General color brownish to blackish with second segment of rostrum, except on apex, irregular spots on femora, a sub-basal and larger sub-apical rings on fore and middle femora, hind tibia, except on basis, which are brighter to yellowish; middle and hind tarsi somewhat brighter as well. Integument covered with bright erect bristles, curved and erect hairs (Figs. 6–10). HEAD: first antennal segment with a long, erect conspicuous bristle at middle third of medial face; ocelli very small; eyes with erect short bristles. THORAX: hemelytra short, reaching apical portion of tergite III [second visible] or basal third of tergite IV, membrane glabrous; hind wings short. Scutellum with two lateral swellings covered with numerous yellowish hairs; basal mid portion moderately excavated; apex pointed (Figs. 6–8). ABDOMEN: dorsal abdominal scent glands visible between tergites III–IV and IV–V; on distal portion of the latter, medially, a small tubercle covered with numerous pale hairs is present. Lateral posterior margins of tergites projected slightly, more pronounced on tergites V and VI; last tergite (VII) with two short rounded prominences laterally (Figs. 6–7, 9–13). MALE GENITALIA: pygophore sub-rectangular (Figs. 12–15), median process of pygophore triangular, not visible on ventral view (Fig. 16). Parameres apices close to each other in resting position (Fig. 15); symmetrical, moderately curved, covered with strong hairs on distal half, with a rounded apex, a keel on medial surface of approximately distal third, which ends as a rounded subapical protuberance; near the latter, on distal portion, a subspherical somewhat small structure is visible; a smaller round protuberance is present adjacent to basal portion of the medial keel (Figs. 17–19). Phallus simple (Figs. 20–21); articulatory apparatus with long pedicel (Figs. 20–21); dorsal phallotheca plate somewhat subpentagonal (Figs. 21, 24); basal plates struts larger in base, curved, connected apically (Figs. 21, 24–26). Endosoma (Figs. 21, 27–30) with a pair of basal processes which includes tooth-like structures (Figs. 21, 27–28), in which distal portion is contiguous with other pair of processes formed by fine thickening of endosoma (Figs. 21, 29); laterally to these, another pair of discrete elongated thickening of endosoma (Fig. 21); at the apex of endosoma, a pair of rounded processes of conjunctive (Fig. 30).

Measurements (in mm): Total length: 13.2–14.0; head: total length: 2.5; maximum width across the eyes: 1.4–1.5; anteocular length: 1.5–1.6; postocular length: 0.6; interocular space: 0.8–0.9; antennal segments: I: 0.9; II: 1.3; III: 0.4; IV: 0.55–0.6; rostral segments: I: 1.0–1.1; II: 1.1–1.2; III: 0.6.
