Second antenna oblong-ovate, with small apical point. Rami of caudal furca as in ^. Ovisac short, not extending beyond end of 4th abdominal segment. Length.—5-6 mm. Colour.—Translucent. Locality.—Kaokoveld : N, of Kamanyab. Type in South African Museum. As regards the 2nd antenna cJ, this species resembles somewhat the East African lamellifer Th. and also sudanicus Daday, but the finger has no teeth or spinules on its anterior margin.
