A new Mitridae species from Indonesia, Sumbawa Island, is described as Quasimitra yanseni sp. nov. It is compared with Q. propinqua (A. Adams, 1853), Q. stossieri (Herrmann, 2016) and Q. lamarckii (Deshayes, 1832).
A new Vexillum species from Indonesia, Sumbawa, is described. It is compared to the similar but smaller Vexillum lyratum (Lamarck, 1811).
It is argued that the recently introduced stromboid taxa Dolomena columba lorenzi Cossignani, 2020 and Lambis montorum Cossignani & Lorenz, 2020 are junior synonyms of respectively Dolomena columba (Lamarck, 1822) and Lambis scorpius scorpius (Linnaeus, 1758).
This paper introduces a new species of Dominus from Indonesia, Dominus vinki nov. sp., and is compared with the recently described Dolomena likuii Zhu, 2023 and other species in the genus. Dominus vinki nov. sp. differs from other members of the Dominus complex in morphological form and range. Dominus was erroneously subjugated under Dolomena by Ra...
The name Strombus bonellii Brongniart, 1823 was antedated by Mitra nodosa Borson, 1820 (Harzhauser & Kronenberg, 2013). Both specific epithets have been frequently used in older literature for the same extinct species, of which the current combination is Persististrombus nodosus (Borson, 1820). In contrast, I advocate that Mitra nodosa Borson, 1820...
A new species of the genus Ministrombus Bandel, 2007 is described from Australia (Queensland) and New Caledonia (Lifou) and compared with other species in this genus.
A population of Strombus taeniatus Quoy & Gaimard, 1834 is rediscovered from Indonesia. This species was reinstated as a valid species after a long period of hiding in synonymy of Laevistrombus canarium (Linnaeus, 1758) (Maxwell et al., 2019). Recently offered shells on an auction website match with the description and drawing in Quoy & Gaimard, 18...
BOOK REVIEW [translated from the original Dutch publication] THACH - New Shells of South Asia and Japan, Taiwan, China. With 1 new genus, 1 new subgenus and 123 new species and subspecies, including 77 new marine species, 41 new land species, 5 new freshwater species and 18 new bivalves.
The taxonomy of the family Strombidae Rafinesque, 1815 is presented composed from the following sources: WoRMS database (World Register of Marine Species) or MolluscaBase, Existing literature and personal understanding of the phylogeny of Strombidae. Key-literature is listed in a literature section. It is not a definite listing: new species are des...
88 Dekkers, A.M., 2022. The fossil Strombidae (Ga stropoda) from Vanuatu (= NouvellesHébrides) described by Abrard, 1947.-Basteria 86 (2): 88-95. Published 1 December 2022. Abstract The taxonomic status of the fossil Strombidae recorded by Abrard (1947) from Vanuatu (formerly New Hebrides) is re viewed and updated. One of the species is described h...
In this paper we discuss the dispersal of Naria turdus (Lamarck, 1810), a Red Sea and
Indian Ocean species, in the Dutch Antilles. The species was first discovered in the Dutch Antilles by the second author in July 2020 in the waters around Aruba, where it currently forms a thriving colony. The first author made a discovery of the species on the ne...
In 2015, a very thin-shelled, translucent bivalve in the family Limidae Rafinesque, 1815 was described as Acesta vitrina Poppe, Tagaro & Stahlschmidt, 2015 and coming from deep water from the Philippines. A new genus is proposed to accommodate this species based on its unique shellchar-acters: an oblique, rounded shape, very translucent, thin-walle...
This article on strombs is a snapshot of the current stromb taxonomy (as interpreted by
me, T.E.) and an attempt to present as complete a series of extant strombid images as possible. The article is written by Thomas Eichhorst and here published with special permission From Eichhorst.
This paper describes a new endemic species from the central Philippines, Lambis vertriesti n. sp. and this brings the total number of Lambis species to twelve. The news species can be differentiated form other Lambis by its unique morphology. The lectotypes for Lambis lambis (Linné, 1758) and Lambis millepeda (Linné, 1758) are also designated from...
The newly described species Quasimitra houarti Dharma, 2021 from Indonesia is found to be a junior synonym of Quasimitra stossieri (Herrmann, 2016).
This part of the Canarium (Canarium) urceus-complex (Linnaeus, 1758) review after Abbott’s revision (Abbott, 1960) revision examines material from the Andaman Sea. At present, material from that region has been synonymised under the name Canarium (Canarium) urceus (Linnaeus, 1758). Canarium (Canarium) andamanense new species is known from the Andam...
