Range: Coastal Peru south of Chepen

​

The Dark Blidnsnake is a species that, as far as I can ascertain, is known only from a couple of specimens collected for the type description in 1943. It is described as a small snake that may not much exceed 10 cm, with a slender cylindric build and small rounded head barely wider than the neck, and a short, stubby tail tipped in a small spine. Dorsal scale count is 400-420, scale row count 14 reduced to 10 caudally. Coloration is almost uniformly dark brown to blackish, with only an occasional lighter spot on the rostral scale and slightly lighter ventral tone. This species is distinguished from its relatives by this uniform coloration, small size, and a somewhat smaller rostral scale allowing the ocular to touch the nasal plates.

 

Habitat: details unknown, but the type region is Andes foothills adjacent to Atacama Desert, a very dry region likely to restrict fossorials like these to drainages.

 

Prey: likely small soft-bodied invertebrates such as ant and termite larvae.

 

Lifespan and reproduction: lifespan unknown, likely under 10 years. Oviparous.
