Male
.
Macropterous; length
1.9–3.1 mm
. Head black, except clypeus brown and mandible partly brown and testaceous; head occasionally brown; antenna brown; mesosoma black, occasionally brown; metasoma brown; legs brown, except articulations, stalks of femora and part of tibiae and tarsi testaceous. Antenna filiform, hairy; antennal segments in the following proportions: 8:5:9:9:9:9:8:8:7:9. Head convex, shiny, finely punctate, unsculptured among punctae; frontal line absent; occipital carina complete; POL =7; OL= 3; OOL=5.5; OPL= 3; TL= 5. Occasionally head punctate and slightly granulated. Scutum, scutellum and metanotum shiny, quite finely punctate, unsculptured among punctae. Occasionally scutum slightly rugose near posterior margin. Notauli incomplete, reaching approximately 0.6× length of scutum. Propodeum reticulate rugose, without longitudinal or transverse keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (2:

Biology: In the only parasitized host collected in Kogelberg Nature Reserve (
South Africa
), the larval thylacium was situated in the dorsal side between the head and pronotum. This position is typical of
Deinodryinus
species.
