Description. ♀ ( Figs 124A, BView FIGURE 124). Fully winged; body length 3.4–7.5 mm. Head ferruginous-testaceous; occasionally ventral side of head and central region of clypeus darkened; antenna brown, except antennomeres 9–10 yellow, distal part of antennomere 4 and proximal part of antennomere 5 whitish; propleuron and pronotum ferruginous-testaceous or brown-reddish; rest of mesosoma ferruginous, or brown-reddish, or completely black; occasionally mesosoma ferruginous, with metanotum and metapectal-propodeal disc and propodeal declivity black; petiole black; metasoma brown-reddish; legs brown-reddish. Head flat, granulate and slightly rugose or with irregular longitudinal keels; posterior margin of vertex convex; occipital carina complete, hardly visible on sides of occiput; OPL slightly shorter than OL; POL = OL. Pronotum ( Fig. 125DView FIGURE 125) dull, granulate, with slight keels around disc; pronotum crossed by strong posterior transverse furrow (anterior transverse impression absent); posterior collar long, longer than length of ocellar region; pronotal tubercle not reaching tegula. Mesoscutum dull, reticulate rugose, or sculptured by numerous irregular and longitudinal keels. Notauli slightly visible, incomplete, reaching approximately 0.5–0.7 × length of mesoscutum. Mesoscutellum dull, reticulate rugose. Metanotum dull, punctate, or rugose. Metapectal-propodeal disc ( Fig. 125EView FIGURE 125) reticulate rugose; propodeal declivity reticulate rugose, without longitudinal keels. Forewing with two dark transverse bands; distal part of 2r-rs&Rs vein curvilinear, much longer than proximal part. Protarsomere 1 longer than 4 (15:12); protarsomere 3 produced into hook. Enlarged claw ( Fig. 125FView FIGURE 125) with one large subdistal tooth and one row of 9–11 lamellae. Protarsomere 5 ( Fig. 125FView FIGURE 125) with two rows of about 17–37 lamellae; apex with at least 16 lamellae. Tibial spurs 1/1/1.

♂ (see remarks). Fully winged; body length 3.6–4.2 mm. Head black, except mandible, clypeus, malar space and palpi testaceous; antenna testaceous; mesosoma black; metasoma brown; legs testaceous, except meso- and metacoxa partly brown. Antenna filiform; antennomeres in following proportions: 8:7:21:14:15.5:15:13:12:10:12. Head dull, convex, completely reticulate rugose; frontal line complete; occipital carina incomplete, absent in temple; POL = 9; OL = 3.5; OOL = 4.5; OPL = 2; TL = 0; greatest breadth of lateral ocelli slightly longer than OL (4:3.5). Mesoscutum, mesoscutellum and metanotum dull, reticulate rugose. Notauli incomplete, reaching approximately 0.7 × length of mesoscutum. Metapectal-propodeal disc reticulate rugose, with strong irregular transverse posterior keel; propodeal declivity reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein slightly longer than proximal part (11:10); 2R1 cell open. Paramere with large dorsal process ( Fig. 125GView FIGURE 125). Tibial spurs 1/1/2.

Hosts. Unknown.

Distribution. Democratic Republic of the Congo, Gabon, Ivory Coast, Kenya, South Africa, Yemen.

Remarks. The ♂ above described was attributed doubtfully to Dryinus cariniceps Cameron, because a ♀ and a ♂ specimen of this species were both collected from the same locality (Yemen, Al-Kowd). However, in a further locality of Yemen (12 km NW of Manakhah) two ♀ specimens of Dryinus yemenensis Olmi & van Harten were collected by a Malaise trap together with 4 ♂ specimens similar to those collected in Al-Kowd. There is the pos- sibility that these ♂♂ are the opposite sex of Dryinus yemenensis. Only rearings of paired sexes, or DNA analysis will resolve this issue.
