Annotated checklist of the freshwater snails of Sabah (Malaysian Borneo)

Sabah, a Malaysian state at the northeastern tip of Borneo, is situated in one of the Earth’s biodiversity hotspots yet its freshwater gastropod diversity remains poorly known. We present an annotated checklist of the freshwater gastropods collected from Sabah, which have been deposited in the <i>BORNEENSIS </i>collection of the Institute for Tropical Biology and Conservation at Universiti Malaysia Sabah, Malaysia. We further provide a KMZ file, which acts as a repository of digital images and complete collection data of all examined material, so that it can be shared and adapted to facilitate future research.
