Description. ♀. Fully winged; body length 2.4–3.1 mm. Head black, except mandible yellow (with teeth brown); an- tenna brown, except scape and pedicel testaceous (occasionally also flagellomeres 1 or 1–3 testaceous); occasionally antenna totally testaceous; mesosoma and metasoma black; tegula testaceous; legs brown, except tarsi testaceous; occasionally legs totally testaceous. Antenna clavate; antennomeres in following proportions: 17:4:5:5:5:6:6:6:6:9. Head shiny, setose, granulate and completely reticulate rugose; frontal line present; frons without lateral keels; occipital carina complete; POL = 8; OL = 5; OOL = 7; OPL = 5; TL = 4. Pronotum rugose and granulate; posterior surface much shorter than mesoscutum (4:14); pronotal tubercle reaching tegula. Mesoscutum shiny, granulate, with strong or slight, more or less numerous, irregular keels. Notauli absent. Mesoscutellum shiny, smooth, slightly punctate. Metanotum strongly rugose. Mesopleuron and metapleuron granulate, with numerous transverse keels. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose, slightly shorter than mesoscutellum + metanotum (12:13); propodeal declivity granulate and with numerous transverse keels, without longitudinal keels (in specimen from South Africa, 34°16.481’S 19°01.033’E, propodeal declivity granulate, without transverse and longitudinal keels). Forewing usually with two dark transverse bands, occasionally with one band (in specimens from Uganda and South Africa, 34°16.481’S 19°01.033’E); distal part of 2r-rs&Rs vein much shorter than proximal part (2:8). Protarsomere 1 much longer than 4 (8:3); protarsomere 4 approximately 0.5 × as long as basal part of 5, produced into hook. Enlarged claw ( Fig. 50E ) with proximal prominence bearing onelong bristle. Protarsomere 5 ( Fig. 50E ) with 10 lamellae. Tibial spurs 1/1/2.

♂. Fully winged; body length 2.2–2.5 mm. Head black (rarely brown), except mandible testaceous (with teeth brown); antenna brown, except scape and pedicel testaceous; mesosoma and metasoma black (rarely brown); tegula testaceous; legs yellow, except metacoxa, club of metafemur, metatibia brown (in specimen from Kenya, 4.32664°S 39.52462°E, legs totally testaceous). Antenna filiform; antennomeres of specimen from Madagascar, 21°13.57’S 47°22.19’E, in following proportions: 7:3.5:4:4:4:4:4:4:4:7. Head dull, granulate and slightly reticulate rugose (in specimen from South Africa, 32°43’S 26°35’E, head granulate and strongly reticulate rugose); frontal line usually incomplete (in specimen from Tanzania, Mkomazi Game Reserve , frontal line complete); frons usually without lateral keels near orbits and directed towards antennal toruli (present in specimen from Tanzania, Mkomazi Game Reserve ); occipital carina complete; POL = 6; OL = 3; OOL = 5; OPL = 4; TL = 3. Vertex without two oblique keels connecting lateral ocelli to occipital carina. Mesoscutum dull, usually granulate (in specimen from South Africa, 32°43’S 26°35’E, anterior half of median surface unsculptured; in specimen from Tanzania, Mkomazi Game Reserve , mesoscutum granulate, with some rugosities near anterior margin; in specimen from South Africa, 28°40.90’S 28°55.78’E, mesoscutum granulate, except anterior fourth reticulate rugose). Notauli incomplete, reaching about 0.3 × length of mesoscutum (in specimen from Tanzania, Mkomazi Game Reserve , notauli reaching about 0.4 × length of mesoscutum; in specimen from Uganda, 0°33.836’N 30°21.700’E, notauli not distinct invisible among areolae present near anterior margin of mesoscutum). Mesoscutellum and metanotum shiny, unsculptured. Mesopleuron and metapleuron granulate, with irregular keels and areolae. Metapectal-propodeal disc with strong transverse posterior keel, reticulate rugose; propodeal declivity without longitudinal keels, completely reticulate rugose, with areolae less wide than those of metapectal-propodeal disc. In specimen from Madagascar, 12°30.52’S 49°10.53’E, propodeal declivity with two longitudinal keels and median area as rugose as lateral areas. Forewing hyaline, without dark transverse bands; distal part of 2r-rs& Rs vein much shorter than proximal part. Paramere ( Fig. 51C ) without distal inner pointed process, with proximal membranous process. Usually paramere about as long as penis, rarely (in specimens from South Africa, 32°21.260’’S 26°23.001’’E, and Madagascar, 21°15.05’S 47°24.43’E) much shorter than penis. Tibial spurs 1/1/2.
