DIAGNOSIS: Pronotum, scutellum and hemelytra with dark puncture; membrane with distinct dark markings (Figure 1B); lateral margin of genital capsule rounded, apex relatively thick with densely long setae in dorsal view (Figure 2B); median process of genital capsule short, not reaching to dorsal wall of capsule in lateral view (Figure 2H), process rectanglar and broader apically (Figure 3B); paramere curved subapically, its apex bifurcated (Figure 4B).

DESCRIPTION: Male: Body oval and elongated, length 12.30–13.26. COLOR. mostly greenish. Head: generally greenish, sometimes reddish; antennae almost brown, first segment with dark line laterally, third segment dark brown, 1/2 apical part of fourth and fifth segment dark brown; rostrum green, apex of fourth rostral segment dark brown. Thorax: pronotum entirely green except for pale anterolateral margin, with densely dark punctures, anterior part of pronotum with dark line laterally; scutellum entirely greenish, with dark punctures; hemelytra mostly greenish with entirely dark punctures; membrane transparent tinged with brownish, with dark V-shaped markings; legs almost green, sometimes reddish; base of tibia with dark band, apical part brown; third tarsal segment brown. Abdomen: entirely green. SURFACE AND VESTITURE: Body slightly glossy, with distinct dark punctures, covered with silvery short pubescences; antenna with densely short pubescences; legs with setae. STRUCTURE. Head: width of head longer than length, mandibular plate projected as long as clypeus dorsally; length of antennae longer than length of body, first segment longer than 2 times length of head; rostrum not reaching to midcoxae. Thorax: anterior and posterior margin of pronotum rounded; mesal length of scutellum longer than width; lateral margin of hemelytra rounded; legs generally long; femur distinctly thick; first tarsal segment as long as third segment. Abdomen: margin rounded, not reaching to apex of membrane. GENITALIA: lateral margin of genital capsule rounded, apex relatively thick with densely long setae in dorsal view (Figure 2B); process of genital capsule short, not reaching to height of capsule in lateral view (Figure 2H), process rectangular and broader apically (Figure 3B); paramere curved subapically, its apex bifurcated (Figure 4B).

Female: Body oval and elongated, length 13.28–13.34. COLOR: as in male. SURFACE AND VESTITURE: as in male. STRUCTURE: as in male except for genital segment. GENITALIA: lateral seventh abdominal segment flat, central seventh abdominal segment concave and convex at center; gonocoxites 8 large and divergent, extending the same length with laterotergites 9; laterotergites 8 small and compact, shorter than gonocoxite 8 and laterotergite 9; laterotergites 9 slightly visible, touching at base but divergent at apex (Figure 5B); spermatheca curved and robust, sclerotized area short (Figure 5G).
