Habitat

The species occurs in Savanna biomes and constructs circular webs under stones. The web is attached to the stone's underside and hangs like a veil, with the entrance positioned on the northern side.

Description

Tyrotama bicava is known from both sexes. Like other members of the genus Tyrotama, it exhibits the characteristic shorter legs compared to Hersilia species.

Conservation

Tyrotama bicava is listed as Least Concern by the South African National Biodiversity Institute due to its wide distribution range across multiple African countries, despite its limited known occurrence in South Africa. No significant threats have been identified.

Taxonomy

The species was originally described by Smithers in 1945 as Tama bicava from Namibia. Foord & Dippenaar-Schoeman transferred it to the genus Tyrotama.
