Face strongly convex. Gena 0.37 times as high as eye width. Malar sulcus deep. Mandibles with blunt point. Antenna 2.8 times as long as head height, 13-segmented; antennomeres cylinrical, with no noticeable constrictions between them, thickening apically, ratio of antennomere lengths as following: 3.1:1.2:2.7:3.6:2.8:2.7:2.5:2.5:2.3:2.2:2.0:1.8:3.8. Pronotum with small humeral tubercles. Epomia uninterrupted. Lateral sides of pronotum with weak horizontal reticulation. Mesoscutum with well-developed notauli reaching its midlength. Horizontal groove across mesopleuron incomplete, reaching only 0.7–0.8 distance toward mesopleural suture. Mesopleuron with complete vertical perforated mesopleural suture running along posterior margin. Lateral sides of metapleuron with strong oblique reticulation (striation), with small smooth area divided by deep horizontal suture. Propodeum quadrate, convex, 0.5 times as long as thorax, dorsally with two lateral fields separated by noticeably reticulated ridge. Vertical section of radial vein 2 times as long as wide. Radial vein slightly arced, joining costal vein at 38º. Costal section of radial cell slightly (1.3 times) greater than width of pterostigma. Costal vein not developed beyond radial cell. Base of syntergite with numerous well-developed longitudinal wrinkles. Ovipositor sheath 6 times as long as wide, approximately 0.8 times as long as hind tibia, rounded apically, with small scattered setae.
