Description. ♀. Apterous; body length 2.3 mm. Completely yellow-testaceous, except petiole black and eye grey. Antenna clavate; antennomeres in following proportions: 7:4:6:6:5:5:4:3.5:3.5:6. Head (Fig. 208D) excavated, shiny, unsculptured; frontal line complete; occipital carina absent; POL = 1; OL = 1; OOL = 5. Palpal formula 4/2. Pronotum shiny, unsculptured, crossed by transverse furrow. Mesoscutum less than twice as long as broad, without lateral pointed apophyses (Fig. 208E). Mesoscutellum shiny, smooth, sloping anteriorly. Metanotum excavated behind mesoscutellum (Fig. 208F). Metapectal-propodeal disc shiny, unsculptured, without track of median longitudinal furrow; propodeal declivity transversely striate. Mesopleuron shiny, unsculptured. Meso-metapleural suture distinct and complete. Protarsomeres in following proportions: 7:1.5:2.5:8:14. Enlarged claw (Fig. 211A) with one small subapical tooth, one peg-like seta and one bristle. Protarsomere 5 (Fig. 211A) with inner short proximal serrate region and one row of 14 lamellae; apex unusually very long (Fig. 211A), with four lamellae. Tibial spurs 1/0/1.

♂. Fully winged; body length 1.7–2.0 mm. Head black, except mandible testaceous; antenna brown; mesosoma black; metasoma brown–reddish; legs brown-testaceous. Antenna setose, filiform; antennomeres of specimen from South Africa, Uitkyk Pass, in following proportions: 5:4.5:5.5:5.5:4.5:5:4.5:5:4.5:6.5; antennomere 3 less than 3 × as long as broad: 5.5:2 (in ♂ specimen from South Africa, Uitkyk Pass). Head shiny, setose, strongly punctate, unsculptured among punctures; frontal line of holotype incomplete, short, visible only in front of anterior ocellus; frontal line of ♂ specimen from South Africa, Uitkyk Pass, absent; occipital carina absent; in ♂ specimen from South Africa, Uitkyk Pass, POL = 4; OL = 1.3; OOL = 4.5; greatest breadth of lateral ocelli lobger than OL (2:1.3). Vertex of head with two oval smooth and shiny areas situated between lateral ocelli and eyes (areas surrounded anteriorly by very high carina (Fig. 208G) and posteriorly by lower carina continuing on temple and behind ocellar triangle (Fig. 208G)). Temple distinct, crossed by sharp carina parallel to posterior margin of eyes. Palpal formula 4/2. Mesoscutum shiny, strongly punctate. Notauli complete, posteriorly separated; minimum distance between notauli as long as (in holotype) or shorter (1.3:2; in specimen from South Africa, Uitkyk Pass) than greatest breadth of lateral ocelli. Mesoscutellum and metanotum shiny, slightly punctate, unsculptured among punctures. Metapectal-propodeal disc dull, slightly reticulate rugose, with median longitudinal furrow; areolae of metapectal-propodeal disc small; propodeal declivity without longitudinal or transverse keels. Forewing hyaline, without dark transverse bands; with only costal cell surrounded by strongly pigmented veins; other basal cells surrounded by less pigmented veins); 2R1 cell open; 2r-rs& Rs vein regularly curved, with distal part longer than proximal part (approximately 11:4). Dorsal process of paramere (Fig. 219D) short and slender, with apex pointed. Tibial spurs 1/1/2 .
