7 black; gonoplac black.

Antenna with solid clava. Face below level of toruli with weak reticulation, clypeus smooth, frons with strong reticulation, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, ±elongate on midlobe; midlobe without a median groove, with ten scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate, without median groove; submedian grooves weak but traceable, running close to and parallel with lateral margins of mesoscutellum; anterior pair of setae situated just behind middle of mesoscutellum.
