Observations on the trapdoor spider Ancylotrypa nigriceps (Purcell, 1902) (Araneae: Cyrtaucheniidae)

Ancylotrypa Simon, 1889 is a genus known from 43 species endemic to Africa, with 29 species known from South Africa. They are large ground-dwelling trapdoor spiders that live in burrows that are closed with a wafer lid. Although it is a large genus, little is still known about their general behaviour. The general morphology, behaviour and distribution, along with images of live specimens of the species Ancylotrypa nigriceps (Purcell, 1902) that is known from Gauteng and the Free State in South Africa are discussed.
