Description

Figs 82, 83, 84

Male: (Fig. 82a, b) Medium-sized, total length 12.07-13.69 mm (mean 13.19 mm, Suppl. material 2), slender. COLORATION: Brown. Head brown to dark brown; pale brown patch between eye and ocellus; medial stripe on postocular lobe. Pronotum either entirely dark brown or posterior pronotal lobe and scutellum orangish. Legs dark brown, with inconspicuous lighter-colored bands. Abdomen yellowish. VESTITURE: Sparsely setose. Head short, recumbent setae on entire surface; very short, erect, spine-like setae on dorsum, denser on anterior lobe; few moderately long, erect, fine setae on ventral surface. Pronotum with sparse, recumbent setae and short, erect setae over dorsal surface; denser, recumbent setae on lateral surface and pleura, intermixed with short, erect setae; scutellum with erect and recumbent setae. Legs with sparse setation on femora and moderately dense setation on tibiae. Corium and clavus with short, recumbent or erect setae. Abdomen with moderately dense, short recumbent setae, intermixed with sparse, short to long, erect setae. STRUCTURE: Head: Cylindrical, L/W = 2.48. Postocular lobe long; in dorsal view distinctly narrowing through anterior 2/3, posterior 1/3 constant, tube-like. Eye moderately sized; lateral margin much wider than postocular lobe; dorsal margin attaining postocular transverse groove, ventral margin removed from ventral surface of head. Labium: I: II: III = 1: 1.6: 0.4. Basiflagellomere diameter larger than that of pedicel. Thorax: Anterolateral angle bearing small, somewhat acute projection; medial longitudinal sulcus evident throughout, deepening posteriorly. Posterior pronotal lobe with rugulose surface; disc distinctly elevated above humeral angle; humeral angle armed, with dentate projection. Scutellum moderately long; apex angulate. Legs: Slender. Hemelytron: Slightly surpassing apex of abdomen, not more than length of abdominal segment seven; quadrate cell small, elongate; Cu and M of cubital cell subparallel. GENITALIA: (Fig. 83) Pygophore: Elongate ovoid; lightly sclerotized expansion below paramere; not expanded laterally in dorsal view. Medial process cylindrical; slender; long, much longer than paramere; laterally compressed towards apex; semi-erect; nearly straight, curvature slight; apex in posterior view acute, with small hooklike projection. Paramere: Cylindrical; moderately long, reaching about mid-point of medial process; directed posteriad; not distinctly curved; apical part not enlarged. Phallus: Dorsal phallothecal sclerite shield-shaped; sclerotization reduced (yet not absent) on dorsal surface close to posterior margin of foramen; apical portion of phallothecal sclerite gradually tapering, distinctly keeled medially, laterally flat, not forming angle; apex rounded; posterior margin of foramen nearly straight. Struts not attached to dorsal phallothecal sclerite; apically not evident or missing; basally separate throughout. Basal plate arm robust; basally fused; in lateral view slightly curved; bridge extremely short; extension of basal plate well expanded laterally onto arm, covering more than 1/2 of arm, curved.

Female: (Fig. 82c, d) Different from male as outlined below. Larger than male, total length 14.52-17.41 mm (mean 16.23 mm, Suppl. material 2). Dorsal surface, including hemelytron, lighter colored, nearly uniformly pale brown; quadrate cell and proximal margin of postcubital cell yellowish; lateral and ventral surfaces yellowish; legs without or with inconspicuous bands. Basiflagellomere subequal in diameter to pedicel. Process on humeral angle spinous, long.

Diagnosis

The posterior pronotal lobe usually orangish-brown; the medial process rather long, much longer than paramere; and the anterior side of medial process keeled medially at apex. In females the dorsal surface is nearly uniformly brown, the lateral and ventral surfaces yellowish, and the quadrate cell and proximal margin of postcubital cell yellowish.

Distribution

South America (Fig. 84). Countries with records: Bolivia, Ecuador and Peru
