Diagnosis. Body yellowish; clavus and region between claval suture and radial vein brown; radial vein black; membrane of each hemelytron hyaline, brownish; scutellum with 1+1 paramedian brownish bands. Head wider than long, each mandibular plate shorter than or as long as clypeus. Prosternum sulcate; mesosternum carinate; and metasternum flat. Superior ridge of pygophore produced posteriorly, bisinuate; genital cup with superior process of dorsal rim flap-like; crown of parameres directed laterally, with dorsal and ventral processes forming a C-shape.

Description. Coloration. Yellowish; clavus and region between claval suture and radial vein brown; radial vein black; membrane of hemelytra hyaline, brownish; scutellum with 1+1 paramedian brownish bands ( Figs 3–5, 7–8 View FIGURES 1–8 , 24 View FIGURES 24–34 ).

Gonocoxites VIII (gc8) swollen, wider than long; mesial margins convex; each posterior margin straight; mesial and posterior margins setose, setae on posterior margins denser than on mesial margin ( Figs 35 View FIGURES 35–37 ). Mesial margins of gonocoxites VIII not juxtaposed, gonapophyses VIII (g9) visible, carinate medially ( Figs 6 View FIGURES 1–8 , 35–36 View FIGURES 35–37 ). Laterotergites VIII (la8) triangular; posterior margin smooth and straight; spiracle present. Gonocoxites IX (gc9) flat, twice as wide as long; posterior margin concave. Laterotergites IX (la9) depressed medially; rounded apically; not surpassing tergite VIII. Segment X rectangular, wider than long. Gonapophyses IX (g9) with 1+1 elliptical chitinellipsen (ch) ( Fig. 37 View FIGURES 35–37 ).
