Menemerus natalis

Menemerus natalis is a medium-sized spider. The male has a dark brown, nearly black, flattened carapace that is ranges from 3.1 to 3.3 mm (0.12 to 0.13 in) in length and between 2.1 and 2.3 mm (0.08 and 0.09 in) in width. It has a scattering of white hairs that form lines on its edges and a stripe down the middle. Otherwise, it is covered in brown hairs. There are three white dots on the black eye field between the eyes. The spider's face, or clypeus, has white hairs. The spider has dark brown chelicerae, labium and maxilae. The underside of the carapace, or sternum is also dark brown. The spider's abdomen is between 2.0 and 2.3 mm (0.08 and 0.09 in) long and 2.0 and 2.3 mm (0.08 and 0.09 in) wide. It is russet-brown and covered in brown hairs with a lighter pattern on top and brown underneath. The spinnerets are dark and the legs brown. The spider has a long embolus, with a very fine conductor of nearly the same length. The tibia is small with a apophysis, or appendage, that is short and wide. The female has not been described. Spiders of the Menemerus genus are difficult to distinguish from each other. It is the copulatory organs of this species that are distinctive and enable it to be identified. The spider's embolus is particularly long and the tibia is small and narrower than the cymbium with a small tibial apophysis.

Menemerus spiders are found throughout Africa and Asia, and have been identified as far as Latin America. Menemerus natalis is endemic to South Africa. The holotype was found near Ashburton, KwaZulu-Natal, in 1991. Other examples have been seen in other areas of the country.
