Coloration: Antennae dark, brown basally and light brown distally, VI and VII segments yellowish. Head black, eyes dark brown (Fig. 14). Pronotum dorsally with three colors (Fig. 13), fore lobe toffee-colored, hind lobe red-orange with middle black spot and some small black spots in transverse sulcus. Ventrally, fore lobe black; hind lobe, same color as dorsal part, darkened at contact with fore lobe. Rostrum black. Scutellum black. Hemelytra two colored, basal and exocorial regions red; lighter at distal extremity; remaining parts of hemelytra and membrane dark brown; hind and lateral edge of membrane translucent (Fig. 13). Connexivum narrow, redorange (Fig. 13). Ventral side black; sternites black with narrow and lobed external orange-red band in contact with connexivum; this band broadest in hind sternites close to pygophore. Abdominal spiracles located at limits of black and red-orange regions. Legs black; tarsi yellow. Body glabrous; some hairs in anterior part of head and rostrum (Fig. 15). Antennae (Fig. 16): first antennomere of same length as head, with double pilosity; one, brown, spiny, inclined, shorter than middle of diameter of antennomere; the other with yellow hairs, perpendicular, and longer than diameter of anternnomere. Second antennomere with same type of pilosity, but brown hairs of same length as yellow hairs; also, long setae, twice diameter of antennomere. Third antennomere similar to previous one, but brown setae more evident and length similar or longer than diameter of it. In fourth antennomere, brown hairs missing at extremity. In remaining antennomeres, no brown hairs; yellow hairs recumbent, similar, or longer than the diameter of antennomeres and long setae tilted forward several times (3–5) longer than the diameter of antennomeres. Head (Figs. 14–15) triangular, slightly longer than hind lobe of pronotum. Clypeus slightly longer than mandibular plate; striated transversely in anterior part. Vertex with two fine longitudinal furrows arising at base of clypeus and ending at level of middle of eyes (Fig. 14). Presence of transverse striations between midlongitudinal furrow and towards antennal tubercles and eyes; vertex smooth close to ocelli (Fig. 14). Eyes large, protruding; interocular distance more than twice width of eye. Ocelli large, yellow, with diameter greater than interocellar distance and distance separating them from eyes (Fig. 14). Laterally, eyes not reaching lower edge of head. Posteriorly, under eye, presence of hemispherical protuberance (Fig. 15). In lateral view, striations in front of and below eyes. In middle of lower edge of head, smooth area finishing in small tooth located at bottom edge of eye. Rostrum short; first segment slightly dilated at apex, with longitudinal striations; second segment slightly dilated in middle, with transversal striations; third segment tapered, blunt (Fig. 15). Pronotum nearly smooth; weakly, sparsely, and irregularly striated. Anterior angles blunt. Two paired small, lateral longitudinal impressions in anterior part of fore lobe. Longitudinal furrow distinct, deep in middle; 6–7 strong transversal grooves in this zone, spotted with black. Transverse furrow very distinct over whole length, with several small short longitudinal grooves. Hind border slightly convex. Scutellum with two Y-shaped carinae. Wrinkled depression in middle, skirting above carinae. Outgoing, flat, and smooth lateral tubercle at anterior extremity of carinae. Two very wrinkled areas in the middle of lateral edges of scutellum. Apical prongs strong, long, with internal border lobed and slightly rough at extremity. Hemelytra smooth, extending almost to extremity of abdomen. Membrane wrinkled. Abdomen smooth; finely striated transversely and slightly arched. Legs: prolegs (Fig. 17): coxae with two straight spiny areas separated by smooth zone. Femora slightly thickened, striated transversely, especially in distal zone. Straight spiny zone in basal portion of anterior quarter, ending distally in weak, small teeth. Tibiae straight, thin, with fossula spongiosa extending to just less than one-third of their length. Tarsi long, slightly shorter than half of tibia; dorsally without hairs, ventrally with two types of hairs: one numerous, of same length as the diameter of the tarsomeres; and the other sparse, more than twice as long as diameter. Middle legs (Fig. 18): coxae with single broad median spiny area. Femora slightly thickened; striated transversely in distal zone. Spiny area in basal third of lower edge, ending in blunt teeth, more distinct than in fore femur. Tibiae straight, slender, slightly thickened distally; fossula spongiosa occupying one-third of tibiae. Tarsi long, shorter than middle of tibiae. Pilosity as on fore tarsi, but long hairs scarce. Hind legs (Fig. 19): coxae without spiny area. Femora slender, straight, cylindrical, slightly thickened distally. Tibiae straight, long. Tarsi long; slightly longer than one-third of tibiae and with same type of pilosity as on middle tarsi. Male genitalia (Figs. 20–27): pygophore oblong, posterior margin not sinuous in middle; parameres’ apices removed in resting position (Figs.20–21). Median process of pygophore blunt and broadly triangular (Figs. 22–23). Parameres symmetrical, curved, rounded at apex, and with distal large tooth directed upwards (Figs. 24–25). Phallus simple (Figs. 26–27); phallosoma slightly sinuous in middle of anterior margin; this zone with semicircular sclerotization (Fig. 27); endosoma with a pair of separated and elongated processes.

Female unknown.
