New Records of Two Freshwater Gastropod Molluscs for Trinidad, West Indies

Ryan S. Mohammed, Mike G. Rutherford

Abstract


The freshwater molluscs of Trinidad have been studied since the 1860s. R.J.L. Guppy wrote many papers on the terrestrial and freshwater molluscs of Trinidad, culminating in his comprehensive list in 1893. In this he names nine species of freshwater gastropods. E.A. Smith, working at the same time, came up with ten species in his 1896 paper, although he did write that one of them was possibly a synonym of one of Guppy’s species. Workers since then have added a few more and by 2007 Maharaj and Alkins-Koo had listed 15 potential species from nine families: Ampullariidae, Ancylidae, Planorbidae, Thiaridae, Neritidae, Physidae, Lymnaeidae, Hydrobiidae and Pleuroceridae. However, several of the specimens found in this last study were not identified to species level. This note reports on one new record of an Ampullariidae and one new record of a Lymnaeidae.
