Abstract

Eleven species of Glessulinae belonging to the genera Glessula Martens, 1860 (three species) and Rishetia Godwin-Austen, 1920 (eight species) are reported from Nepal, six of which are new to science and are described here, viz., G. tamakoshi Budha & Backeljau, sp. n., R. kathmandica Budha & Backeljau, sp. n., R. nagarjunensis Budha & Naggs, sp. n., R. rishikeshi Budha & Naggs, sp. n., R. subulata Budha & Naggs and R. tribhuvana Budha, sp. n. and two are new records for Nepal viz. G. cf. hebetata and R. cf. mastersi. The relation between the shell height-width ratio and the structure of the proximal part of the male reproductive organs in Glessulinae is explored. Illustrations and a key for the identification of the Nepalese Glessulinae are provided, including the first record of a spermatophore in Rishetia.
