descriptions and illustrations are excluded as identifications cannot be checked, e.g., the record of Donax brazieri Smith, 1892 from ne Thailand (in Sanpanich, 2011), marked as first record from that country. ...
Based on lots in collections, literature data and type material, the living Donacidae of the South China Sea and East Asia are reviewed. At least 35 nominal species have been recorded for this area, including numerous synonyms and misidentifications. Thirteen valid species (one including two subspecies) are recorded from the area. For all species the variation in their shells and their distribution are described. It is evident that despite recent reviews the identification of Donacidae remains challenging and several taxonomic issues are addressed in this paper. Two new species are described: Donax (Deltachion) spiniferus spec. nov. and Tentidonax borneensis spec. nov. The true identity of Donax semisulcatus Hanley, 1843 is revealed and Donax (Latona) bicolor Gmelin, 1791 is recognised as valid species. Substantial new information is provided for Donax (Deltachion) bruneirufi M. Huber, 2012 and Donax (Latona) listeri Hanley, 1882 (previously only recorded from a single locality each). Because of their consistent considerably smaller size, sculpture and different habitat Tentidonax Iredale, 1930 is raised to genus level.
... However, the genus Adipicola is considered paraphyletic (Lorion et al. 2013;Thubaut et al. 2013aThubaut et al. , 2013b. Thus, the taxonomy of this group of bivalves is not definitive and contrasting classification approaches have been presented in different works (Dell 1987(Dell , 1995Huber 2010Huber , 2015. According to recent literature, the number of species included within Adipicola is not definitive. ...
New material collected at a methane seep site off central Chile (36°21.997′S, 73°42.785′W), known as the Concepción Methane Seep Area (CMSA), revealed the presence of the genus Adipicola in the SE Pacific. Dead individuals consisting of empty single and articulated valves were collected from vesicomyid clam beds, at 690 m depth by the remotely operated vehicle KIEL 6000, using scoop nets. Shell characters, such as equivalve, antero-posteriorly elongate shell, external surface smooth without periostracal hair, not gaped and hinge plate without teeth or crenulations, were observed and compared with the morphology of described species within the genus. Based on these morphological characters we tentatively assign the individuals belonging to Adipicola leticiae previously never found below 27°S in the SE Pacific. This new finding constitutes the first record of an extant Bathymodiolinae mussel off central Chile. The current knowledge of additional chemosymbiotic bivalves at the CMSA is discussed. The present study updates and contributes to the knowledge of deep-water bivalve biodiversity in Chilean waters.
... Within the Phylum Mollusca, Bivalvia is the second-largest taxonomic class with about 10,000 existing species documented worldwide (Rahman et al. 2015). The diversity of bivalves includes 101 families and 1,380 genera with 9,620 species (Huber, 2015). Globally, annual total marine bivalve production is more than 15 million tons, with Asia alone producing more than 85% (FAO, 2017;Wijsman et al. 2019). ...
This study aims to describe the relationship between length and weight of the bivalves Donax cuneatus (Linnaeus, 1758) and Meretrix casta (Gmelin, 1791) along the Gulf of Mannar. A total of 1,791 individuals of two species were collected from October 2019 to December 2020. The length-weight relationship of both species has been estimated using the equation W = aLb. A common length-weight relationships, W = 0.0002 L2.8882 for D. cuneatus, and W = 0.1971 L2.3556 for M. casta were recorded. The results showed negative allometric growth in both the bivalve species. The coefficient of determination (r2) was 0.9426 for Donax cuneatus and 0.9628 for Meretrix casta. Condition factor was estimated to be less than one throughout the study period for D. cuneatus and for M. casta it ranged from 0.81 to 1.38. This study provides a mathematical equation of the relationship between length and weight, and the condition of both the species along the Gulf of Mannar, southeast coast of India.

The family Glauconomidae has few species, limited molecular data description, and insufficient research attention. The biodiversity of Glauconomidae within China deserves further exploration. In recent years, the taxonomic status of Glauconomidae has undergone changes, and some studies have found a close relationship between Glauconomidae and the family Cyrenidae based on molecular data, suggesting that Glauconomidae should be classified under the superfamily Cyrenoidea. However, both domestic and international research has mainly focused on only four species of Glauconomidae, indicating an urgent need for more species data support. Recently, 46 specimens of Glauconomidae were collected in the Yellow River Estuary in Dongying City of Shandong Province in China. Through a comparative analysis of shell morphology and molecular phylogenetic analysis of COI and 16S rRNA, two species of Glauconomidae was discovered. One is Glauconome angulata Reeve, 1844, and the other is a new species of Glauconomidae found in the Yellow River, named Glauconome huangheensis sp. nov. The G. huangheensis sp. nov. exhibits distinct differences in shell shape and shell color compared to other species of Glauconomidae, resembling G. angulata. There are also significant differences in shell color, shell sculpture, ligament size, and shell thickness. Furthermore, the molecular phylogenetic analysis based on COI and 16S rRNA genes supports the validity of G. huangheensis sp. nov. as a species. It indicates a close phylogenetic relationship with G. angulata, making them sister species. This study provides a redescription of the morphological characteristics of G. angulata and G. huangheensis sp. nov., laying the foundation for the morphological classification, biodiversity research, and conservation of Glauconomidae species.
