Qingliangfeng, clypeus brown-reddish); antenna brown, except segment 1 testaceous (in specimen from China, Mt. Qingliangfeng, antennal segments 2–10 brown, except ventral side testaceous); mesosoma and metasoma black; legs totally testaceous, or with club of metafemur, metatibia and metatarsus brown. Antenna filiform; antennal segments in following proportions: 4:2:2:3:3:3:3:3:3:4.2. Head shiny, finely punctate, unsculptured among punctures; vertex with two oblique keels connecting posterior ocelli to occipital carina (in further specimen collected in type locality (Mt. Fanjingshan) above oblique keels absent); frontal line absent; POL = 2; OL = 1; OOL = 3; OPL = 1; TL = 1.5; greatest breadth of posterior ocelli as long as OPL; occipital carina complete. Scutum shiny, with anterior fourth punctate and unsculptured among punctures; rest of surface unsculptured. Notauli incomplete, reaching about 0.50–0.65 length of scutum. Scutellum and metanotum smooth. Propodeum reticulate rugose, with strong transverse keel between dorsal and posterior surface; posterior surface reticulate rugose, with two longitudinal keels, lateral areas reticulate rugose and median area smooth. In further specimen collected in type locality (Mt. Fanjingshan) median area of posterior surface of propodeum partly smooth and partly rugose. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (2:5). Paramere (Plate 21D) with distal inner pointed process. Tibial spurs 1/1/2.
