Angustopila elevata (Thompson et Upatham, 1997) was originally described from northern Thailand. It is the most widespread species within the genus Angustopila Jochum, Slapnik et Páll-Gergely, 2014, as revealed by a recent revision. The distribution of this species extends from southern Thailand through northern Laos and northern Vietnam to the Guangxi Zhuang Autonomous Region in Southern China. Based on shells recently collected in India, conspecificity was established between A. milium (Benson, 1853) and A. elevata, syn. nov. Furthermore, A. milium is reported from Nepal for the first time. Angustopila milium thus becomes the most widespread species of this genus and one of the most widely distributed land-snail species in South and Southeast Asia.

In this paper, we revise the genera Chamalycaeus, Cycloryx and Dicharax of the Himalayas and Myanmar. Another aim of this work was to identify the 13 species of Alycaeinae collected on the Blue Mountain, Mizoram State, northeastern India. Out of the 13 species from the Blue Mountain, seven are new and are described here: Chamalycaeus mizoramensis Páll-Gergely & Aravind sp. nov., Chamalycaeus reflectus Páll-Gergely & Aravind sp. nov., Cycloryx rohiniae Páll-Gergely & Aravind sp. nov., Dicharax praeda Páll-Gergely & Aravind sp. nov., D. semivivus Páll-Gergely & Aravind sp. nov., D. umashaankeri Páll-Gergely & Aravind sp. nov., D. ganeshaiahi Páll-Gergely & Aravind sp. nov. Altogether, 109 species are recognized, and all are figured. Furthermore, 37 new synonyms are reported, 32 of which were described by Godwin-Austen.