This part of the Canarium (Canarium) urceus (Linné, 1758) revision after Abbott (1960) revision examines the northwest Pacific specimens, which are currently synonymised under Canarium (Canarium) urceus (Linné, 1758). Canarium (Canarium) nipponium n. sp. is known from the Ryukyuan Subprovince, Mariana Islands and Palau. The new species differs from...
This part of the Canarium (Canarium) urceus (Linné, 1758) after Abbott (1960) revision examines the Australian species of that complex. Currently, there is one recognised species, Canarium (Canarium) orrae (Abbott, 1960), which is divided herein into two species, with the description of Canarium (Canarium) darwinense n. sp. from the Van Diemen Gulf...
Aberrations on the number of eyes and strombid notches, the evolution of the eyesight , the use of the anterior canal and other morphological adaptions to the shells of the family are discussed. Animals with 3 and 4 eyes instead of 2 eyes are reported just as shells with 2 strombid notches instead of one strombid notch. The use of the term 'siphona...
A definition for differing terminal taxa in nomenclature is needed to make them practically relevant. The International Commission of Zoological Nomenclature (1999) provides for two levels: species and subspecies. At present species and subspecies are used interchangeably and arbitrarily. We examine both concepts, with a focus on practical applicati...
Abbott (1960) was too conservative in his assessment of species delimitations. Here, we evaluate the taxonomy of the marine gastropod Laevistrombus canarium (Linnaeus, 1758), and determine that there are two other extant species within this genus that are very similar, of which one occurs in the northwest Pacific and the other in the eastemmost par...
The variability of Tectarius pagodus (Linnaeus, 1758) is reviewed. Based on morphological differences, a new species is described as Tectarius padmiae sp. nov. from southern Java and comments are made on the synonyms of T. pagodus. The new species has 14-16 knobs/spines on the body whorl while T. pagodus usually only has 9-12 knobs/spines. A furthe...
This revision of the genus Canarium Schumacher, 1817 after Abbott (1960) advances
our understanding of the phylogeny of Strombidae. Morphological characters were used to generate a phylogeny using maximum likelihood and including all of the recognised species. This resulted in the recognition of one tree, and within that tree the existing genera Ca...
Microphos, a new genus for a small photinoid species, is described based on conchological differences with Phos Montfort, 1810. Type species of this new genus is the also newly introduced Microphos palogai sp. nov., a species from the Philippines. It is compared with Phos miculus (Fraussen & Poppe, 2005).
A new species in the genus Rostellariella is described based on 3 recently collected shells from south east Java, Indonesia. Rostellariella turcki sp. nov. is compared with the fossil species Rostellariella sumatrensis Wissema, 1947. The fossil species Rostellariella perlonga (Koperberg, 1931) from Timor, Indonesia, is confirmed to be a valid speci...
basteria 84 (4-6): 131 A new species of Semiricinula, S. preturbinoides spec. nov. is described from the Langhian Middle Miocene of Java, Indonesia, as part of a series describing the assemblage found at Wonosari, and the presence of Taurasia striata (de Blainville, 1832) is recorded from these same beds.
This study introduces four new species within the Canarium urceus complex. Canarium daveyi nov. sp. and the sympatric C. geelvinkbaaiensis nov. sp. from the region surrounding Geelvink Bay in northeastern Indonesia, C. youngorum nov. sp. from the island of northeastern Papua New Guinea, and finally Canarium manintveldi nov. sp from the southern Sou...
Many valid species can hide buried within prior taxonomic revisions. These need to be examined before the taxonomist embarks on the challenging task of naming new taxa. In this study we reexamine the synonyms complied by Abbott (1960) under Canarium urceus (Linné, 1758), examining each taxon for morphological clarity and distinctiveness. After cons...
A new strombid genus (Spinatus gen. nov.) is described from the Miocene of Indonesia. Two new species of Spinatus from the middle and upper Miocene of Indonesia are described: S. echinatus spec. nov. and S. wonosariensis spec. nov. The former is selected as the type species of Spinatus. A third species, Strombus (Strombus) tjilonganensis Martin, 18...
A well preserved tonnoidean gastropod fauna is described from Wonosari, Gunung Kidul Regency, Special Region of Yogyakarta, Java, Indonesia. In Bursidae, the second Indo-Pacific species of Aquitanobursa is described. In Cassidae, new species of Cassis and Cypraecassis are described, as well as the oldest known member of the genus Casmaria, and the...
