Diagnosis

This species is immediately identifiable by the appearance of the fore wings which are of normal shape, and uniformly fuscous, without dark patches or strong microtrichiae, in contrast to the elongate and chromatically modified fore wings in the other two species. An additional diagnostic character is the presence of an occipital pit, which is absent in the other two species. The mesosoma is correspondingly less longitudinally compressed, with the mesocutum and mesopleuron being more normal in proportions. The pronotum and occiput are glabrous without the long setae present in the other two species. The acetabular and mesopleural epicoxal sulci do not converge as in the other two species, and, correspondingly, the fore and mesocoxae are separated by more than one fore coxal width (separated by less than the fore coxal width in other two species) (van Noort et al. 2021).

Etymology

Named after the Karoo area wherein both main collection localities fall (van Noort et al. 2021).

Biology

Unknown.
