Conservation status and threats: No known conservation threats over its broader range, though it is limited to a fairly narrow higher-elevation habitat profile.
Interesting facts: The Khasi Hills Keelback was a species once only known from a few remote hill locations in Northeast India, but was eventually found to be spread across China, Myanmar, and Laos as well. In 2009, Pauwels et al. published their findings that specimens in northern Thailand formerly referred to as the similar-looking Malayan Mountain Keelbacks (Amphiesma inas), were actually Khasi Hills Keelbacks. The species now known to inhabit many mountains in northern Thailand, while Malayan Mountain Keelbacks are restricted to southern Thailand and Malaysia.
