Redescriptions:

Female.

Micropterous, with forewing much reduced, reaching transverse furrow behind scutellum. Length 2.5–2.9 mm. Completely yellow­testaceous, except antennal segments 6–10 or 7–10, petiole and distal half of metasoma brown­dark.Antenna clavate; antennal segments in the following proportions: 7:4:18:8:8:8:7:7:6:8. Head shiny, smooth, punctate, unsculptured among punctae; occipital carina complete; frontal line absent; POL =3; OL = 2; OOL=8; OPL=5; TL =9. Pronotum shiny, smooth, finely punctate, unsculptured among punctae, not crossed by transverse impressions, with short anterior collar; pronotal tubercle reaching tegula. Scutum much reduced, unsculptured. Notauli present, posteriorly joint. Scutellum and metanotum shiny, smooth, unsculptured. Metathorax + propodeum dull, reticulate rugose. Enlarged claw ( Fig. 21 ) with one peg­like lamella situated further distally than proximal prominence. Segment 5 of protarsus ( Fig. 21 ) with two rows of about 18–28 lamellae; distal apex with about 3–5 lamellae, among which one markedly long. Tibial spurs 1/1/2.

Male.

Macropterous; length 1.9–2.2 mm. Head black; mandible testaceous; antenna brown; mesosoma and metasoma black; legs brown, except tarsi and protibia testaceous. Antenna filiform, with hairs shorter than breadth of segments; antennal segments in the following proportions: 6:4:7:7:7:7:6:6:6:7. Head shiny, smooth, punctate, unsculptured among punctae; frontal line absent; face with longitudinal median furrow; occipital carina complete. Head of holotype with POL =4; OL= 2.5; OOL= 6; OPL= 5; TL =5.5; in specimen from Senegal, 15 km S Guignol, POL= OPL; in specimen from Namibia, 23°34'S 15°03'E, POL = 5; OL = 2.5; OOL = 5. Scutum shiny, smooth, punctate, unsculptured among punctae. Notauli incomplete, reaching approximately 0.3–0.5× length of scutum. Scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctae. Propodeum completely reticulate rugose, without longitudinal or transverse keels, with posterior surface sculptured by areolae smaller than those of dorsal surface. Forewing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (3:7). Paramere ( Fig. 22 ) about as long as penis, with inner narrow proximal branch wrapping penis. Tibial spurs 1/1/2.
