Wings in £ hyaline, only the base and hinder part of costal cell yellowish brownish to brownish; wings in $ like those of ^.-anisospilus, but with fainter spots and no indication of a spot on basal cross vein of fourth posterior cell; apical cross vein of discoidal cell relatively shorter, straight; first posterior cell tending to be less narrowed or not narrowed apically. Head with the interocular space relatively narrower, distinctly less than twice width of ocellar tubercle in $ and only a little more than twice width of tubercle in $. Legs without spinelets on outer or hinder face of middle femora and without any apical spines on hind ones above, the latter with only about 3 or 4 spines. Hypopygium of $ (text-fig. 190) differs from that of anisospilus in small details. Last sternite of $ also very similar From 5 <$<$ and 6 $$ in the South African Museum. Length of body: about 4 §-5 mm. Length of wing: about 4 J-5 mm. Locality: Moordenaars Karoo in the Laingsburg Div. (Mus. Exp., March 1937) (types).
