Abstract

We present a new record of a little known tree snail Amphidromus sinensis (Benson) from the Similipal Biosphere Reserve in Odisha. It is the first record from the peninsular region of India and is remote from the previously known range. The distribution suggests either dispersal of the species through the Malayan region to northeast India, through Assam hills to Chotta-Nagpur plateau, to further Eastern Ghats, or a spread which took place during the Pleistocene, with the isolated population remaining in the region.

Key words
