Mesosoma. Length of mesosoma 1.3 times as long as high; pronotal side smooth dorsally, coarsely crenulate medially and superficially granulate and with some rugae ventrally; precoxal sulcus only posteriorly absent and finely crenulate (Fig. 51); mesopleuron and metapleuron mainly smooth; mesoscutum smooth, except some punctulation; notauli narrow, shallow posteriorly and finely crenulate; scutellar sulcus 0.5 times as long as scutellum and with one long crenula (Fig. 52); scutellum smooth except some striae posteriorly; propodeum rugulose-granulate dorsally, except carinate median areola and some coarse rugae posteriorly (Fig. 52).

Metasoma. First tergite 1.7 times as long as apical width and slightly widened posteriorly (Fig. 54); first-second tergites with costate and somewhat oblique striation; third-fifth tergites with finer and more divergent striation and sixth tergite finely rugulose; medial length of second tergite 1.7 times than third segment; second suture coarsely crenulate; ovipositor sheath truncate apically and half as long as hind basitarsus; ovipositor stout (Fig. 56).
Colour. Pale yellow or ivory; antennal segments pale brown with faint yellowish transverse bands; stemmaticum, propleuron partly, mesopleuron antero-dorsally, antero-ventrally and below precoxal sulcus, mesoscutum laterally, scutellum and metanotum laterally, propodeum (except areola and posteriorly), inner and outer side of hind coxa, outer and inner side of hind femur mainly (except basally), metasomal tergites 1-5 basally and medio-posteriorly, tergite 6 nearly entirely dorsally (Fig. 54) and ovipositor sheath (except basally), dark brown; telotarsi and hypopygium baso-ventrally brown; wings mainly slightly infuscate; veins mainly (but of apical third of wing brownish yellow) and pterostigma medially dark brown; remainder of pterostigma and parastigma yellow.
Male
