| Abstract |
After an in-depth study of the original descriptions and of the subsequent records nowadays available, Trapania graeffei (Bergh, 1881) is here re-established as a valid species, distinct from the congeneric Atlantic T. fusca (Lafont, 1874). In particular, since all the Mediterranean records of T. fusca are non-congruent with the original description of this species by Lafont (1874) and on the contrary they match with the external morphology of T. graeffei described by Bergh (1881), we definitively propose that the latter species has to be considered valid and endemic to the Central Mediterranean basin. On this basis, the distribution of T. fusca is restricted to the type locality, the Arcachon basin (French Atlantic coasts), since to date the record of Lafont (1874) is the only one congruent with the morphology of this species. |
