Remarks: This species is currently only known from males. Now that a series of both sexes is available from Saudi Arabia (Najran, Alshurfa, 01–28.i.2015, H. A. Dawah deposited in NMWC), the female can be described. In the male the antenna is, with the exception of the arista, entirely yellow, whereas in the female the postpedicel is black on both surfaces on a field extending from the base of the arista to the lower apex. Furthermore, although in the male the ground colour of the fore leg is yellow throughout, any apparent darkening being due to compact tarsal setulae, in the female the fore leg is black with the exception of the coxa, trochanter, basal 1 / 2 of the femur and knee. The female tergite 8 ( Fig. 24 ) is anteriorly divided into the usual three lobes, which are almost equally long and their lines of separation are almost 1 / 2 as deep as the segment. The apices of the lobes are not perceptibly darkened and the usual pair of separated sclerites are so small as to be scarcely discernible.

Distribution: (Afrotropical): Botswana, Lesotho, Namibia *, Nigeria and South Africa; (Palaearctic): Saudi Arabia.
