Description. See Van Stalle (1986a: 97). The species is quite variable (see figs 90–106); in one male specimen from Popa Falls, Kavango, the periandrium has four apical spines (figs 100–106). Further studies are needed to clarify the taxonomic consequences of this morphological variation.

Distribution. “It occurs in the eastern highlands and probably in the major part of Africa south of the equatorial forest” ( Van Stalle 1986a: 100).
