Redescription:

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: 7 in holotype; 3.5: 8 in paratype); pterostigma less than four times as long as broad; veins surrounding BC and SBC cells generally as pigmented as veins surrounding CC cell, occasionally less pigmented. Paramere ( Fig. 4 ) about as long as penis, with inner broad proximal branch wrapping penis. Tibial spurs 1/1/2.

Female. Unknown.

Other material examined: SOUTH AFRICA: Western Cape: Kogelberg Nature Reserve, parasitized host collected 17.i.2003, dryinid larva pupated 30.i.2003, dryinid adult emergence 16.ii.2003, reared from an adult of Colistra parvulus (Linnavuori) feeding on Berzelia lanuginosa (Bruniaceae) , M. Olmi reared, (OLM); 5♂ Walker Bay Nature Reserve, 34°27.41'S 19°21.39'E, 4.x–1.xi.1997, 29.xi–26.xii.1997, 8.iv–16.v.1998, yellow pan trap, S. van Noort & B. Fisher (SAMC); 21♂ same locality, 11.viii–6.ix.1997, S. van Noort, (20 SAMC, 1 OLM); 2♂ same locality, 17–31.v.1997, Malaise trap, S. van Noort (SAMC).

Distribution: South Africa.

Hosts: Cicadellidae ( Guglielmino & Olmi 2006) , South Africa (Kogelberg Nature Reserve): Colistra parvulus (Linnavuori) (M. Stiller det.).

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.
