Barnes' Cat Snake

Boiga barnesii

''Boiga barnesii'' is a species of cat snake found in Sri Lanka known as the Barnes' Cat Snake in English and ''panduru mapila-පදුරු මාපිලා'' in Sinhala. It is a member of the snake family Colubridae. It is endemic to Sri Lanka and is distributed in the lowlands and midlands up to ~600m above sea level, with known localities include Matale, Kandy, Gannoruwa, Gampola, Ambagamuwa, Balangoda, Labugama and Sinharaja Rain Forest. Barnes' cat snake is mainly a forest-dwelling species but may occasionally be found in human habitats. It is the smallest cat snake in Sri Lanka and grows up to a maximum of 600 mm in snout-vent length. Being a nocturnal and an arboreal hunter, it mainly feeds on agamid lizards and geckos. The day time is usually spent inside a tree hole or a crevice. It’s a very timid and a mildly venomous snake and rarely attempts to bite.
Tiny baby Barnes' Cat Snake ready for a fight A lot of the cat snakes will coil the front part of their bodies like this. I've usually seen this as a defensive posture, though in this case the little (between 4 and 5 inches long) snake was already in this position when I first saw it. Maybe it saw me before I saw it though. Boiga barnesii,Geotagged,Sri Lanka,Summer

Naming

The specific name, ''barnesii'', is in honor of Richard Hawksworth Barnes , who collected specimens in Ceylon for the British Museum , including the type specimen of this species.

Defense

Although ''panduru mapila'' is only mildly venomous, and bites on humans produce only local symptoms, there is a common misconception in Sri Lanka that all ''mapilas-මාපිලා'' are highly venomous and could kill a human with its venom. This misconception may be because the name ''mapila'' is used to refer to different species in different parts of the island. Due to differences in local knowledge and nomenclature, the krait species found in Sri Lanka are also referred to or misidentified as ''mapila''. Both krait species mentioned are highly venomous.
