  • Title
    Erhaia Davis & Kuo (Gastropoda, Rissooidea, Amnicolidae) also in Bhutan
    Type
    Journal Article
    Description
    The occurrence of at least one species of Erhaia in Bhutan, viz. Erhaia wangchuki sp. 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 undescribedErhaia 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.

  • Title
    Gastropods in Bhutan, The genus Rahula (Pulmonata: Helicarionidae)
    Type
    Journal Article
    Description
    Two species of the poorly known genus Rahula are described as new to science from Bhutan. These species bridge the distributional gap that hitherto existed between Sikkim in the west and Arunachal Pradesh in the east. Additionally the taxa that are considered Rahula species in the literature are listed. On the basis of these data, the fragmentary distribution of the genus, from the E Himalaya southwards to Vietnam, Indonesia and Malaysia, is summarized.
