Total length 5.51.

Head: Brown, shiny, coriaceous, with short recumbent and long erect setae dorsally. Head length 1.18, width 0.83. Postocular length 0.43. Eyes not surpassing the dorsal margin of head in lateral view. Ocelli placed at level of an imaginary line passing the posterior border of eyes. Interocular width 0.40, interocellar width 0.24. Labium pale brown with erect setae, extending to metacoxae. Labial segment lengths: I 0.77, II 0.74, III 0.72, and IV 0.34. Antenna pale brown, distiflagellomere with a wide sub-basal yellowish band; setae abundant, short, and recumbent. Antennal lengths: scape 0.46, pedicel 1.08, basiflagellomere 0.96, and distiflagellomere 1.01. Length of pale band on distiflagellomere 0.34.

Thorax: Pronotum brown, anterior pronotal lobe darker, posterior lobe with irregular longitudinal pale stripes, each humeral angle with a whitish spot; collar with scattered punctures, delimited posteriorly by a punctate sulcus, punctures larger on posterior lobe; anterior and posterior lobes with short recumbent setae, and anterior lobe with long erect setae. Collar length 0.08, anterior lobe length 0.53, posterior lobe length 0.48; anterior lobe width 0.86, posterior lobe width 1.34. Pleurae brown, acetabular areas paler, punctate, with short recumbent setae. Evaporative area extended. Scutellum brown, apex paler, pruinose, punctate, with short recumbent and long erect setae, as on anterior pronotal lobe. Hemelytra pale brown, costal margin pale on proximal three-quarters, apex of corium darker, with a subapical whitish spot and an inner pale spot; setae short and recumbent; membrane irregularly brown, with an apical pale spot, veins paler (Fig. 36 C). Legs: Coxae, protrochanter, profemur, except distally, and a subapical band on meso- and metafemur brown, remainder of legs pale brown, apex of tibiae, tarsi, and pretarsi darker (Fig. 33 F); setae semi-erect, longer on profemur. Profemur with spines restricted to apical two-thirds. Protibia slightly curved.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore (Fig. 34 M, N) rounded, declivent and truncate posteriorly in lateral view; anterior margin of dorsal aperture subquadrangular, inner projections elongate, more pronounced posteriorly. Parameres: inner projections broad (Fig. 34 O, P). Aedeagus: vesica with spines laterally, and with two sclerotized lobes with many spines anteriorly; processus gonopori long and slender.
