Diagnosis.

This species has golden / yellow vibrissa, similar to that of Atherigona pulla ( Wiedemann, 1830) and Atherigona chrysohypene Muller, 2015 . It can be distinguished from A. pulla by the shape of the trifoliate process, with the median piece bent at a right-angle when viewed in profile (Fig. 4 b ) compared to a linear median piece in A. pulla . It can be distinguished from A. chrysohypene by the shape of the hypopygial prominence which is knoblike (Fig. 4 ) and with an apical emargination, compared to that of A. chrysohypene which is bilobate (Fig. 5 ).

Distribution.

Botswana, Lesotho (new record), Namibia, Nigeria, South Africa, Saudi Arabia.
