Craspedocephalus macrolepis, commonly known as the large-scaled pit viper, is a venomous pitviper species endemic to the Southern Western Ghats of South India.

[6] It is found in the mountains of southern Western Ghats south of Palakkad Gap, in the Indian states of Kerala and Tamil Nadu.

[8] The type locality is listed as "Anamalai hills (Tamil Nadu State, southwestern India)".

An even number of dorsal scale rows is frequently found in this species, even though it is uncommon in snakes in general.

Based on these characters, and its Western Ghats distribution, Malhotra and Thorpe (2004) resurrected the genus Peltopelor Günther, 1864 for this species.

[10] Craspedocephalus macrolepis is a slow-moving, arboreal, nocturnal snake that prefers rainforests, and is also found in tea, coffee and cardamom plantations.
