Diagnosis. Yellow longitudinal stripe dorsally, basally on pronotum and medially along entire scutellum. Head longer than wide, mandibular plates longer than clypeus. Antenniferous tubercles with lateral and ventral tubercles. Antennomere II longer than the remaining antennomeres taken together. Genital cup of pygophore striate. Paramere crown falcate, with microtrichia laterally. Segment X up to two times longer than wide. Gonocoxites VIII as long as wide, swollen, facing posteriorly; posterior and mesial margins setose.

Redescription. Coloration. Dark green, with a median yellow stripe anteriorly on pronotum and along scutellum; corium of each hemelytron yellow with several dark green punctations; membrane of each hemelytron hyaline with dark, irregularly shaped markings ( Figs 1-2 View FIGURES 1–8 , 9 View FIGURES 9–20 ). Ventrally, body and legs greenish-yellow, with dark green punctations; yellow median stripe from sternites IV to VII ( Fig. 10 View FIGURES 9–20 ). Antennae brownish, labium dark brown.

Head. Longer than wide; lateral margins of head sinuous; mandibular plates longer than clypeus, each rounded apically, inner margins ahead of clypeus contiguous; antenniferous tubercles visible in dorsal view ( Fig. 9 View FIGURES 9–20 ). Each antenniferous tubercle with lateral and ventral processes ( Fig. 12 View FIGURES 9–20 ). Each antennomere I not reaching head apically; each antennomere II longer than the remaining antennomeres together; each antennomere IV wider in the basal half than in the apical half, basal half glabrous, apical half setose ( Fig. 11 View FIGURES 9–20 ); each antennomere V entirely setose; proportion of antennomeres II>IV>V>I>III. Proportion of labiomeres II>III>I=IV.

Thorax. Pronotum about two times and a half wider than long; each anterior margin concave; each anterolateral angle bearing a minute process; each anterolateral margin slightly concave; humeri broadly rounded; each posterolateral margin sinuous; posterior margin straight ( Fig. 9 View FIGURES 9–20 ). Apical angle of each corium reaching abdominal segment VI; membranes not surpassing abdominal margin posteriorly; membranes hyaline, with grayish maculae ( Figs 2 View FIGURES 1–8 , 9 View FIGURES 9–20 ). Evaporatorium surrounding peritreme on each metepisternum and restricted to spiracle margin on each mesepimeron ( Fig. 13 View FIGURES 9–20 ). Tibiae sulcate dorsally.

Abdomen. Connexivum exposed. Abdominal spiracles concolorous to abdominal sternites ( Fig. 10 View FIGURES 9–20 ).

Male genitalia. Pygophore rectangular in dorsal view, wider than long ( Fig. 14 View FIGURES 9–20 ). Genital cup opened posterodorsally, genital cup striate ( Figs 14-15 View FIGURES 9–20 ).

Ventral rim concave in ventral view ( Fig. 16 View FIGURES 9–20 ); infoldings of ventral rim robust, produced dorsally, U-shaped medially ( Fig. 15 View FIGURES 9–20 ); densely punctate. Segment X almost twice as long as wide, with a less sclerotized median line ( Fig. 15 View FIGURES 9–20 ). Crown of parameres (p) directed dorsally ( Fig. 17 View FIGURES 9–20 ), crown apically rounded and placed at an oblique angle to stem; lateral margin bearing scale-like microsculptures ( Fig. 17 View FIGURES 9–20 ). Phallotheca (ph) twice as long as wide ( Figs 18–20 View FIGURES 9–20 ); phallotheca smooth; vesica (v) blade-like, surrounded by membranous conjunctiva (cj); ductus seminis distalis (dsd) shorter than vesica, its apex bent ventrally ( Figs 18–20 View FIGURES 9–20 ).

Female genitalia. Gonocoxites VIII (gc8) tumid, as long as wide, facing posteriorly ( Figs 21–22 View FIGURES 21–23 ); mesial margins straight, juxtaposed; posterior margin convex; mesial and posterior margins setose ( Fig. 21 View FIGURES 21–23 ). Gonocoxites IX (gc9) flat, twice as wide as long; anterior margin concave. Laterotergites VIII (la8) triangular; posterior margin smooth; spiracle present. Laterotergites IX (la9) flat, blunt apically, not surpassing tergite VIII. Segment X rectangular, longer than wide. Gonapophyses IX (g9) with 1+1 triangular sclerotized areas, placed along with elliptical chitinellipsen (ch) ( Fig. 23 View FIGURES 21–23 ). Median duct of vesicular area (va) conical; ductus receptaculi distal (drd) ¾ as long as vesicular area; posterior annular flange (paf) wider than anterior annular flange (aaf); capsula seminalis (cs) globose, with one process ( Fig. 23 View FIGURES 21–23 ).
