The male chelicera is unique, with a very long tooth on the retromarginal edge. The female has adelicate epigyne with large anterior atrium, unlike that in other thiratoscirtines. Etymology Specific name is derived from Africa, the continent where the species occurs.

Embolus base on prolateral side, wide proximally, forming lose loop distally ( Figs 82C, E , 83A ). Female Similar to male but lighter coloured.
