| Abstract |
Murex tubercularis Montagu, 1803, type species of the genus Cerithiopsis Forbes & Hanley, 1851, is reconsidered on the basis of its original material, other relevant specimens in museum collections, and pertinent literature and personal data. Since there is a general agreement on teleoconch characters, this work focuses on the protoconch. The latter is conical, of 4.15-4.75 moderately convex whorls, with subsutural and suprasutural spiral rows of granular microprotuberances. It results that a number of specimens with differently sculptured larval shells, hitherto identified as Cerithiopsis tubercularis, do not belong to it. Major issues of this study are 1) the type lot of Cerithiopsis tubercularis contains more than one taxon, 2) the identity of the syntype formerly designated lectotype of Cerithiopsis tubercularis is much doubtful, and 3) the existing name-bearing type of Cerithiopsis tubercularis is not in taxonomic accord with the prevailing usage of the name. Accordingly, a possible syntype in Natural History Museum (London) is selected as neotype of Cerithiopsis tubercularis. In this paper, the genus Cerithiopsis is intended rather strictly, to accommodate species with general protoconch characters basically conforming to those of the type species. The new genus Nanopsis, with type species Cerithiopsis nana Jeffreys, 1867, is proposed along with the new species Nanopsis buzzurroi and Nanopsis denticulate. |
