Description

Figs 36, 37, 38

Male: (Fig. 36a, b, c, d) Medium-sized, total length 12.64-14.37 mm (mean 13.61 mm, Suppl. material 2); slender. COLORATION: Nearly entire surface medium dark brown; apices of femora dark colored; abdomen light brown to yellowish-brown. VESTITURE: Densely setose. Body surface covered with short, adpressed to recumbent setae, dorsal setae on head and pronotum golden, shining; ventral surface of head and abdomen with longer, erect setae; sometimes setae covered with white waxy exudation. Dense, long, erect setae on paramere; bush of short, erect, spine-like setae on posterior surface of medial process. Corium and clavus with short, recumbent setae. STRUCTURE: Head: Cylindrical, L/W = 2.63. Postocular lobe long; in dorsal view anteriorly gradually narrowing, posterior portion constant, slightly narrower. Eye prominent; much wider than postocular lobe; dorsal and ventral margins removed from surfaces of head. Labium: I: II: III = 1: 2.0: 0.4. Basiflagellomere diameter slightly larger than that of pedicel. Thorax: Anterolateral angle bearing small projection; medial longitudinal sulcus shallow near collar, deepening posteriorly. Posterior pronotal lobe with rugulose surface; disc about same level as humeral angle; humeral angle armed, with dentate or spinous process. Scutellum long; apex blunt, not projected. Legs: Slender. Hemelytron: Slightly surpassing apex of abdomen, not more than length of abdominal segment seven; quadrate cell small, relatively broad; Cu and M of cubital cell converging towards R. GENITALIA: (Fig. 37) Pygophore: Ovoid; slightly expanded laterally near base of paramere in dorsal view. Medial process triangular; slender; long; anteroposteriorly compressed; semi-erect; curved at middle; apex in posterior view acute, with small hooklike projection. Paramere: Cylindrical; moderately long, slightly exceeding medial process; directed posteriad, slightly curved towards medial process; basally narrower; curved ventrad; apical part very slightly enlarged. Phallus: Dorsal phallothecal sclerite somewhat pandurate, medially strongly constricted; laterally with dorsally directed small sharp projection at mid-portion; apical portion of phallothecal sclerite gradually tapering, lateral margin narrowly angulate, angulation ending anteriorly in sharp, dorsad projection; apex rounded, medially emarginate; posterior margin of foramen inversely V-shaped. Struts attached to dorsal phallothecal sclerite; apically separate, connected by bridge; basally almost completely fused. Basal plate arm moderately robust; separate; converging; in lateral view severely curved, nearly semi-circular; bridge short; extension of basal plate expanded onto arm.

Female: (Fig. 36e, f) Similar to male, except for the following. Larger than male, total length 17.21-18.32 mm (mean 17.85 mm, Suppl. material 2). Eye moderate size, smaller than in male.

Diagnosis

Can be readily recognized by the uniformly brown dorsal coloration; the darkened tibial apex; the humeral angle elevated to level of disc; the dorsal setae on head and pronotum appearing somewhat golden, shining when viewed under magnification. Males can also be recognized by the gradually enlarged paramere; the triangular medial process, curved slightly posteriad in the middle, apex with a hooklike projection; and the dorsal phallothecal sclerite with short, dorsad projections sub-laterally.

Etymology

The species epithet indicates the somewhat reddish tone of the coloration.

Distribution

South America (Fig. 38). Countries with specimen records: Bolivia, Brazil, Ecuador and Peru.
