Pseudodon is a genus of bivalvia from the Unionidae family of freshwater mussels native to East and Southeast Asia. There are 12 recognized species.[1] Their life cycle is thought to be akin to other Unionids, parasitizing fish in order to disperse. They are locally consumed and provide raw materials for jewelry, cosmetics, and medicine.[2]
The taxon was described by John Gould from his findings at the Salween River Basin in British Burma, initially described as a subgenus of Anodon. Gould included two species in the taxon, the type species Anodon inoscularis and Anodon salweniana.[3]
The shell of Pseudodon is rather thick and shaped like an elongated oval, with a slightly convex crown on the upper valve shifted toward the rear.[4] The surface, although most often smooth, is crossed by deep transverse furrows in some species. The hinge teeth are high, thick, and rounded at the apices.[5]
Range
The distribution of the genus is limited to East and Southeast Asia, mainly the Yangtze River Basin and Myanmar.[5] The species Pseudodon inoscularis is also found in Thailand, Cambodia, and southern Vietnam, while the species Pseudodon resupinatus is endemic to northern Vietnam,[6] and the species Pseudodon vondembuschianus is found in Indonesia and Indochina.[2]
