Range: Coastal South Africa, Eastern and Western Cape Provinces
A relatively well-known species in the genus, the Black or Cape threadsnake is a South African endemic, its range stretching across the entire southern coast (records from the rest of Africa correspond to other species, not the Black threadsnake). It can grow to 20 cm in length, with a very slender build overall. The head is only slightly broader than the neck with a broad rostral scale, and the tail is short and blunt, tipped in a short spine. Scale row count midbody is 14, 10 on the tail, middorsal scale count around 280. Color is solid dark brown to black, dorsally an ventrally. This species can be distinguished by its solid color and broad rostral scale.
Habitat: Primarily fynbos vegetation as well as savannahs and grasslands in termite nests or under debris.
Prey: small soft-bodied invertebrates such as termite eggs and larvae.
Lifespan and reproduction: lifespan unknown, likely under 10 years. Oviparous, lays 2-3 elongate ovular white eggs.