Strombus urceus Linné, 1758 is a gastropod species that is one of the most variable and well documented through the centuries. However, we found the present identity of Strombus urceus misleading. Abbott (1960) designated the type locality, and confirmed type specimen, based on the microfiche of the Uppsala University, Museum of Evolution Zoology S...
The phylogeny of the American Strombidae the genus Lobatus is limited to the extant Lobatus raninus and several fossil precursors, the genera Macrostrombus, Aliger and Titanostrombus are re-installed as valid genera. The genus Persististrombus which was used as a sink for a plethora of species, is limited to the extant Persististrombus granulatus,...
This paper presents an examination of the relationships between Dolomena, Doxander, Mirabilistrombus, Neodilatilabrum and Labiostrombus using character state analysis and maximum parsimony. Hypothesized relationships are presented through the introduction of definitions that bridge the understanding of the evolutionary relationships with the applie...
This preprint presents the results of an examination of the relationships between Dolomena, Doxander, Mirabilistrombus, Neodilatilabrum and Labiostrombus using character state analysis and maximum parsimony. Hypothesized relationships are presented through the introduction of definitions that bridge the understanding of the evolutionary relationshi...
Report on the Brown ridge in the southern part of the North Sea part II. A growth series of Trivia monacha (Da Costa, 1778) Summary. The foundation 'Duik de Noordzee Schoon' ('Clean the North Sea through Diving') organises the removal of fishing nets from shipwrecks. Some of these nets collected in 2016 on the Brown ridge were transferred to Scheve...
This paper addresses the taxonomy irregularity concerning Altivasum typicum Hedley, 1916 fide Dekkers and Maxwell, 2018 that has historically been synonymized under Altivasum flindersi Verco, 1914. We introduce the erection of Altivasum hedleyi n. sp. correcting this taxonomical conundrum that originated from the Hedley (1916) paper. Furthermore, t...
This paper defines a new crown clade Neostromboidea to separate the Strombidae, Rostellariidae, and Seraphsidae from their sister families Struthiolariidae and Aporrhaidae. There is significant value to understanding evolutionary processes within Stromboidea to recognise the universal similarity in the position of the eye on the end of peduncles an...
(in Dutch) - article about the shells found in discarded fishing nets from a clean-up action held in 2016 in the Dutch part of the North Sea, the Brown Bank.
A new species of Terebellum is published in Visaya. We present a proof print of the plate issued with the description.
A new species of Seraphsidae Gray, 1853 , Terebellum simoni n.sp. is described from the Phillipines
A new species of Serapsidae Gray, 1853 , Terebellum simoni n.sp. is described from the Philippines based on conchological differences with T. terebellum (Linnaeus, 1758) and especially the recently described T. hubrechti Poppe & Tagaro, 2016
Many Australian small molluscan taxa are often overlooked, falling by the wayside and therefore, and remaining relatively unknown to the wider collecting community. This paper redescribes and illustrates Retizafra intricata Hedley, 1912, a species that has not been illustrated within the literature for over a century. Many species are listed in dat...
Zootaxa 4555 (4): 491-506 https://www.mapress.com/j/zt/ Article 491 https://doi.org/10.11646/zootaxa.4555.4.2 http://zoobank.org/urn:lsid:zoobank. Abstract Here we evaluate the taxonomy of the marine gastropod genus Laevistrombus Abbott, 1960 and determine that there are five extant species within this genus, three of which occur in the southwest P...
This paper seeks to correct the erroneous taxonomy associated with the current
understanding of the Altivasum flindersi (Verco, 1914) complex based on type revision,
morphological differences and geographic separation. Structurally, there are three distinct species that can be differentiated, Altivasum flindersi (Verco, 1914), A. typicum Hedley, 19...
The genus Saginafusus Wenz., 1943 currently contains one species from northern Australia. This paper presents a second species form the Andaman Sea. This new species differs from Saginafusus pricei E.A. Smith, 1887 in shell morphology and geographical distribution, with S. pricei being restricted to the Timor Sea. The new species is periodically so...
It is proposed to limit the genus Hemifusus Swainson, 1840 to the larger deeper water species from the West Pacific (though not recorded in the Philippines) with up to >30 cm cream coloured shell with non-determined outer lip and predominantly spiral ribbing, and to place the smaller shallow subtidal species with a range from India to the West Paci...
