Abstract

Shells of the genera Metalycaeus and Dicharax from Bhutan are identified or described as representing new species. For Metalycaeus 6 species are recognized, 4 of which are known from Bhutan only and considered new to science, viz. M. geduensis E. Gittenberger & Sherub, spec. nov., M. karmademaae E. Gittenberger, Choki Gyeltshen & Kezang Tobgay, spec. nov. M. posteriobulbus E. Gittenberger & Sherub, spec. nov. and M. umbidistinctus E. Gittenberger & Choki Gyeltshen, spec. nov. In the more speciose genus Dicharax 16 species are classified, 12 of which as endemic and new to science, viz. D. aspidentatus E. Gittenberger, Choki Gyeltshen & Sherub, spec. nov., D. sajodentatus E. Gittenberger & Choki Gyeltshen, spec. nov., D. zhemdentatus E. Gittenberger & Choki Gyeltshen, spec. nov., D. umbiclausus E. Gittenberger, Choki Gyeltshen & Kezang Tobgay, spec. nov., D. trashidentatus E. Gittenberger, Choki Gyeltshen & Kezang Tobgay, spec. nov., D. vitreus E. Gittenberger & Kezang Tobgay, spec. nov., D. crassipalatum E. Gittenberger & Sherub, spec. nov., D. bhucarinatus E. Gittenberger & Sherub, spec. nov., D. bhudepressus E. Gittenberger, Choki Gyeltshen & Kezang Tobgay, spec. nov., D. bjiminaensis E. Gittenberger & Choki Gyeltshen, spec. nov., D. vanderbijli E. Gittenberger & Choki Gyeltshen, spec. nov., D. lunabulbus E. Gittenberger, Choki Gyeltshen & Kezang Tobgay, spec. nov. An identification key is provided for all Bhutanese Metalycaeus and Dicharax species.

Abstract

Samples of the genera Dioryx and Cycloryx from Bhutan are identified or described as new species. Next to the wide­spread D. urnula, 7 species of Cycloryx are recognized, 4 of which are endemic to Bhutan and new to science, viz. C. pemaledai Gittenberger & Sherub, spec. nov., C. globhu­tanus Gittenberger & Sherub, spec. nov., C. haumbiclausus Gittenberger & Gyeltshen, spec. nov., and C. sajumbiclausus Gittenberger & Gyeltshen, spec. nov. An identification key is provided for Cycloryx species. Cycloryx summus (Godwin-Austen, 1914), which was described from “Rechila Peak, Western Bhutan”, is not accepted as a Bhutanese species since its type locality is most probably in West Bengal, out­side the present borders of Bhutan.
