Abstract

The species diversity of freshwater crabs of Bangladesh is poorly known. In this study, Acanthopotamon fungosum (Alcock, 1909) and Maydelliathelphusa edentula (Alcock, 1909) are reported as new records from Bangladesh. The two species were identified through morphology and molecular phylogeny based on 16S rDNA gene sequences. Herein, diagnostic characters of both species are provided respective to close congeners. There is concern over the conservation status of A. fungosum due to its narrow distributional range. In addition, an updated checklist and a key to the freshwater crabs of Bangladesh are provided.
