Neaetha irreperta

The spider is small. The male has a brown carapace that is 1.2 mm (0.047 in) long and 1.1 mm (0.043 in) wide, broad and quick high, particularly to the rear. It is very hairy, with brown bristles along the back eye field and light grey hairs covering the remainder. The rounded abdomen is between 1.1 and 1.2 mm (0.043 and 0.047 in) long and 0.9 to 1.1 mm (0.035 to 0.043 in) wide and is a deep red-brown with grey and brown hairs. An indistinct yellow-grey pattern is just about visible. The clypeus is low and the chelicerae dark brown, with one forward and two rear teeth. The rearmost spinnerets are lighter than the ones towards the front. The legs are stripy. The palpal bulb is brown and rounded with a long embolus. The female is slightly larger than the male, but has similar colouration. The carapace measures between 1.3 and 1.4 mm (0.051 and 0.055 in) long and 1.3 mm (0.051 in) wide while the abdomen is 1.5 mm (0.059 in) long and 1.3 mm (0.051 in) wide. The carapace has a thin black line along its edges and there are white scales on the eye field. The pattern on the abdomen is clearer, with the grey lines and marks easier to distinguish. It is covered with white and black hairs. The pedipalps are yellow. The epigyne is sclerotized and has a central pocket. The wide copulatory openings lead to broad and curved seminal ducts and oval spermathecae. …

Neaetha irreperta lives in South Africa and Tanzania. The male holotype was found in the Mkomazi National Park in 1994. It was subsequently observed in South Africa, initially in the Jubaweni Game Reserve in Limpopo, and then in the Ndumo Game Reserve in KwaZulu-Natal. It lives in savannah.
