Atherigona decempilosa Dike, 1989

Fig. 25

Atherigona decempilosa Dike, 1989 b: 76 , figs 8–10.

Diagnosis: This species can be distinguished from others by its infuscated frontal vitta, antennae and palpi in combination with its legs having some degree of infuscation on all segments. The trifoliate process and hypopygial prominence appearing as in the redescription below and Fig. 25 .

Redescription: Upon inspection of the Holotype, I found that the figures for the hypopygial prominence used in Dike (1989 a, 1989 b) were incorrect and illustrated an entirely different shape, differing from the holotype material in that the hypopygial prominence was figured as plain knoblike, where in reality it is knoblike with a pair of lateral anteriorly projecting processes. The hood of the trifoliate process was also illustrated as simplified and not figured as well-developed and without an emargination at its posteroventral edge.

Type material examined: Holotype ♂: ‘ KwaZulu­Natal: Giants Castle Res. Natal Drakensberg, S. Africa . 5800ft. [1768 m] B. & P. Stuckenberg, 18–23 Sept. 1961 ’ ( NMSA; Type no. 1724).
