Distribution

Ancylotrypa brevicornis is known from three South African provinces: Gauteng, Limpopo, and North West. Type locality is Venterskroon in North West Province. The species occurs at elevations between 1120 and 1628 meters above sea level. [2]

Habitat and ecology

This species is a free-living ground dweller that lives in silk-lined burrows. In addition to constructing a thin wafer-lid trapdoor, these spiders use a hard, spherical plug made of soil particles held together by silk to close the burrow entrance. The species has been sampled from both Grassland and Savanna biomes. [2]

Description

Both males and females have been described for this species. [1]

Conservation

Listed as Least Concern on the South African Red List. The species is protected in Nylsvley Nature Reserve, where burrow-constructing behavior has been studied. [2]
