ABSTRACT. – Morphometric analyses and molecular analyses based on the COI gene were performed on nominal taxa of the genus Neritina supposed to represent the same species, Neritina pulligera (Linnaeus, 1767). The results obtained have removed any doubt about the supposed synonymies. In particular, it appears that N. stumpffi Boettger, 1890 and N. knorri (Récluz, 1841), previously considered as sub-species, are valid separate species different from N. pulligera. Indeed, these two taxa are sympatric, morphologically differentiable and genetically distant by more than 11 % for the COI. The same applies to N. petitii (Récluz, 1841), N. canalis Sowerby, 1825, N. iris Mousson, 1849, N. asperulata (Récluz, 1843) and N. powisiana (Récluz, 1843), which have been confirmed as valid distinct species from N. pulligera. The Indo-Pacific distribution of N. stumpffi is proven, that of N. knorri is yet to be confirmed
