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 ).

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.