The study was conducted as part of the Joint Vietnam–Russia Tropical Science and Technology Research Center’s project on indicator organisms in the marine environment of south-central Vietnam. The research focused on coastal areas with significant anthropogenic impacts, revealing that biological resources directly affect the livelihood and activities of coastal populations. These resources are dynamic and subject to both human and natural factors. The material from the soft-bottom zone was collected using a grab rake with a mesh bag at the end. Scuba diving equipment was used in areas with a hard substrate and mudflats. In addition, during sample collection, several mollusc specimens were acquired from fishermen who cought marine organisms in that lagoon. Comparing the results with previous studies on bivalve resources in the area, the Nha Phu Lagoon was found to harbour a wide range of economically valuable bivalve species. A total of twenty-seven bivalve species from thirteen families were identified, with the family Veneridae having the highest number of species (eight). The most abundant catches were from the families Ostreidae and Mytilidae, primarily consisting of Magallana gigas (Thunberg 1793) and Perna viridis (Linnaeus 1758), both cultured in the lagoon. Apart from their economic value, these two species also play crucial roles in the ecosystem by filtering water and retaining organic debris in the environment.
After revising the literature and consulting the pertinent virtual databases, we here list all Brazilian marine bivalves currently considered as valid and include data on their geographical and bathymetrical distribution. The list contains 516 indigenous and nine introduced species. Among the former, 461 species are autobranchs and 64 are protobranchs. They belong to 42 superfamilies, nine of them containing at least 20 species each; there are 77 families, twelve of which contain at least 15 species; most of these more speciose groups are typical from shallow waters (e.g., Tellinoidea and Veneroidea) and/or have been reviewed taxonomically (Nuculanoidea and Cuspidarioidea). There are 368 species which live exclusively on the continental shelf, 86 are only known from deep water and 68 species have a wide bathymetric distribution. More than half of the 368 continental-shelf species have a wide geographic distribution; 40 species are exclusive to the Brazilian province, the others also occur in the Caribbean and/or Argentine shelf waters; those from the Caribbean need more investigation. Important knowledge gaps remain for Brazilian Galeommatoidea and Nuculoidea, deep-sea species of Mytilidae, Teredinidae, and Arcidae; the Poromyidae, Limopsidae, Propeamussiidae, and Thyasiridae appear to be underrepresented. Compared to 29 world regional faunas of marine bivalves, the Brazilian diversity ranks in the ninth position.
From the Middle to Upper Pleistocene deposits on the seabed at upper bathyal depth in the southwestern part of Japan Sea, five species of Macoma (Macoma) were recovered with some cold-water species; Macoma (Macoma) lipara Dall, 1916a, M. (M.) scarlatoi Kafanov and Lutaenko, 1997, M. (M.) golikovi Scarlato and Kafanov, 1988, M. (M.) lama meridionalis Scarlato, 1981 and M. (M.) moesta (Deshayes, 1855). All species are living in Primorye, Hokkaido and northwards. It has been elucidated that
one of the characteristic species of the Omma-Manganji fauna, M. praetexta oinomikadoi Otuka, 1939 is a junior synonym of M. (M.) lipara Dall, 1919 living in Primorye via Bering Sea to California. This
Macoma-dominated assemblage was deposited in the glacial stage, MIS 6 (~185–135 ka) and similar to that of the Lower Pleistocene Hamada Formation in Aomori Prefecture.
Four species new to science were identified in the Tellinidae museum collections in the Marine Biological Museum of Chinese Academy of Sciences. Pinguitellina triquetra sp. nov., collected in 1981, has not previously been described or reported. It differs from other Pinguitellina species by its trigonal shape, rose-colored valve interior, and deep and wide pallial sinus, which is confluent with the pallial line. Pinguitellina protuberangla sp. nov. has a broad and deep dorsal corner, short and straight posterodorsal margin, comparatively large adductor scars, depressed and fragile shells, and deep socket at the anterior edge of the right valve. Pinguitellina minuta sp. nov. was previously misidentified as Arcopella casta in China. It is a new species based on its unique characteristics, which include small, fragile, inflated, translucent, and triangularly ovate-shaped shells with acuminated and convex umboes. As the first species described in China within the genus Abranda Iredale, 1924, Abranda xui sp. nov. has internal ligaments and thin, fragile, and translucent elliptical shells with fine radials on the surface. In this study, we reorganized the species currently contained in the two genera Pinguitellina and Abranda and created keys to the known species. We believe that numerous collected bivalve specimens have been overlooked in the South China Sea, and to date, mollusk has not been adequately sampled. Thus, further exploration and analysis are required to understand species diversity in this area.
