Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part; with a sulcus from eye to lateral ocellus and from there to median ocellus.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe, parts close to notauli ±rugose; midlobe with a weak median groove in posterior one-third, with 15 adnotaular setae in two rows on rugose parts. Mesoscutellum with weak reticulation on median part and strong reticulation on lateral parts, meshes elongate; submedian grooves distinct, slightly curved and diverging towards posterior part; with a strong and complete median groove; with six setae scattered over lateral parts. Dorsellum with strong reticulation, without median carina. Propodeum with a strong median carina that expands in posterior part; median part with strong irregular carinae, lateral parts with strong reticulation; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with four longitudinal carinae; tergites with strong reticulation.
