(Figs 81B, 82, 83A)

Diagnosis. Macropterous ♀ of Deinodryinus with head strongly punctate, unsculptured among punctures; frons without frontal line and lateral keels joining lateral ocelli to antennal toruli; mesosoma without strong constriction between prothorax and mesothorax (Fig. 81B); posterior surface of pronotum with sharp lateral margins; protarsomere 1 much shorter than 4; distal region of protarsomere 5 very slender (Fig. 83A).

Description. ♀ (Figs 81B, 82). Fully winged; body length 3.4 mm. Head ferruginous; antenna testaceous, except antennomere 10 brown; mesosoma ferruginous, except lateral regions of pronotum brown, metanotum and metapectal-propodeal disc black; petiole black; metasoma testaceous, except anerior half of first sclerite brown; legs testaceous, except brown spot on outer side of metacoxa. Antenna clavate; antennomeres in following proportions: 9:5:16:10:7:7:6:6:6:8. Head (Fig. 82C) slightly swollen, shiny, strongly punctate, unsculptured among punctures; frontal line absent; frons without lateral keels; vertex behind ocellar triangle without two oblique keels connecting lateral ocelli to occipital carina; occipital carina complete; POL = 5; OL = 4; OOL = 8; OPL = 7; TL = 6; greatest breadth of lateral ocelli shorter than OL (3:4). Pronotum anteriorly crossed by strong transverse impression, shiny, smooth, punctate, unsculptured among punctures; posterior surface of pronotum slightly broader than long (21:16), slightly shorter than mesoscutum (16:18), with lateral margins sharp; pronotal tubercle reaching tegula. Mesoscutum and mesoscutellum shiny, punctate, unsculptured among punctures. Notauli (Fig. 82A) incomplete, reaching approximately 0.7 × length of mesoscutum. Metanotum rugose. Metapectal-propodeal disc reticulate rugose, with- out transverse posterior keel; propodeal declivity reticulate rugose, except posterior third sculptured by transverse keels. Forewing (Fig. 82D) with two dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (15:8). Protarsomeres in following proportions: 10:3:6:18:28. Enlarged claw (Fig. 83A) with one lamella situated further distally than proximal prominence. Protarsomere 5 (Fig. 83A) with two rows of 26 (short) + 8 (long) lamel- lae; apex very slender, with 3 lamellae, one of which very long. Tibial spurs 1/1/2.