Oyster habitats in the United Arab Emirates are highly diverse marine ecosystems with fascinating historical cultural and fisheries importance for pearls, but also for provisioning local people with food and materials for direct consumption and income. Their hard structure protects coastal areas and human populations and their assets, while their strong filtering activity promotes clean waters and healthy and productive marine ecosystems. Oyster habitats in the UAE occur on both the Arabian Gulf and Gulf of Oman coasts. They form oyster beds and oyster reefs and are distributed across coastal and offshore areas. These oyster habitats support hundreds of marine species that include valuable commercial species such as hamours (groupers), emperors (Lethrinidae), and snappers (Lutjanidae). The water quality in oyster ecosystems of Sharjah, Ajman and Umm al Quwain reflects good environmental conditions, yet the presence of microplastics in the sediment and oyster tissue evidence some pollution. Phytoplankton in these areas is diverse and includes several harmful algal bloom species. The current status and extent of oyster habitats in the UAE is known only for some emirates, but there is local scientific and management interest in addressing this gap for the conservation and restoration of these valuable habitats for the nation.
Based on morphological examination of rock-, shell-, and coral-boring bivalves in the marine genus Botula, Wilson and Tait (1984) concluded that this genus comprised a single Recent species, Botula fusca (Gmelin, 1791), with a pan-tropical distribution spanning the western Atlantic, Pacific, and Indian Oceans. Variation in shell colour, habitat, depth, and anatomy were determined to reflect variation within this one species. In a subsequent review of Recent and fossil Botula, Kleemann (2007) expressed doubts about a monotypic Botula given “striking morphological differences” between several described species, advocating for the study of soft tissues and application of molecular tools to help resolve species identities. Here, for the first time, we have undertaken a molecular phylogenetic approach to explore species-level relationships within the genus Botula. Our taxon sampling included freshly collected specimens from the Florida Keys National Marine Sanctuary in the context of ongoing research into bioeroding bivalves at reef restoration sites, in addition to previous collections from the western Atlantic, Pacific, and Indian Oceans available at the Florida Museum of Natural History and the Santa Barbara Museum of Natural History. Based on analyses of mitochondrial (COI and 16S rRNA) and nuclear (H3 and 28S rRNA) genes, the genus Botula appears to be monophyletic, with the contentious species currently classified as Leiosolenus kleemanni (Valentich-Scott, 2008) falling within Botula rather than Leiosolenus. High levels of sequence differentiation among samples in this study, including ones previously identified as “Botula silicula”, Botula cinnamomea, “Leiosolenus” kleemanni, and Botula fusca, supported them as distinct species. Our phylogenetic analyses also identified a potential cryptic species within western Atlantic Botula fusca. Increased knowledge of diversity within the genus Botula should lead to a more accurate understanding of the role of these bioeroding species in reef ecosystems.
Our research revealed 20 species of Bivalvia, 1 subspecies and 1 variety of the Sangzor River and its surrounding aquatic species belonging to 4 families and 5 genera. Of the species listed in the table: Euglesa hissarica, E. (Casertiana) obliquata, Odhneripisidium polytimeticum are more numerous. They are found in the amount of 1-4 m per 1 m2. The rest of the species are relatively rare. Euglesa (Cyclocalyx) gurvichi, Odhneripisidium terekense, O. (Kuiperipisidium) issykkulense were first discovered in the basin of the Sangzor river. These Bivalves are crenophils and pelolimnophils living in springs depending on their habitat. The length of the Sangzor River and the presence of all biotopes in which mollusks live, made the river a favorable habitat for mollusks. However, it should be noted that while all species occur in the river, they vary in density.
Marine lakes are bodies of seawater that are landlocked and maintain a subterranean connection to the surrounding sea. Here, we document the species diversity of benthic molluscs in 11 marine lakes in Raja Ampat, West Papua, Indonesia, using the roving diving survey method. We specifically tested for relationships between species richness and lake size and the degree of connection to the surrounding sea, and tested potential environmental drivers of community structure. We recorded 73 species, belonging to the classes Gastropoda (48 species, comprising 36 genera and 25 families), Bivalvia (24 species, consisting of 17 genera and 12 families), and Polyplacophora (one species). Molluscs from marine lakes are a subset of species also occurring in coral, seagrass, mangrove, and rocky shore habitats in the open sea. We found lake communities to mostly consist of grazers and filter feeders. The number of mollusc species significantly increased with increasing connection to the surrounding sea, but not with increasing surface area, indicating that dispersal potential may be the main driving force. Furthermore, we observed no significant influence of the environment on the variation in mollusc species composition among marine lakes. Still, we observed certain species to be exclusively present in either high or low-connected lakes, indicating a potential effect of environmental filtering. Marine lakes provide a unique ecosystem for diverse mollusc assemblages and as such should be protected.
