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.
