Eyes densely setose. Transverse frontal ridge rounded dorsally and only indicated medially, about 1 ocellar diameter below median ocellus; scrobal depressions not present as sulci, uniting before reaching transverse ridge. Clypeus delimited by dorsal suture. Malar sulcus absent. Flagellum with 3 claval segments and 3 preclaval segments; 3rd flagellomere broader than long in females, similar to 2nd flagellomere; 3rd flagellomere longer than broad in males, longer than 2nd flagellomere. Mesosoma with raised-reticulate sculpture; pronotal collar not formed; mesoscutum with many short setae; notauli only indicated anteriorly; axillae advanced entirely anteriad of scuto-scutellar margin, dorsal surface about 2x longer than broad; scutellum with many unpaired dorsal setae, transverse, shorter than mesoscutum; prepectus not fused with mesopleuron. Postmarginal vein shorter than stigmal vein; stigma petiolate; submarginal vein with 3 or more setae. Propodeum extremely short; median carina meeting nuchal carina; paraspiracular groove present but not sharply defined.