This paper highlights a putative inter-generic Conomurex x Gibberulus hybrid from the Sodwana Bay area, North Natal, Republic of South Africa. Putative hybridisation in the Strombidae is becoming ever more recognised at the intra-generic level. Much rarer are the inter-generic hybrids. The new putative hybrid indicates that inter-generic hybridisat...
One of the problems with undertaking revisions within Strombidae Rafinesque, 1815 is the tendency for chaining within the genus Strombus Linne´, 1758. Strombus is often used taxonomically as a holder for confusing taxa acting in sensu lato (s.l.). This paper addresses one of the chaining issues with Strombus with the erection of Striatostrombus gen....
A new species of Mitridae, Domiporta valdacantamessae, is described from Dingo Beach, Queensland, Australia. The shell shows similarities with other Queensland Domiporta species: D. and D. praestantissima Röding 1798, however the new species can be differentiated based on the clathrate micro-sculpture. At present, this species is only known from Qu...
About the found of a freak shell at the farewell of the ZMA, Zoologisch Museum Amsterdam
Several times “Duik de Noordzee schoon” (‘Clean the North Sea through diving’) organised expeditions with divers to explore marine life in
the North Sea and raise attention for the need to protect it. During the expeditions divers also remove fishing nets from shipwrecks as these nets
are harmful for fishes and crabs if they get stuck in these. In...
A new species of Turbo Linnaeus, 1758 endemic to the
Red Sea is described as Turbo (Turbo) moolenbeeki spec.
nov. in honour of Robert G. Moolenbeek. This new
species was previously confused with the similar
Turbo petholatus Linnaeus, 1758.
A species of Conus (Pseudolilliconus) from the Philippines
is described as new to science and named C (P.)
molaerivus spec. nov. in honour of Robert G. Moolenbeek.
It has been found in shallow waters off Mactan,
Samar and Mindanao. It is compared to Conus
(Pseudolilliconus) traillii A. Adams, 1855, and similar
species and morphs.
Peristernia schepmani spec. nov. is described from the
Philippines. It is compared with Latirus lautus (Reeve, 1847),
another small fasciolarid species of the same ground colour,
with which it has been confused, and with Latirus melvilli
Schepman, 1911.
It is argued that the Philippine morph that is confused with Cancilla turneri Poppe, Tagaro & Salisbury, 2009 on the shell market is in fact an undescribed species in need of a proper name: Cancilla herrmanni sp. nov. is hereby suggested for it. The new species is compared with Cancilla turneri and some other species belonging to the genus Cancilla...
Three new species of Mitridae are described in this paper: Subcancilla ruberorbis n. sp. and Subcancilla bellulavaria n. sp. from the Philippines and Subcancilla zetema n. sp. from different Pacific locations.
http://www.conchbooks.de/?t=642&u=34228&bookgroup=&subgroup=
It is argued that the large Vexillum thus far offered on the shell market and included in recent literature as Vexillum tumidum (Reeve, 1844) from Vietnam has to be regarded as a new nominal taxon. The new species is named Vexillum vangemerti spec. nov. and is compared with the real Vexillum tumidum (Reeve, 1844) from Australia, Vexillum vulpecula...
Several specimens of a deep water Semicassls species were obtained from Australia. Based on conchological characteristics, this tumed out to be an undescribed species, which is herein described as Semicassis dougthorni sp. nov. It is compared with the most similar species Semicassis bisulcata (Schubert & Wagner, 1829) and Semicassis japonica (Reeve...
It is argued that the Philippine morph recently offered on the shell market and wrongly identified as Vexillum sitangkaianum Cate, 1968 in recent literature has to be regarded a new nominal taxon. The new species is named Vexillum croceorbis sp. nov. and is compared with the real Vexillum sitangkaianum Cate, 1968 and Vexillum vulpecula (Linnaeus, 1...
When examining Vexillum shells from Roxas, Philippines, a new species seemed to be present in the material, but a closer look revealed a dark colour form of Vexillum balteolatum (Reeve, 1844), which has also been found in other places in the Philippines.
Two new species of Columbellidae: Mitrella chinoi sp. nov. and Mitrella confusa sp. nov. are introduced as new to science. Both species originate from deep water in the central Philippines. They are compared with their closest congeners.
