Abstract

Freshwater mussels are sensitive to habitat and water quality, revealing the fastest rates of human-mediated global extinction among aquatic animals. These animals are especially diverse in tropical Asia, the faunas of which are characterized by high levels of endemism. Here we describe four new species and four new subspecies of freshwater mussels from Myanmar. Leoparreysia whittenisp. nov., the smallest representative of this genus, was discovered from the Ayeyarwady and Chindwin rivers. Radiatula myitthanensissp. nov. and R. chindwinensissp. nov. were recorded from the Chindwin Basin, and R. mouhoti haungthayawensisssp. nov. has been discovered from the Haungthayaw River. Indochinella pugio has been revised with a description of three subspecies: I. pugio viridissimassp. nov. from the Sittaung, Bilin and Bago rivers, I. pugio daweiensisssp. nov. from the Dawei River, and I. pugio paradoxassp. nov. from the Haungthayaw River. Yaukthwa elongatulasp. nov., a peculiar species, conchologically resembling representatives of the genus Solenaia (Gonideinae) with ultra-elongated shell was found in the Chindwin Basin. Our records highlight that tropical Asia harbors numerous, but still overlooked local endemic lineages of freshwater bivalves, which may be on the brink of extinction due to the high anthropogenic and climate change impacts.
