Coloration. General coloration black to brownish or reddish brown (Figs 1–2); head, including eyes and antennae black (Figs 3–4); scutellum reddish; hemelytra black or dark brown, with a yellowish spot on external and mid-distal portions of corium, reaching adjacent part of membrane, mainly in basal portion of distal cell of membrane (Figs 1–2); fore femur black to brownish, and with very faint, small, almost imperceptible, and incomplete yellowish middle annulus; mid and hind femora black, with medial yellowish annulus, which is approximately 1/8 as long as each femur, respectively; tibia and tarsi black. Abdomen: reddish on segments II–V, somewhat darkened on connexivum and distal segments, in holotype; in paratype, sternites II–III and lateral portion of IV, reddish-brown, the remaining darkened.
Structure and vestiture. Head (Figs 3–4): elongate, 1.6 to 1.8 times as long as wide across eyes; integument shiny, with sparse long and short, straight or somewhat curved blackish setae and hairs; these latter much denser, forming pubescence of long blackish hairs on postocular portion, dorsally, and ventrally on gula. Anteocular portion slightly longer than postocular; the latter, in dorsal view, narrowing gradually to form collum. Antenna inserted at level of upper third of eye; antennal segments I and II [other absent] with straight or curved darkened sparse setae; first segment (scape) approximately two times as long as head and four times as long as second antennal segment, somewhat enlarged. Postantennal spines small, somewhat acute. Eyes globose, projecting laterally, somewhat prominent in dorsal view, reaching dorsal margin of head at interocular sulcus on approximately its mid portion; not reaching ventral margin of head, which is far from inferior margin of the eye. Ocelli elevated, much closer to eyes than to each other.
Thorax with shiny integument; pronotum covered with dense, blackish hairs on anterior lobe; posterior lobe with sparse, short setae, forming a faint mid-longitudinal line in hind lobe, where these setae are clearer, yellowish to whitish; disc of posterior lobe smooth, with faint horizontal depression across humeral angle; propleura covered with darkened hairs in holotype and almost glabrous in paratype; meso- and metapleura with sparse long darkened hairs in holotype and almost glabrous in paratype; thoracic sterna with sparse long darkened hairs somewhat numerous on center of meso- and metasternum. Scutellum reddish, subtriangular, with median shallow depression; apex blunt in holotype, acute in paratype, with a few hairs on central portion, which are somewhat more numerous on lateral margins and apex.
Legs: slender and elongate; coxae and specially trochanters with sparse long straight blackish hairs and dense erect brush-like setae ventrally; fore and hind femora and tibiae straight (Fig. 5); mid femora and tibiae somewhat curved in dorsal view; femora thickened basally in proportion of approximately 1.7 times the thickness on median portion of the segment; femora slightly dilated subapically too, with sparse long straight blackish hairs and dense erect brush-like setae ventrally, which are quite longer on basal portion, and restricted to the latter on hind femur (Fig. 5); fore tibiae somewhat enlarged at apex, with small apical spur on anterior surface of segment; mid tibiae with uniform thickness; hind tibiae (Fig. 5) somewhat enlarged in basal half and narrowing a little to apex; all tibiae with sparse long straight blackish hairs and shorter dense erect brush-like brownish setae much more numerous on ventral and lateral portions on fore and mid tibiae, and along all portions on hind tibiae (Fig. 5); short setae are present too; tarsi with brownish setae.
Hemelytra long, surpassing abdomen by about half length of membrane and quarter of length of body; corium covered with curved adpressed, brown to yellow-brownish, bristlelike setae; membrane glabrous (Figs 1–2).
Abdomen: elongate; spiracles rounded, somewhat clear; sternites with integument shiny with long sparse fine yellowish hairs; subtriangular patches of whitish minute short setae on mid-lateral portions of sternites III and IV.
Female external genitalia (Figs 6–7). Syntergite 9/10 with very long sparse strong blackish hairs; first gonapophysis with strong setae on anterior margin.
Etymology. The new species is named in honor of the entomologist Roberto da Rocha Salgado, because of his great interest and knowledge in entomology, particularly in Heteroptera.
Distribution. Brazil (Rio de Janeiro).
