This small genus of snakes in the Leptotyphlopinae subfamily is named after the country around which they center, Namibia. Most closely related to the type genus Leptotyphlops, these snakes are separated from their relatives by the usual presence of a crescent shaped scale, or shield, covering the cloaca (the other genera typically have heart-shaped or roughly triangular shields), high scale counts, and typically more slender profiles (Adalsteinsson et al. 2009.
