Hot! Millard’s Hump Nosed Pit Viper (මුකලන් තෙලිස්සා)


Mildly Venomous

Millard’s Hump Nosed Pit Viper (Hypnale nepa) is a venomous pitviper species found in Sri Lanka. Relatively small, they are distinguished by a strongly upturned snout. No subspecies are currently recognized.

Adults grow to a total length of 30–35 cm. According to Wall (1921), the maximum recorded lengths are for a male of 38.7 cm and a female of 38.1 cm. According to Deraniyagala (1955), the largest specimen in the Colombo museum was 39.2 cm in total length with a tail measuring 5.9 cm. In general, the tail is 13-18% of total body length. The body is moderately slender with a head that is conspicuously distinct from the neck.

This species is distinguished from H. hypnale by a snout that has a strongly upturned tip. This is due to an extended rostral scale, which is immediately followed by a raised wartlike hump covered with 7-14 very small scales. Also, the hemipenes have clearly visible spines.

The scalation includes 17 rows of dorsal scales at midbody that are weakly keeled or smooth, 124-142 ventral scales and 33-41 subcaudal scales.

The color pattern consists of a light brown to dark brown to pale olive ground color, flecked and mottled with darker tones. This is overlaid with a series of 17-26 dorsolateral suboval or subtriangular brown blotches that alternate or oppose each other middorsally. These blotches are 3-4 scales wide and extend down to the third scale row. The top of the head is brown and usually lacks any pattern except for a black postorbital stripe that extends to the neck.

Found in Sri Lanka throughout forested areas, from lowland rainforest to over 1,800 m altitude.
