Iin specimen from China, Guizhou Prov., Xiannudong, antenna brown, except segments 1–2 and 9–10 testaceous. In specimen from China, Nanling National Nature Reserve, clypeus testaceous. Antenna clavate; antennal segments in following proportions: 7:4.5:6:4.5:4:4:4:4:4.5:6.

Pronotum with anterior surface rugose and posterior surface smooth and shiny; posterior surface of pronotum longer than anterior surface and shorter than scutum (3:10); pronotal tubercle reaching tegula. Scutum shiny, smooth, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.4–0.6 length of scutum. Scutellum and metanotum shiny, smooth, unsculptured. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels and median area as rugose as lateral areas (in two specimens from China, Nanling National Nature Reserve, median area rugose, except central region smooth and shiny). Fore wing hyaline, without dark transverse bands; distal part of stigmal vein much shorter than proximal part (2:7). Protarsal segments in following proportions: 4.5:1.5:2:5:11. Enlarged claw (Plate 26D) with proximal prominence bearing one long bristle. Segment 5 of protarsus (Plate 26D) with basal part much shorter than distal part, with one–two rows of 9–22 large lamellae; distal apex with about two–eight large lamellae. Tibial spurs 1/1/2.

Mangshan, frontal line absent); POL = 4; OL = 2; OOL = 5; OPL = 3; TL = 4; greatest breadth of posterior ocelli about as long as OL; occipital carina complete. In specimen from China, Hunan, Mt. Mangshan, POL = 5; OL = 3; OOL = 7; OPL = 4; TL = 5; greatest breadth of posterior ocelli slightly longer than OL (3.5:3). Scutum shiny, punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 length of scutum. Scutellum and metanotum shiny, unsculptured. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two complete longitudinal keels and median area as rugose as lateral areas. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (2.5:8). Paramere (Plate 26C) with distal inner pointed process provided of inner distal margin slightly excavated. Tibial spurs 1/1/2.
