Three potentially new species of aquatic gastropods in the genus Fluviopupa (Family Taetidae) were collected during a biodiversity assessment of streams in Emalu, in the province of Nadroga-Navosa. The collections were made by MSc student Bindiya Rashni. Preliminary identification work suggests that these could be three species new to science and endemic to Fiji. Bindiya also carried out freshwater macroinvertebrate surveys in Kadavu which yielded a larval specimen from the family of aquatic insects known as Crambidae, which were previously unrecorded in Fiji. The larva is yet to be identified to genus or species level, but preliminary analysis reveals a relationship with members of the genus Hygraula, which is found in New Zealand.Three potentially new species of aquatic gastropods in the genus Fluviopupa (Family Taetidae) were collected during a biodiversity assessment of streams in Emalu, in the province of Nadroga-Navosa.
