Dryinus yemenensis Olmi & van Harten 2006: 327 .

Description. ♀. Fully winged; body length 3.6–4.6 mm. Head black, except mandible, clypeus, anterior region of frons between antennal toruli and malar spacee testaceous-reddish; ventral side of head brown, except anterior half testaceous-reddish; antenna testaceous, except antennomeres 5–9 darkened and 10 whitish; prothorax testaceous- reddish; mesothorax, metathorax, metapectal-propodeal disc, propodeal declivity and petiole black; metasoma and legs testaceous-reddish, except stalks of meso- and metafemur and distal extremities of tibiae darkened. Specimen from Oman, 17°01.02’N 54°09.32’E, (length 3.7 mm) with slightly different colour (head black, except mandible, clypeus and part of malar space testaceous; antenna testaceous, except antennomeres 4–9 darkened; pronotum brown, except margins and posterior collar testaceous; legs testaceous, except meso- and metatibia and stalks of meso- and metafemur darkened). Antenna clavate; antennomeres in following proportions: 12:5:21:10:8:7:6:6:4:8. Head flat, dull, covered with many short setae, granulate, with frons sculptured by few irregular and longitudinal striae; frontal line complete; occipital carina complete; POL = 3; OL = 3; OOL = 7; OPL = 1; TL = 4. Pronotum shiny, unsculptured, humped, crossed by slight anterior transverse impression and strong posterior transverse furrow; anterior collar long; posterior collar very short; pronotal tubercle not reaching tegula. Mesoscutum dull, covered with short setae (so dense that sculpture hardly visible); mesoscutum granulate, with lateral regions and posterior surface reticulate rugose. Notauli almost complete and approximately reaching posterior margin of mesoscutum. Mesoscutellum and metanotum dull, granulate, covered with short setae. Metapectal-propodeal disc reticulate rugose, approximately as long as propodeal declivity; propodeal declivity with anterior half reticulate rugose and posterior half sculptured by transverse keels. Forewing with three dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (14:6). Protarsomeres in following proportions: 16:3:6:11:18. Enlarged claw ( Fig. 143B ) with one small subdistal tooth and one row of 4–5 very narrow lamellae similar to bristles. Protarsomere 5 ( Fig. 143B ) with three rows of 15 lamellae (one row composed of very long lamellae); apex with at least 18–25 lamellae. In specimen from Oman, 17°01.02’N 54°09.32’E, enlarged claw with one small subdistal tooth and seven very narrow lamellae similar to bristles + 1 seta; protarsomere 5 with two rows of 8 (slightly longer) + 10 lamellae and apex with at least 20 lamellae. Tibial spurs 1/1/2.

♂. Unknown (see remarks).
