Diagnosis. Antenna situated between eyes and not on a protuberance ( Fig. 2 View Figure ), scapus short and cylindrical, slightly longer than third flagellomere, not reaching top level of vertex in lateral view ( Fig. 2 View Figure ), flagellar segments with long setae apically, third flagellomere (including annellus) longer than fourth flagellomere, and apical flagellomere without apical spine ( Fig. 10 View Figure ); eyes large, converging dorsally and strongly protruding anteriorly in respect to anterior level of frons, with remotely placed and rather long setae ( Figs 11–13 View Figure ); face 2.5 x higher than its minimum width and narrowed dorsally ( Fig. 11 View Figure ); clypeus distinctly convex, nearly twice as wide as high and strongly narrowed dorsally, and anterior tentorial pits large ( Figs 2 View Figure , 11 View Figure ); frons strongly narrowed anteriorly, without distinct carinae and concave ( Fig. 12 View Figure ); maxillary and labial palpi with 4 and 2 segments, respectively ( Figs 2 View Figure , 13 View Figure ); occipital carina present laterally and medio-dorsally absent ( Figs 1, 2 View Figure ); mandible wide basally and narrow apically, sickle-shaped, with 2 teeth but second tooth minute ( Fig. 13 View Figure ); malar suture distinct and narrow ( Fig. 11 View Figure ); head about 1.5 x wider than mesosoma; notauli complete and wide; mesoscutum twice wider than long and largely smooth ( Fig. 7 View Figure ); precoxal sulcus distinct and coarsely crenulate; mesosternum of ♀♀ largely glabrous and convex ( Fig. 6 View Figure ); propodeum medio-posteriorly with normal ventral petiolar condylus, near level of bases of hind coxae and without V-shaped carina; postpectal carina absent; scutellum without distinct depression medio-posteriorly ( Fig. 3 View Figure ); propodeum areolate and postero-medially depressed ( Fig. 3 View Figure ); marginal cell of fore wing long and closed ( Fig. 4 View Figure ); vein M+CU1 of fore wing largely unsclerotized (except distally; Fig. 4 View Figure ); veins r-m and 1-SR+M of fore wing absent; vein 2-1A of fore wing unsclerotized; marginal cell of hind wing strongly narrowed apically; vein 1r-m of hind wing 0.2 x vein 2-SC+R and 1.3 x vein 1-M ( Fig. 5 View Figure ); vein cu-a of hind wing reduced, unsclerotized (except basally; Figs 4, 5 View Figure ); vein 1-1A of hind wing absent distally; vein 1-SC+R of hind wing completely sclerotized; hind femur approx. 6 x longer than wide; middle and hind tibiae and tarsi very long and slender ( Figs 1 View Figure , 9 View Figure ); tarsi (including telotarsi) simple and slender, weakly and evenly curved, ventrally mainly glabrous ( Fig. 15 View Figure ); first tergite petiolate, its apical half widened, slightly narrowed near apex and flattened, about 5 x as long as its maximum width, and 0.3 x length of metasoma ( Fig. 1 View Figure ); spiracles of first tergite situated behind middle of tergite ( Fig. 8 View Figure ) and dorsope and laterope absent, segment ventrally angulate, its sternite strongly sclerotized but separated from tergite ( Fig. 16 View Figure ); metasoma of ♀ strongly compressed from middle of third tergite onwards, 0.7 x width of propodeum or less ( Fig. 8 View Figure ); fifth sternite truncate apically; hypopygium of female with medium-sized setae apically ( Fig. 14 View Figure ); ovipositor laterally compressed, its basal half widened in lateral view ( Fig. 14 View Figure ) and rounded dorsally, widened in lateral view ( Fig. 14 View Figure ), in exserted position about 1.2 x as long as hind basitarsus and straight; ovipositor sheath slender, about 4 x as long as wide, shorter than apical height of metasoma and about 0.2 x length of first tergite ( Fig. 1 View Figure ).
