It is found in South Africa, where it is known only from the "Eastern Cape". It lives amongst "Adiantum" species and other ferns on rocky banks of streams where seepage maintains very limited growth of thallose liverworts and mosses in an otherwise hot and arid environment. The length of the forewings is about 2.5 mm for males 2.6 mm for females. The species is named after the semi-arid region in which

The dolerite of the Great Karoo did not penetrate these rocks, so Karoo Koppies are not seen in the Little Karoo. The Little Karoo contains two other geological features that give the landscape a special character. During the erosion of the African interior following the bulging of the continent during the massive lava outpourings that ended the Karoo sedimentation 180 million years ago, some of the eroded material was
