Dryinus inexpectatus Guglielmino & Olmi 2014b: 265 .

Description. ♀ ( Fig. 129C ). Fully winged; body length 9.8 mm. Head ferruginous, except vertex and almost entire frons brown; antenna with antennomeres 1–4 ferruginous (except distal extremity of antennomere 4 brown), antennomeres 5–7 brown (except distal half of antennomere 7 whitish) and 8–10 whitish; mesosoma ferruginous, except metanotum, metapectal-propodeal disc, propodeal disc, axillae, epicnemial sulcus, pleural sulcus and meso-metapleural suture black; petiole black; metasoma brown-ferruginous; legs ferruginous. Antenna clavate; antennomeres in following proportions: 18:9:67:44:35:25:19:17:14:17; ADOs present in antennomeres 5–10. Head ( Fig. 132F ) dull, granulate; occipital carina incomplete, present only behind and on sides of lateral ocelli, laterally not reaching eyes, not present on temple and on latero-ventral side of head; frontal line incomplete, not present near clypeus; clypeus bidentate; lateral ocelli not touching occipital carina; posterior margin of vertex straight ( Fig. 132F ); temple absent; POL = 5; OL = 4; OOL = 12; OPL = 3; greatest breadth of lateral ocelli longer than OPL (6:3). Pronotum ( Fig. 133A ) shiny, unsculptured, except some longitudinal keels on lateral regions; pronotum crossed by two deep transverse furrows; posterior collar long; pronotal tubercle not reaching tegula. Mesoscutum shiny, very weakly granulate (sculpture hardly visible). Notauli incomplete, reaching about 0.7 × length of mesoscutum. Mesoscutellum shiny, very weakly granulate (sculpture hardly visible). Metanotum shiny, unsculptured, with dense tuft of setae. Metapectal-propodeal disc reticulate rugose, much longer than propodeal declivity (55:30); propodeal declivity reticulate rugose, without longitudinal keels; median area of propodeal declivity dull, less rugose than rest of metapectal-propodeal disc + propodeal declivity. Mesopleuron and metapleuron shiny, very weakly granulate. Forewing with two large dark transverse bands; distal part of 2r-rs&Rs vein rectilinear, much longer than proximal part (35:19). Protarsomeres in following proportions: 31:4:13:40:65. Protarsomeres 2 and 3 produced into hook. Enlarged claw ( Fig. 133B ) with one large subapical tooth and one row of 15 lamellae. Protarsomere 5 ( Fig. 133B ) with two rows of about 20 + 21 lamellae; apex very long, with approximately 50 lamellae. Tibial spurs 1/1/2.
