Etymology. Named after the indigenous Venda tribe of the Limpopo Province; the species name is a noun in apposition.
Diagnosis. In the D. melana species group, D. venda sp. nov. shares with D. flava sp. nov., D. lotzi sp. nov. and D. melana the absence of dorsal abdominal markings. Among these species, females of D. venda sp. nov. have an epigyne structure most similar to D. lotzi sp. nov., particularly the shape of the anterior hood, but can be recognised by the considerably shorter ST II and the much longer ducts connecting ST II and ST I (compare Fig. 69 with Fig. 62). Males are most similar to D. tolkieni sp. nov. by the dorsal embolic prong being much larger than the ventral prong in prolateral view, but can be distinguished by the lack of abdominal markings (white dorsal spots present in D. tolkieni sp. nov.) and by the triangular shape of the RTA, which has a curved tip in D. tolkieni sp. nov. (compare Figs 155 and 145).

Spinnerets cream. Epigyne with deep anterior hood, anterior margin strongly convex, posterior margin slightly very slight convex, lateral ends tapering to narrow strips; lateral hoods curved, close to copulatory openings; ST I, ST II and connecting ducts orange-brown; ST II larger than ST I, ST II oval (Figs 69, 151, 152).
