Key to the Nepalese Diplommatina View in CoL species

A key to 15 species of Diplommatina is provided. Two species of Diplommatina ( D. canarica and D. pachycheilus ) reported by Kuznetsov & Schileyko (1997) were excluded from the key because neither species were found in the present surveys and no Nepalese material was available to examine internal lamellae. Moreover, D. canarica is endemic in the Western Ghats ( Raheem et al. 2014).
