Abstract:
The occurrence of at least one species of Erhaia in Bhutan, viz. Erhaia wangchukisp. n., is confirmed by DNA sequencing. A second unnamed species from Bhutan, that might be congeneric, is known from only a single shell. According to the molecular analysis, E. wangchuki is most closely related to a still undescribed Erhaia species from China. These two species together with E. jianouensis and Akiyoshia kobayashii, both also from China, form a well supported clade. Awaiting additional molecular data, the apparent inconsistency regarding Erhaia versus Akiyoshia is not dealt with here. The extant true sister species of E. wangchuki could be among the four SE Himalayan species from Bhutan and Nepal that are classified with Erhaia on the basis of conchological data only.
