Description. ♀. Fully winged; body length 4.6–5.1 mm. Head black, except mandible, clypeus and some× malar space and narrow stripe between antennal toruli and between eyes and antennal toruli testaceous; antenna totally testaceous, or brown, except scape and pedicel testaceous, or testaceous, except flagellomeres 1–2 slightly darkened; mesosoma black (occasionally pronotum with lateral margins, posterior collar and pronotal tubercle testaceous); metasoma brown or brown–testaceous; legs testaceous, except coxae, clubs of femora and protrochanter partly brown (occasionally legs brown, except coxae, trochanters, clubs of femora and tibiae partly testaceous; last tarsomere of meso- and metalegs brown); in specimen from South Africa, 33°30.747’S 25°24.644’E, legs testaceous, except metacoxa brown. Antenna clavate; antennomeres of holotype of D. ugandanus in following proportions: 13:6:28:14:10:9:6:6:6:8; antennomeres of holotype of D. constantiae in following proportions: 13:5:32:21:16:12:9:8:6:9. ADOs present on antennomeres 5–10. Head dull, slightly convex or flat, granulate and completely reticulate rugose (with region of vertex along occipital carina sculptured by numerous short longitudinal keels); frontal line complete; occipital carina complete; holotype of D. ugandanus with POL = 4; OL = 2; OOL = 9; OPL = 3; TL = 4; holotype of D. constantiae with POL = 3.5; OL = 3; OOL = 9; OPL = 3; TL = 6. Pronotum dull, granulate (occasionally partly unsculptured or punctate), with slight irregular striae, crossed by transverse furrow; disc slightly humped; posterior collar very short or absent; pronotal tubercle not reaching tegula. Mesoscutum dull, granulate and reticulate rugose. In holotype of D. constantiae, mesoscutum with median region almost completely granulate, not reticulate rugose. Notauli absent in holotype of D. ugandanus (in holotype of D. constantiae, notauli incomplete, reaching about 0.5 × length of mesoscutum; in specimen from South Africa, 32°26.387’S 20°34.501’E, notauli almost reaching posterior margin of mesoscutum). Mesoscutellum granulate and reticulate rugose (in holotype of D. constantiae, mesoscutellum granulate, not rugose). Metanotum granulate and rugose. Metapectal-propodeal disc reticulate rugose, approximately as long as propodeal declivity; propodeal declivity reticulate rugose, with two short incomplete longitudinal keels. Forewing with 1–2 transverse bands very slightly darkened (in specimen from South Africa, 33°30.747’S 25°24.644’E, forewing hyaline, without dark transverse bands or spots; in specimen from South Africa, 32°26.387’S 20°34.501’E, forewing hyaline, with very small dark spot around 2r-rs&Rs vein); distal part of 2r-rs&Rs vein longer than proximal part (15: 9 in holotype of D. ugandanus; 13: 9 in holotype of D. constantiae). Protarsomeres of holotype of D. ugandanus in following proportions: 26:4:7:11:20. Protarsomeres of holotype of D. constantiae in following proportions: 33:3:6:12:20. Enlarged claw (Figs 144B, C) with one large subdistal tooth and one row of 5–8 lamellae. Protarsomere 5 (Figs 144B, C) with one row of 8–13 lamellae; apex with about 9–13 lamellae. Tibial spurs 1/1/2.

Hosts. Unknown.
Distribution. Sierra Leone, South Africa, Uganda.
Remarks. Dryinus ugandanus is here considered as a senior synonym of D. constantiae, because a study of ♀♀ attributed to D. constantiae showed a variability concerning the notauli. Some specimens have the notauli almost or totally invisible, as in D. ugandanus, so that they can be identified as D. ugandanus and attributed to group 2. For this reason, D. ugandanus can be attributed to both groups, 1 and 2. The conspecificity of these two species is highly likely.
