“…This observation adds to the accumulating evidence that in contrast to Tompa’s (1984) suggestion that Achatinidae and their relatives do not produce spermatophores, these structures may be not uncommon in the Achatinoid clade of the Stylommatophora. Indeed, spermatophores have been reported in Achatinidae (Plummer 1975), Subulinidae (Baker 1945, Marcus 1968, Naggs 1994, Medeiros et al 2013) and Streptaxidae (de Winter et al 1999, Gerlach and van Bruggen 1999, de Winter and Vastenhout 2013, Rowson and Tattersfield 2013). …”

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.