The Thyasiridae is one of the species-richest families in the abyssal and hadal zones of the northwestern Pacific Ocean. Many thyasirid species dominate benthic communities in terms of abundance and play an important role in the functioning of deep-sea ecosystems. Most of the thyasirid species in the region are new to science and have not been described. Based on the material collected from 1954 to 2016 by seven deep-sea expeditions, three new species of Thyasiridae (Parathyasira coani sp. nov., P. pauli sp. nov., and Thyasira kharkovensis sp. nov.) are described from the abyssal and hadal zones (3210–7540 m depth) of the Sea of Okhotsk, the Bering Sea, as well as the Kuril-Kamchatka and Japan trenches. The new species are remarkable among their congeners due to the combination of the following characters: an obliquely-rhomboidal shell with a weak and shallow posterior sulcus and a large prodissoconch with sculpture of lamellated folds. Comparisons with related species are provided.
In this paper, a taxonomic review of the bivalves of the genus Cuspidaria Nardo, 1840 from the southern southwestern Atlantic is conducted. Specimens deposited in malacological collections and samples collected onboard the R/V Puerto Deseado off Mar del Plata (36S) and MPA Namuncur/Burdwood Bank area (54S), between 200 and 3,000 m depth, are the focus of this revision. The specimens were analyzed through conchological and anatomical features. The geographic and bathymetric distributions for each species are provided and possible factors determining biogeographic patterns are discussed. As a result, Cuspidaria infirma n. sp., Cuspidaria cancellata n. sp., Cuspidaria namuncura n. sp., and Cuspidaria cf. kerguelensis (Smith, 1885), are described. In addition, Cuspidaria exigua (Jeffreys, 1876), Cuspidaria bicarinata Jeffreys, 1882, Cuspidaria platensis (Smith, 1885), Cuspidaria tenella Smith, 1907, Cuspidaria infelix Thiele, 1912, and Cuspidaria barnardi Knudsen, 1970 are redescribed after the study of new specimens. Elliptic Fourier analyses were performed for each side of the shell to delimit species objectively using their shape. Results showed a clear differentiation on both valves among species. Cuspidaria bicarinata and Cuspidaria exigua, both North Atlantic species, were recorded for the first time in the southwestern Atlantic, and Cuspidaria infelix and Cuspidaria tenella, both Antarctic/sub-Antarctic species, expanded their distribution northwards. Two cluster analyses, for species and areas respectively, revealed a vertical zonation, separating species into two different groups highly corresponding to deep-sea water mass distributions.
Arthritica korniushini n. sp. is described from three groups of artesian mound springs in the southwestern part of the Lake Eyre Spring Supergroup. All other described species of Arthritica are oceanic or estuarine. The four previously described Australian species referrable to Arthritica are reviewed.
Using museum collections and historical literature the donacid genus Hecuba is revised. Three species are recognised, H. scortum (Linnaeus, 1758), H. pubescens (Linnaeus, 1758) and a new species described herein as H. reticulata Raven & Dekker. Each are described, figured and their geographical distributions are reviewed. Hecuba rosea Schumacher, 1817 is shown to be a junior synonym of Donax striatus Linnaeus, 1767, not of Donax vittatus Linnaeus, 1758.
The second part of the annotated and illustrated catalogue of species of the bivalve molluscan fauna of Jeju Island (Jeju-do) is based on original and literature data. The catalogue provides local distribution and taxonomic comments on bivalves and is supplemented with data on general distribution, habitats, and primary synonyms.
This part includes 142 species belonging to 36 families (Lucinidae through Poromyidae), with original photographs for 76 species. Nineteen species are reported as new for Jeju Island, 9 species as new for Korea: Vasticardium subrugosum (G.B. Sowerby II, 1839), Fragum loochooanum Kira, 1959, Montacutona japonica (Yokoyama, 1922), Pristipagia ojiensis (Tokunaga, 1906), Donax cuneatus L., 1758, Sunetta kirai Huber, 2010, Pitar inflatus (G.B. Sowerby II, 1851), Dosinia cf. orbiculata Dunker, 1877, Pelecyora corculum (Römer, 1870), and 6 species have been reported in literature but were not included in the first molluscan catalogue of Jeju by Noseworthy et al. (2007); in total, 25 species are added to the Jeju fauna in this part. Odd literature records are discussed. In all, 248
species and 58 families of marine bivalve mollusks are currently known in Jeju-do.
