Diagnosis.

Body small to medium-sized; terminal antennomere often rather acute apically (Fig. 6 o ); in lateral view scapus gradually narrowed basally, truncate apico-laterally, ventrally more or less as long as dorsally (Fig. 6 n ); eye setose, weakly emarginated (Fig. 6 j ); face coarsely rugose or punctate, often densely setose (Fig. 6 j ); clypeus without dorsal carina (Fig. 6 j ); malar suture often sculptured (Fig. 6 l ); labio-maxillary complex normal, not elongate (Fig. 6 l ); frons weakly concave behind antennal sockets, with some setae and a median groove (Fig. 6 k ); occiput normal (Fig. 6 k ), or sometimes with distinct lateral tubercles; mesosoma densely setose (Fig. 6 c ); middle lobe of mesoscutum nearly truncate anteriorly, not strongly produced in front of the lateral lobes (Fig. 6 d ); notauli moderately deep and complete, sometimes only shallow subposteriorly (Fig. 6 d ); precoxal suture absent; pleural suture smooth; scutellar sulcus moderately wide and crenulate (Fig. 6 d ); metanotum convex medially, and with a short median carina anteriorly (Fig. 6 e ); propodeum largely smooth and densely setose, without medio-longitudinal carina or groove (Fig. 6 e ); propodeal spiracle round, near middle of propodeum, and without tubercle above it (Fig. 6 c ); angle between veins 1 - SR and C + SC + R of fore wing about 60 °; vein SR 1 not reaching tip of fore wing (Fig. 6 a ); fore wing veins 1 - M and 1 - SR + M nearly straight (Fig. 6 a ); fore wing vein cu-a more or less interstitial (Fig. 6 a ); fore wing vein CU 1 b medium-sized, slender and reclivous (Fig. 6 a ); second submarginal cell of fore wing moderately short, and subparallel-sided (Fig. 6 a ); hind wing vein SC + R 1 distinctly longer than vein 1 r-m (Fig. 6 b ); membrane more or less evenly setose or largely glabrous near vein cu-a (Fig. 6 b ); lobes of tarsal claws usually large, with setae (Fig. 6 h ); metasoma robust; metasomal tergites (at least second and third) often largely and coarsely sculptured (Fig. 6 f ); first metasomal tergite largely coarsely sculptured except for the median area, which slightly convex and largely smooth, and without medio-longitudinal carina (Fig. 6 m ); lateral grooves of first metasomal tergite wide and crenulate; second metasomal tergite with a small rugose medio-basal area and connected to median carina posteriorly, lateral grooves crenulate (Fig. 6 f ); second metasomal suture deep and crenulate (Fig. 6 f ); third to fifth metasomal tergites with antero-lateral areas, and latero-posterior corner more or less protruding (Fig. 6 g ); female with posterior margin of fifth metasomal tergite broadly emarginate (Fig. 6 g ); hypopygium medium-sized and apically acute; upper valve of ovipositor without nodus subapically, and its lower valve without ventral teeth (Fig. 6 i ).
