Antenna clavate; antennal segments in following proportions: 10:5:20:15:12:10:8:7.5:7:10.5. Head dull, reticulate rugose; face with wide, shiny, punctate and not rugose area in front of anterior ocellus and laterally almost reacheing inner margin of eyes; frontal line complete; occipital carina complete; POL = 4.5; OL = 2; OOL = 8; OPL = 7; TL = 11; greatest breadth of posterior ocelli longer than OL (3:2). Pronotum dull, reticulate rugose, short and transverse. Scutum with anterior half dull and reticulate rugose; posterior half punctate and unsculptured among punctures. Notauli complete, posteriorly separated; minimum distance between notauli longer than OL (10:2). Scutellum shiny, punctate and unsculptured among punctures. Metanotum dull, rugose. Propodeum dull, reticulate rugose, without transverse or longitudinal keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (6:9.5). Protarsal segments in following proportions: 22:4:4:13:19. Enlarged claw ( Plate 14C ) with one subapical tooth, without lamellae, bristles or hairs.

In specimen from China, Nanling National Nature Reserve, Protection Station, posterior half of scutum shiny and unsculptured, anterior half reticulate rugose. In specimen from China, Kuankuoshui, scutum with anterio third reticulate rugose, rest of surface punctate and unsculptured among punctures. Notauli complete, posteriorly separated; minimum distance between notauli longer than OL (13:3). Scutellum shiny, smooth, punctate, unsculptured among punctures. Metanotum dull, rugose. Propodeum dull, reticulate rugose, without transverse or longitudinal keels.
