Male (habitus: Fig. 63View Figs 59–64)
Differs from female mainly as follows. Body length: 0.90–1.75 mm. Antenna with flagellum yellowishbrown to dark brown. Fu1 length 2.0–2.8 × width; combined length of pedicel plus flagellum 2.3–2.4 × as wide as head. Eye height about 2.10–2.35 × malar space. POL 2.7–3.6 × OOL.

D.R. Congo, Gabon, Gambia, Kenya, Malawi, South Africa, Tanzania, Togo, Uganda, Zimbabwe.
The species can be recognized mainly by the dull dorsal surface of the mesonotum, without any differentiated frenal area ( Fig. 60View Figs 59–64). One female from South Africa (NMPC), excluded from the type series, has both fore wings abruptly shortened beyond the parastigma, as if cut off (no trace of shortened venation), and the hind wings also shortened and very narrow. I do not include these character states in the description because this seems to be an exceptional case.
