Amphiesma khasiense, commonly known as the Khasi Hills keelback, is a species of colubrid snake endemic to southeastern Asia.[1]

Geographic range[edit]

It is found in parts of southern China (Tibet, Yunnan), eastern India (Assam), Thailand,[2][3] Laos, Myanmar, Cambodia, and Vietnam.[1]


It is a reddish-brown snake with a white transverse bar running across the supralabial scales.

The dorsal scales are in 19 rows, rather strongly keeled, except for the smooth outer row. The ventrals number 150-154, the subcaudals 80-100. The anal plate is divided.

Adults are about 60 cm (23½ in.) total length, of which about 19 cm (7½ in.) is tail.[4]


The Khasi Hills keelback's nutritional intake consists primarily of toads.
