Abstract

This paper extends the range of distribution of Conta pectinata in Sille River, Brahmaputra drainage, East Siang District of Arunachal Pradesh and gives some information on its habitat and threats, which are still to be documented properly. Some brief additional characters are also added here. Our examination revealed that some morphological variations exists from originally described C. pectinata by having deep body at anus (10.3–11.9 vs. 7.5–9.4% SL); short dorsal-spine (length 15.7–20.8 vs. 20.9–24.0% SL), less number of serrae on anterior margin of dorsal-spine along the entire length (15–18 vs. 18–20) etc. The major threats identified are the frequent use of electrocution and the chemicals in the river during the winter season .
