Boiga dightoni, commonly known as Dighton's catsnake, the Pirmad cat snake, and the Travancore cat snake,[3][4] is a species of rear-fanged mildly venomous snake in the family Colubridae. The species is endemic to the Western Ghats of India.
Etymology
The common name, Pirmad cat snake, refers to Peermade (also spelled Peermad, Pirmaad, Pirmed, and Pirmedu), a place in Kerala, India, elevation 3,300 feet (1,006 m).
The specific name or epithet, dightoni, is in honor of tea planter S.M. Dighton, the collector of the holotype specimen.[4]
Geographic range
In India B. dightoni is found in the Ponmudi Hills and Travancore Hills of Kerala State, and in the Anaimalai Hills and Palni Hills of western Tamil Nadu State.[3]

B. dightoni is pale reddish-brown dorsally, with a series of salmon-red blotches. Its head is pale brown with minute blackish dots. Ventrally, it is yellowish, finely-dotted with brown. The outer ends of the ventral scales are salmon-pink. It is medium-sized, adults attaining a total length (including tail) of 1.1 m (3.6 feet).[5]
Behavior
Habitat

B. dightoni preys on lizards, including Calotes versicolor.[3]

Venom
Although rear-fanged and possessing a mild venom, B. dightoni is not considered dangerous to humans, mainly due to its small size.[3]
