Antenna with 44 segments, 1.6 times as long as fore wing; middle and subapical segments 3.3 and 2.7 times longer than wide, respectively; third antennal segment 1.4 times as long as fourth segment; width of face 0.8 times length of face and clypeus combined; clypeus flat in lateral view and ventral rim not differentiated from clypeus (Fig. 73); malar space 0.7 times as long as basal width of mandible; basal width of mandible 0.7 times as long as width of hypoclypeal depression; malar suture deep; distance between tentorial pits 2.9 times distance between pits and eyes (Fig. 72); length of eye in dorsal view 8.3 times as long as temple (Fig. 75); width of eye in lateral view 4.4 times as long as temple; ocelli large, POL:Od:OOL = 2:6:3; distance between front and hind ocelli as long as OOL (Fig. 72); face distinctly granulate submedially and orbita sparsely punctate, remainder of face superficially coriaceous; frons, vertex and temple smooth.

Mesosoma. Length of mesosoma 1.4 times as long as high; pronotal side smooth dorsally, moderately crenulate medially and granulate ventrally; precoxal sulcus only medially distinctly impressed and finely crenulate; mesopleuron mainly smooth; metapleuron superficially granulate (Fig. 73); mesoscutum smooth, except some punctulation; notauli narrow, shallow posteriorly and smooth; scutellar sulcus 0.5 times as long as scutellum and with one long crenula; scutellum smooth except some striae posteriorly; propodeum distinctly granulate dorsally, except carinate median areola, rugose medially and superficially granulate posteriorly (Figs 73, 74).

Wings. Fore wing: pterostigma 4.9 times as long as wide; r:2-SR:3-SR:SR1 = 5:9:15:26; vein r emerging before middle of pterostigma; vein cu-a slender (Fig. 71), 1-CU1:cu-a:2-CU1:3-CU1 = 3:8:34:7; posterior length of second submarginal cell 3.1 times its apical width. Hind wing: vein M+CU:1-M: 1r-m = 15:13:7; vein SR unsclerotised.

Hind coxa with satin sheen, superficially coriaceous and punctulate; length of hind femur:tibia:basitarsus:tarsus = 50:74:33:78; length of hind femur, tibia and basitarsus 6.0, 10.3 and 11.6 times as long as their width, respectively (Fig. 77); inner hind tibial spur 0.3 times as long as basitarsus.

Metasoma. First tergite 1.9 times as long as apical width and slightly widened posteriorly (Fig. 76); first-second tergites with rather coarse and somewhat oblique rugae; third-fifth tergites with more divergent rugulae and sixth tergite mainly coriaceous; medial length of second tergite 1.7 times longer than of third segment; second suture moderately crenulate; ovipositor sheath truncate apically and 0.6 times as long as hind basitarsus; ovipositor moderately stout (Fig. 78).

Colour. Pale yellow or ivory; antennal segments brown with yellowish transverse bands (Fig. 1); stemmaticum and face sublaterally pale brown; scapus, pedicellus, telotarsi, inner side of hind coxa, patch on outer side and inner side of hind femur, ovipositor sheath (except basally) and hypopygium baso-ventrally dark brown; propleuron partly, mesopleuron antero-dorsally, antero-ventrally and below precoxal sulcus, mesoscutum laterally, notaulic courses, scutellum and metanotum laterally, propodeum (except areola and posteriorly), outer side of hind coxa, metasomal tergites 1-3 basally and medio-posteriorly and tergites 4-6 nearly entirely dorsally (Figs 1, 76) blackish brown; wings largely slightly infuscate; veins mainly (but of apical third of wing brownish yellow) and pterostigma medially and subbasally dark brown; remainder of pterostigma and parastigma yellow.
