19. Deinodryinus piceus Olmi, Copeland & van Noort , sp. nov.

( Figs 92D , 93 , 94A )

Diagnosis. Macropterous ♀ of Deinodryinus with head strongly punctate, unsculptured among punctures ( Fig. 94A ); frontal line absent; frons without lateral keels joining lateral ocelli to antennal toruli; posterior surface of pro- notum with sharp lateral margins; mesosoma without strong constriction between prothorax and mesothorax ( Fig. 94A ); protarsomere 1 slightly shorter than 4; distal region of protarsomere 5 robust ( Fig. 92D ).

Description. ♀ ( Figs 93 , 94A ). Fully winged; body length 3.4–3.5 mm. Head brown, except mandible, clypeus and anterior half of frons ferruginous; antenna testaceous, except antennomeres 7–10 brown; mesosoma brownblack, except lateral and posterior margins of pronotum and pronotal tubercle ferruginous; posterior half of median region of mesoscutum yellow, with margins ferruginous; metasoma and legs brown. Antenna clavate; antennomeres in following proportions: 7:4:12:5:4:4:5:5:5:6.5. Head ( Fig. 93C ) slightly swollen, shiny, strongly punctate, unsculptured among punctures; frontal line absent; frons without lateral keels near orbits directed towards antennal toruli; vertex behind ocellar triangle without two oblique keels connecting lateral ocelli to occipital carina; occipital carina complete; POL = 4; OL = 2; OOL = 6.5; OPL = 5; TL = 7; greatest breadth of lateral ocelli longer than OL (3:2). Pronotum anteriorly crossed by strong transverse impression, shiny, finely punctate, unsculptured among punctures; posterior surface of pronotum approximately as long as broad, as long as mesoscutum, with lateral margins sharp; pronotal tubercle reaching tegula. Mesoscutum and mesoscutellum shiny, punctate, unsculptured among punctures ( Fig. 93A ). Notauli incomplete, reaching approximately 0.5 × length of mesoscutum. Metanotum shiny, unsculptured. Metapectal-propodeal disc reticulate rugose, without transverse posterior keel; propodeal declivity reticulate rugose, except posterior half sculptured by transverse keels. Forewing ( Fig. 93D ) with two dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (9:7). Protarsomeres in following proportions: 7:2:5:10:21. Enlarged claw ( Fig. 92D ) with one bristle situated further distally than proximal prominence. Protarsomere 5 ( Fig. 92D ) with three rows of approximately 50 lamellae (many lamellae longer than others); apex with at least 20 lamellae. Tibial spurs 1/1/2.

♂. Unknown.
