Material examined. Holotype male. TANZANIA: Mkomazi Game Reserve , 5 km North of Ibaya, 9–10.VIII.1993, pitfalls, short grass and bushes, Ritchie M. and Makusi R. ( MRAC 215708 View Materials ).

Diagnosis. The male of this species is recognized by the broad, curved retrolateral tibial apophysis with a large seta pointing outwards and the long embolus with broad base, its tip supported by the broad MA with a short triangular prong. In M. violaceus the MA has two short triangular prongs whereas in M. rwegura the tip is rounded.

Etymology. The specific name “ aurantioviolaceus ”, refers to the colour of the carapace and the abdomen respectively orange and sepia.

Eyes: ocular area dark, AME 0.08, ALE 0.06, PME 0.06, PLE 0.06 PME-PME 0.08; AME almost touching. Clypeus with tuft of bristles. Chelicerae yellowish orange. Sternum pale orange, margin darker orange. Legs orange, with short hairs; spineless. Abdomen, Oval; dorsum sepia with some poorly marked pale chevrons; venter pale yellow. Palp (figs 1A, B): cymbium with distal spine and sub-distal row of four modified setae; tibia with retrolateral apophysis relatively broad, curved, rounded at the tip, and very broad ventral apophysis with broadly rounded tip and large spine pointing outwards; embolus originating on posterior part of tegulum, its base pointing forward to distal tip of tegulum, broadly curved towards MA.
