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

( Figs 121E , 122 , 123D )

Diagnosis. ♀ of Dryinus with head testaceous-ferruginous, except ocellar triangle brown ( Fig. 123D ); 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. 121E ) slightly shorter than protarsomere 5 and with one big subapical tooth.

Description. ♀ ( Figs 122 , 123D ). 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. 122C ) 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. 122B ); 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. 122A ) 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. 122D ) 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. 121E ) with one large subdistal tooth and one row of 16 lamellae. Protarsomere 5 ( Fig. 121E ) with two rows of 51 lamellae; apex with approximately 24 lamellae. Tibial spurs 1/1/2.
