Terrestrial snails diversity of Lower Dibang Valley, Arunachal Pradesh

Abstract

A total of 75 species belonging to 36 genera, 14 families under 3 orders from 256 specimens were reported during the study from the Lower Dibang Valley district of Arunachal Pradesh. Surveys were conducted in various parts of the district under different institutional projects conducted during 2015 and 2016. Snails were hand-picked and randomly preserved in 70% Ethanol. Order Stylommatophora with 49 species under 10 families and 25 genera was the most common group, followed by Architaenioglossa with 26 species under 3families and 10 genera. The present study is the first of its kind under this group of animals since no work has been done on the comprehensive taxonomy of terrestrial mollusca of the district.
