The original type locality is Caffraria, South Africa. The type specimens were collected by Wahlberg, who travelled primarily in eastern South Africa and northern Botswana (Usher 1972). Following recommendation 76 A.1.4. of the ICZN a new type locality is selected from within the range of the species. I hereby designate Doorndrai Dam Nature Reserve, Limpopo Province, South Africa, 24°11’S 028°26’E, which is close to Wahlberg’s route and in which the species has been recently collected, as type locality. Botswana, South Africa, Swaziland, Zimbabwe. Eastern Afromontane, Maputaland–Pondoland–Albany. <b>Lasiocnemus obscuripennis</b> (Loew, 1851), Figs 4, 23
