Scutum, scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctures. Notauli complete, posteriorly separated; minimum distance between notauli shorter than greatest breadth of posterior ocelli. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface sculptured by two longitudinal median keels (region between above two keels sculptured by transverse keels) and with lateral areas rugose, sculptured by irregular keels; posterior surface with two longitudinal keels and median and lateral areas reticulate rugose. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein much longer than proximal part (36:8). Protarsal segments in following proportions: 18:3.5:8:35:46.
