The genus Sibogasyrinx has to date included only four species of rare deep-water Conoidea, each known from few specimens. In shell characters it strongly resembles three distantly-related genera, two of which, Comitas and Leucosyrinx, belong to a different family, the Pseudomelatomidae. A molecular phylogenetic analysis of a large amount of materia...

A taxonomic revision and redescription of the genus Eurymesosa Breuning, 1938 are presented, including a key to species. Three of the five currently accepted species are considered valid: Eurymesosa ventralis (Pascoe, 1865), Eurymesosa allapsa (Pascoe, 1866) and Eurymesosa ziranzhiyi Yamasako & Lin, 2016. Three junior synonyms are proposed for E. v...
We present a revision of the genus Parahyparrhenia for India including detailed description of the two endemic species i.e. P. bellariensis and P. khannae, with photo plates. Epitypification of P. bellariensis is done to facilitate correct identification. The present circumscription of the genus is also discussed with respect to irregular morpholog...
As a part of a general revision of the South American Dendryphantini, type materials of several taxa have been examined. Certain inconsistencies regarding the species composition of the genus Naubolus Simon, 1901 have been observed. In order to resolve these inconsistencies the type series of two Naubolus species have been studied. The unknown male...
Two new synonyms in the subfamily Theridiinae Sundevall, 1833 (Araneae, Theridiidae) are reported. Theridion hui Zhu, 1998 is proposed as a junior synonym of Theridion innocuum Thorell, 1875, and Theridion qingzangense Hu, 2001 is proposed as a junior synonym of Phylloneta impressa (L.

A new genus of the millipede family Pachybolidae from Southeast Asia is described: Macrurobolus gen. nov. , with Spirobolus macrurus Pocock, 1893 as type species. This latter species is DNA barcoded (COI) and redescribed based on male morphological characters, which hitherto were unknown. The new genus differs from other pachybolid genera by having...

... Spiral sculpture of distinct cords on and below shoulder. Taxonomic remarks The shell outline of the new species resembles some species of Leucosyrinx (Pseu-domelatomidae), particularly Leucosyrinx verrillii, but it differs from that species in its smaller size, less numerous shoulder nodules and radular morphology (Kantor & Puillandre, 2021). Diagnosis Shell broadly fusiform, with rather short spire, thin, light greyish white. ...
In this catalogue, 46 species of gastropods collected by the IN2021_V04 and IN2022_V08 expeditions to the Australian Christmas Island and Cocos (Keeling) Islands Territories are described and illustrated.
... The use of molecular data to perform integrative taxonomy is now routinely employed in the literature (e.g., Kantor & Puillandre 2021;Šobáňová & Ďuriš 2021;Vaga et al. 2021), but surprisingly rarely for sea spiders, except for the Southern Ocean and Australia (Arango et al. 2011;Dietz et al. 2015aDietz et al. , 2015bDömel et al. 2015Dömel et al. , 2017Dömel et al. , 2019Dömel et al. , 2020Soler-Membrives et al. 2017;Brenneis et al. 2020). However, this is a paramount tool to overcome the complexity of sea spider taxonomy, which enabled us to delimit additional species compared to our preparative paper (Sabroux et al. 2019b) and to discriminate several closely related species: Eurycyde kaiouti sp. ...
This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.

... As studying species with distribution outside Australian waters was beyond the scope of this study, the testing of 10 PSHs (i.e., those with a letter suffix) out of a total of 18 was not attempted. These PSHs and S1 also included samples whose taxonomic characterisation has been provided in previous studies (e.g., Kantor et al. 2016;Kantor et al. 2018;Kantor and Puillandre 2021). The remaining seven PSHs (A1, A2, C1, C2, L1-3) satisfied the conditions described in the methodological section for conversion to SSHs. ...
... The conversion of S1 to SSH was rejected on the grounds of one of the constituent samples (AMS C.519344) exhibiting significant genetic distance (4.6%) and possessing a remarkably different shell ( Figure 5A) when compared to the other two samples of S1. This is in agreement with the conclusion of Kantor and Puillandre (2021), where two different species were recognised for the specimens of the two distinct S1 clades (Figure 3). ...
A series of deep-sea expeditions in southeastern Australia has produced a considerable amount of conoidean (Gastropoda: Neogastropoda) material suitable for molecular and morpho-anatomical study. Previous and ongoing studies have revealed the Raphitomidae to
be particularly diverse in the deep waters of this region. Here, we continue our conoidean investigation, focussing on the genera Comispira (Cochlespiridae) and Leucosyrinx (Pseudomelatomidae). We subjected two cytochrome oxidase subunit DNA sequence datasets of Conoidea to Automatic Barcode Gap Discovery (ABGD), which recognised a total of 18 primary species hypotheses (PSHs) among our target genera as well as from the
cochlespirid genera Sibogasyrinx and Aforia. Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges (conducted for PSHs of Australian waters), eight of these PSHs were converted to secondary species
hypotheses (SSHs). Of these, three SSHs (one Comispira species, two Leucosyrinx spp.) were recognised as new to science and their full systematic descriptions are provided herein. While we discuss the relatively low diversity of Cochlespiridae compared to most conoidean families, two Comispira species and one species of Aforia are here recorded for the first time
from Australian waters.
