Philinopsis gigliolii (Tapparone Canefri, 1874) was described under the name Aglaja gigliolii based on preserved material from the Pacific coast of Japan, collected during an expedition of the Italian warship Magenta in 1864-1868. Currently, this species is considered a subjective synonym of P. speciosa Pease, 1860, described from Hawaii, despite t...

Retusa pertenuis is still formally considered a junior subjective synonym of Retusa obtusa, despite previous data indicating R. pertenuis and R. obtusa differ significantly in copulatory system morphology. In this paper, we study the species identity and population structure of R. pertenuis with an integrative approach combining morphological and m...

The composition of the nemertean fauna of the White Sea is summarized from the literature, collections of the Zoological Institute of the Russian Academy of Sciences and our own samples. According to published data, 52 species have been recorded for the White Sea. One of them (Tertastemma laminariae Uschakov, 1928) is recorded mistakenly, records o...

The biodiversity of Cephalaspidea (Gastropoda: Heterobranchia) is poorly studied, and novel findings often lead to revisions at different taxonomic levels. The family Philinidae has a distinct set of defining characters in the shell, copulatory apparatus, and gizzard morphology, but several species, considered part of the family, deviate from it si...

Philine malaquiasi Valdés, Cadien et Gosliner, 2016 is recorded from the Chukchi and Bering seas and from the southeastern coast of the Kamchatka Peninsula. This is the first record of the species for the Russian fauna. This species was initially considered as a member of the genus Philine Ascanius, 1772 (family Philinidae). In the present article,...

Although benthic fauna in the Pechora Sea (SE Barents Sea) is generally well-studied, information on the bottom communities in the shallows near islands and the mainland is still sparse. Shallow marine areas in the Pechora Sea serve as important feeding grounds for numerous benthophagous fish, waterfowl and marine mammals, including the Atlantic wa...

Our study focuses on the distribution and diversity of different cephalaspidean species collected from the Kuril-Kamchatka Trench (KKT) during the deep-sea expeditions KuramBioI (2012), SokhoBio (2015) and KuramBioII (2016). Our study recovered several undescribed taxa from different parts of the KKT and the adjacent abyssal plain, belonging to fou...

Meloscaphander grandis is a little-known species missing from databases and papers on taxonomic revision and phylogenetic analysis of Scaphandridae. This species is redescribed herein, based on the type specimen and specimens from the abyssal plain adjacent to the Kuril-Kamchatka Trench. A phylogenetic analysis of COI, 16S, and 28S markers show M....

Lineus species are the most abundant nemerteans that inhabit boreal regions of the Atlantic and Arctic Oceans and are the focus of many zoological studies. However, its taxonomy and species composition in Arctic areas remain poorly known. In this study, we performed an updated genetic analysis of nemerteans from the “Lineus ruber–viridis” complex,...
