13. Dryinus erenianus Olmi, Copeland & van Noort , sp. nov.

( Figs 127 , 128A )

Diagnosis. ♀ of Dryinus with head mostly black; frons sculptured by many irregular longitudinal striae; lateral ocelli not touching occipital carina; POL approximately twice as long as OL; temple absent; head (dorsally viewed) with lateral ocelli located in front of imaginary straight line joining posterior edges of eyes; mesosoma black; mesoscutum shiny, with lateral areas sculptured by many subparallel longitudinal keels, and median area medially punctate, unsculptured among punctures; forewing with distal part of 2r-rs&Rs vein less than 3 × as long as proximal part; metapectal-propodeal disc short, about as long as propodeal declivity; protarsomere 1 less than twice as long as 4; enlarged claw slightly shorter than protarsomere 5, with one big subapical tooth big ( Fig. 128A ).

Description. ♀ ( Figs 127A, B ). Fully winged; body length 6.0 mm. Head black, except mandible and ante- rior margin of clypeus testaceous-yellow; antenna brown, except scape, pedicel and flagellomeres 4–8 testaceouswhitish; mesosoma black; metasoma brown; proleg brown, except part of coxa and trochanter testaceous-whitish; meso- and metaleg brown, except distal extremity of coxae, trochanters, proximal extremity of tibiae, tarsomere 2 and distal half of tarsomere 1 testaceous-whitish. Antenna clavate; antennomeres in following proportions: 10:5:3 5:20:14:10:8:8:8:12. ADOs present in antennomeres 5–10. Head ( Fig. 127C ) weakly excavated, shiny, with frons sculptured by many irregular longitudinal striae, unsculptured among striae; occipital carina incomplete, only present behind ocellar triangle and on sides of lateral ocelli, laterally not reaching eyes, reaching about 0.7 × length of OOL; occiput little concave; temple absent; frontal line complete; POL = 4; OL = 2; OOL = 7; OPL = 1; greatest breadth of lateral ocelli longer than OPL (4:1). Pronotum shiny, crossed by two weak transverse impressions; anterior collar and disc punctate, unsculptured among punctures; lateral regions sculptured by many longitudinal striae, unsculptured among striae; posterior collar very short; pronotal tubercle not reaching tegula. Mesoscutum ( Fig. 127A ) shiny, with lateral areas sculptured by many subparallel longitudinal keels; median area medially punctate, unsculptured among punctures, laterally sculptured by longitudinal keels. Notauli incomplete, reaching about 0.8 × length of mesoscutum, hardly visible near posterior margin of mesoscutum. Mesoscutellum shiny, punctate, unsculptured among punctures. Metanotum shiny, with anterior half rugose and posterior half unsculptured. Metapectal-propodeal disc dull, reticulate rugose, about as long as propodeal declivity ( Fig. 127B ), without transverse posterior keel; propodeal declivity reticulate rugose, without longitudinal keels. Forewing ( Fig. 127D ) with two dark transverse bands; distal part of 2r-rs&Rs vein much longer than proximal part (20:12). Hind wing with distal third darkened. Protarsomeres in following proportions: 22:4:7:17:28. Enlarged claw ( Fig. 128A ) with one large subdistal tooth and one row of nine lamellae. Protarsomere 5 ( Fig. 128A ) with two rows of 19 lamellae; apex with about 12 lamellae. Tibial spurs 1/1/2.
