Endemic to the Western Ghats, in Karnataka , Tamil nadu and Kerala states of South India, Trimeresurus strigatus is distributed in the montane forests and Shola grasslands of the Upper Nilgiri (Whitaker & Captain, 2004). Historically misidentified and misreported from extralimital localities from both the Western Ghats and the Eastern Ghats. Perhaps this is the species of pitviper confirmed from India to have the smallest geographic range of all. .
