Frons with strong reticulation, below eyes with weak reticulation and more shiny, clypeal area smooth; with a weak genal carina. Vertex outside ocellar triangle with strong reticulation, inside triangle with wrinkled sculpture. Mesoscutum with strong reticulation, meshes predominantly isodiametric but with elongate meshes in posterior one-third of midlobe; midlobe without median groove, with nine scattered adnotaular setae. Mesoscutellum with strong reticulation, median median part with weaker reticulation and more shiny than lateral parts, meshes elongate, submedian grooves ±distinct and diverging towards posterior part. Dorsellum with strong reticulation. Propodeum with median carina triangular, narrow anterior part very short; callus with three setae.
