4. Dryinus bellicosus Olmi, Copeland & van Noort  , sp. nov.

( Figs 121EView FIGURE 121, 122View FIGURE 122, 123View FIGURE 123 DView FIGURE 123)

Diagnosis. ♀ of Dryinus  with head testaceous-ferruginous, except ocellar triangle brown ( Fig. 123View FIGURE 123 DView FIGURE 123); mesosoma totally testaceous-ferruginous; head (dorsally viewed) with lateral ocelli located in front of imaginary straight line joining posterior edges of eyes; notauli almost complete, posteriorly separated; protarsomere 1 less than twice as long as 4; enlarged claw ( Fig. 121EView FIGURE 121) slightly shorter than protarsomere 5 and with one big subapical tooth.

Description. ♀ ( Figs 122View FIGURE 122, 123DView FIGURE 123). Fully winged; body length 6.6 mm. Head testaceous-ferruginous, except ocellar triangle brown; antenna testaceous, except antennomere 6, distal half of antennomere 5 and proximal half of antennomere 7 black; mesosoma testaceous-ferruginous; petiole black; metasoma testaceous ferruginous; legs testaceous. Antenna clavate; antennomeres in following proportions: 13:7:56:32:25:16:11:11:10:12. ADOs present on antennomeres 5–10. Head ( Fig. 122CView FIGURE 122) dull, granulate and slightly irregularly striate; frontal line complete; occipital carina complete; POL = 3; OL = 3; OOL = 12; OPL = 2; TL = 2; greatest breadth of lateral ocelli longer than OPL (3.5:2). Head (dorsally viewed) with lateral ocelli located in front of imaginary straight line joining posterior edges of eyes. Pronotum shiny, unsculptured, crossed by slight anterior transverse impression and strong posterior transverse furrow ( Fig. 122BView FIGURE 122); anterior collar slightly visible; posterior collar long, with two long lateral longitudinal keels (reaching sides of disc) and few short medial longitudinal keels; pronotal tubercle not reaching tegula. Mesoscutum ( Fig. 122AView FIGURE 122) shiny, punctate and very slightly irregularly striate, with surface close to posterior margin reticulate rugose. Notauli almost complete, hardly visible among areolae located near posterior margin of mesoscutum. Notauli posteriorly separated. Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc reticulate rugose, about twice as long as propodeal declivity; propodeal declivity reticulate rugose, without longitudinal keels. Forewing ( Fig. 122DView FIGURE 122) with two brown transverse bands; distal part of 2r-rs&Rs vein much longer than proximal part (27:13). Protarsomeres in following proportions: 32:4:9:26:41. Protarsomere 3 produced into hook. Enlarged claw ( Fig. 121EView FIGURE 121) with one large subdistal tooth and one row of 16 lamellae. Protarsomere 5 ( Fig. 121EView FIGURE 121) with two rows of 51 lamellae; apex with approximately 24 lamellae. Tibial spurs 1/1/2.