A fourth hybrid specimen between the supposed involved parent species Euprotomus bulla (Röding, 1798) and E. vomer (Röding, 1798), is reported here based on morphological characteristics. The set of shell characteristics of this hybrid is slightly different compared to the earlier reported hybrid specimens. The hybrid specimen originates :from New...
A new Costellarid, Vexillum (Costellaria) kathiewayae n. sp., is described from subtidal waters (10 to 30 meter depth) from different area in the Indo-Pacific. This new species has been confused with Vexillum (Costellaria) zelotypum of authors (non Reeve, 1845) and Vexillum (Costellaria) rusticum (Reeve, 1845). The shell and live animal is also com...
The genus Lambis is discussed. A new genus based on conchological differences is recognised for which the name Ophioglossolambis gen. nov. is introduced.
lt is argued that the western Australian morph mostly known under the name of Vexillum ( Costellaria) zebuense (Reeve, 1844) has to be regarded as a nominal taxon. The new species is named Vexillum (Costellaria) johnwattsi sp. nov. and thoroughly compared with Vexillum ( Costellaria) zebuense (Reeve, 1844), Vexillum ( Costellaria) dohrni (A. Adams,...
It is argued that the nominal taxon Strombus labiosus Wood, 1828 is a complex of at least two and possibly three species. Strombus labiosus, at present attributed to the genus Dolomena, is redescribed. Dolomena abbotti sp. nov. is described as new to science and thoroughly compared with Dolomena labiosa (Wood, 1828). The new species is known from T...
Abstract: A hybrid in the genus Ministrombus Bandel, 2007 is reported here for the first time. Based on shell characters, the supposed involved parent species are M. variabilis (Swainson, 1820) and M. minimus (Linnaeus, 1771). The hybrid specimen originates from the Philippines. The combination Ministrombus variabilis is a new combination, formerly...
A new nassarid species from deep water in Philippines and Japanese waters is described as Nassarius kooli n. sp.
It has a striking appearance with a deep channel along the suture and with a colour pattern of brown squarish blots.
Mitra (Mitra) labecula n. sp. is described from moderately deep water (150-400 m) off Bohol and Aliguay in the Philippines. This new species has been confused with M. (M.) subflava (kuroda & Habe in kuroda, Habe & Oyama, 1971) and M. (M.) salva Turner, 2001. In this article M. labecula is differentiated from these two sister species and is also com...
Mitra (Mitra) labecula n. sp. is described from moderately deep water (150-400 m) off Bohol and Aliguay in the Philippines. This new species has been confused with M. (M.) subflava (Kuroda & Habe in Kuroda, Habe & Oyama, 1971) and M. (M.) salva Turner, 2001. In this article M. labecula is differentiated from these two sister species and is also com...
It is a study derived from literature on the possible origin of the family Strombidae and genera as recognised in the family.
Important information for the reader : it was based on the author's thought at that time and it is a club issue of De Kreukel, an Amsterdam based club. Nevertheless , it is an intresting view. The author at that time was rat...
An attempt was made to give a revision of the Family Strombidae.
The genera Tethystrombus, Neodilatilabrum and Solidistrombus are described as new.
Important information: this is an early writing of the author and some mistakes were not excluded. It is a brave attempt made with very little experience in writing, but nevertheless intresting to read....
A new species of the family Babyloniidae is described from South Africa. The shell features clearly indicate that the new species belongs to the genus Zemiripsis Thiele, 1929
Vexillum maduranum spec. nov. is decribed from the Island Java, Indonesia. The species is compared with V. (V.) jukesii (A. Adams, 1853) , V (V.) formosense (Sowerby III, 1889), V. (V.) curviliratum (Sowerby II, 1874) and a third not yet described species, erroneously called V. (V.) weberi (Bartsch, 1918). The new species is probably an Indonesian...
A new species of the family Colubrariidae is described from the Pacific Ocean, from the South China Sea. The species is probably endemic to China, so far unknown to science. A striking new species from the Philippines is also described as new to science, unfortunately only based on the holotype.

There are many good papers on the diverse stage of the Central Paratethys, Oligocene-Middle Miocene depositional sequences of the Central Paratethys and their correlation with regional stages, the gastropod assemblages etc. I wonder is there a recommendation for papers concerning the region of the north Arabian Plate and its timing of the closure of the TS, its assemblages of gastropods and bivalves, in the Miocene? The stages of the closure? Think of Syria and its surroundings, the parts that stayed open the longest time ...
