Common names: horseshoe pitviper.[3]

Trimeresurus strigatus is a venomous pitviper species found in southern India. No subspecies are currently recognized.[4]

Geographic range[edit]

Found in the hills of southern India, Trimeresurus strigatus is distributed in the Nilgiri, Anaimalai, Palni, Tinnevelly, and Shevaroy Hills of the Eastern Ghats at elevations of 3,000-6,000 ft (900-1,800 m) (M.A. Smith, 1943).

The type locality listed is "Cape of Good Hope?" and "Madras?" (Madras, India). The former must be a mistake.[1] Boulenger (1896) restricted the type locality to "Madras Presidency".[2]


Trimeresurus strigatus may be distinguished from other pit vipers of peninsular India based on the presence of small internasals, 21 rows of keeled dorsal scales at midbody, and a single row of scales between labials and suboculars.

The common name of the species is based on the presence of a pale buff horseshoe-shaped mark on the nape.

Of 12 snakes measured, the mean snout-vent length (SVL) was 24.4 ± 7.04 cm (9.6 ± 2.8 in), the tail length (tL) was 3.5 ± 0.8 cm (1.4 ± 0.3 in), and the weight was 172 ± 10.5 g (6 ± 0.4 oz).[citation needed]
