Based on the shell structure, anatomical The purpose of this paper was to revise the tax- and radular characters of seven species recorded from onomic composition of the genus Latisipho from the the Russian marine fauna and attributed to genera La- Russian seas, based on anatomical and conchologi- tisipho and Helicofusus, L. pharcidus is reduced to the cal characters of six mentioned species and the spe- junior synonym of L. hypolispus, whereas L. errones, cies, described within the other genus, but found L. jordani, L. georgianus, and H. luridus – to the being closer to Latisipho, Helicofusus luridus Goli- synonyms of L. hallii. kov in Golikov et Scarlato [1985]. There is a number of works containing descriptions of shells and so- metimes radulae of Latisipho [Golikov, Gulbin, In 1916, Dall described subgenus Latisipho wit- 1977; Bouchet, Warén, 1985; Kosuge, 1991; Oku- hin the genus Colus Röding, 1799, with the type tani, 2000], and the data on their ecology and dist- species Chrysodomus (Sipho) hypolispus. He noted ribution [Golikov, Sirenko, 1998; Golikov et al., that numerous species of Latisipho exist in the Be- 2001; Kantor, Sysoev, 2005]. Nevertheless, there ring Sea region, and are strongly contrasted with are no data on the head-foot and mantle morphology, typical Colus by their buccinoid form and strongly as well as the anatomy of digestive and reproductive recurved short canal [Dall, 1918].
