Postocular region with abundant long and brown setae. Antennal length 8.37– 9.55 (mean = 8. 65), ratio of segments' lengths ca. 1: 0.60: 0.13: 0.35. Antennal tubercle with anteriorly directed spine at base. Antennal segment I light brown, except basally and apically brown, segment II and III brown. Width of eyes 0.13–0.21 (mean = 0.16), interocular space 0.33–0.42 (mean = 0.38). Genae protruded, light brown. Labrum dark brown. Gula light brown. Rostrum length 1.30–1.60 (mean = 1.49), ratio of segments' lengths ca. 1: 1.47: 0.67. Rostrum segments I and II light brown except brown distally with sparse short setae, segment III brown except dark brown apically. Neck dorsally with 1+1 small setose tubercles. Pronotum length 1.90–2.43 (mean = 2.11), width 0.95–1.23 (mean = 1.09). Anterior lobe brown with small short setiferous tubercles. Median sulcus evident only distally. Posterior lobe granulated and setose, light brown. Posterior edge invaginated. Scutellum smooth brown and setose (Fig. 2 ­N). Sterna glabrous. Fore legs light brown, trochanters with sparse setae, femora light brown except a dark brown ring distally or two small rings, one distally and the other medially, tibia light brown setose, tarsi light brown except segment III brown (Figs. 2 ­O). Median and hind legs light brown, femora slightly incrassate apically, tibia with abundant thin setae, tarsi brown. Pleura brown glabrous. Stridulatory sulcus dark brown and setose (Fig. 2 ­P). Hemelytra length 4.74–5.32 (mean = 5.10), brown. Abdomen length 4.75–5.70 (mean = 5.24), width 1.20­ 2.28 (mean = 1.41). Abdomen visible from above. Connexivum light brown, urotergites light brown and glabrous.

Male: pygophore smooth and setose, without base of median process (Fig. 2 ­Q). Parameres elongate, apically curved with short internal and external setae (Fig. 2 ­R). Apical hook very acute and straight (Fig. 2 ­S). Phallus (Fig. 2 ­T), articulatory apparatus (Fig. 2 ­U)

Female: gonocoxite VIII subquadrangular, abundant setae present (Fig. 2 ­V), laterally expanded, relation between maximal width of gonocoxite and maximal width of gonapophysis 5.3: 1.3. Gonocoxite IX subtriangular, distal abundant long setae present (Fig. 2 ­ W).

Distribution (Fig. 4 ­B): ARGENTINA, BOLIVIA, BRAZIL, GUYANA, and PAN­ AMA.

Observations: New record for Bolivia, new locality records for Argentina and Brazil. The closest species are B. biannulatus and B. misionensis n. sp., but B. femoratus differs in the structure of the male and female genitalia.
