Head. Antenna with 28 segments remaining; third antennal segment 1.1 times fourth one (10:9); middle segments 2.3 times its width (7:3); width of face 0.9 times length of face and clypeus combined (19:21); malar space as long as mandible width; mandible width 0.6 times as long as hypoclypeal depression (6:10); malar suture present; distance between tentorial pits 5.0 times distance between pits and eyes (10:2; Fig. 22); in dorsal view height of eye 5.8 times as long as temple (23:4); in lateral view width of eye 3.2 times as long as temple (19:6); ocelli in high triangle, POL:Od:OOL = 3:6:4; distance between front and hind ocelli:OOL = 3:4 (Fig. 24); face rugose; frons, vertex and temple smooth.

Mesosoma. Length of mesosoma 1.5 times as long as high (90:60); pronotal side smooth dorsally, crenulate anteriorly, finely granulate ventrally; precoxal sulcus long, deep and crenulate (Fig. 23); mesopleuron smooth; mesoscutum smooth; notauli deep and crenulate; propodeum mainly rugose and without distinct medial areola.

Wings. Fore wing: pterostigma 4.8 times as long as wide; r:2-SR:3-SR:SR1=10:18:28:50; vein r arising submedially from pterostigma (Fig. 28); vein 1-CU1 quadrate; vein cu-a perpendicular; posterior length of second submarginal cell 3.2 times its width (38:12). Hind wing: vein M+CU as long as vein 1-M and 3.5 times vein 1r-m = 35:10 (Fig. 26).

Legs. Hind coxa smooth; length of hind femur:tibia:basitarsus:tarsus = 71:92:13:43; length of hind femur, tibia and basitarsus 5.9, 10.2 and 10.75 times their width, respectively.

Metasoma. First-second tergites with median carinae and parallel striae; first tergite 1.2 times as long as its apical width (Fig. 3); medial length of second tergite 1.6 times third (42:27); third-fifth tergites basally with divergent striation, granulate medio-apically; sixth tergite mainly granulate; ovipositor sheath pointed apically (0.5 mm), 0.4 times as long as hind basitarsus (20:46); ovipositor slender, nearly straight, enlarged basally (Fig. 25).

Colour. Yellow; antenna yellowish, but darkened basally; palpi pale yellow; stemmaticum black; pronotum dorsally, notauli and mesonotum laterally, side of scutellum and axilla, propodeum medially blackish-brown or black; first-sixth tergites black medially, pale yellow laterally; wings subhyaline.

Male.

Unknown

Variation.

Antenna with 45(1) and 49(1) segments and 1.4 times as long as body; first tergite 1.1-1.3 times as long as apical width; medial length of metasomal second tergite 1.7-1.8 times as long as third tergite medially; body length 5.2-5.9 mm; fore wing length 4.3-4.5 mm.

Etymology.

From ‘curvus’ (Latin for bend), because of the curved vein SR of hind wing.
