Description.­ Body length 7.66–9.37 (mean = 8.20). Head smooth, light brown, with scarse light brown setae ( Fig. 3 View FIGURE 3 ­A). Length 1.07–1.37 (mean = 1.25), width 0.67–0.73 (mean = 0.70). Antennal tubercle with granule at base. Antennal length 7.59–9.45 (mean = 8), ratio of antennal segments' lengths ca. 1: 0.70: 0.24: 0.17. Antennal segment I light brown except basally and distally brown, segment II–IV brown, with setae. Width of eyes 0.15–0.20 (mean = 0.18), interocular space 0.30–0.35 (mean = 0.33). Genae protruded light yellow. Gula brown. Rostrum length 1.33–1.37 (mean = 1.35), ratio of rostrum segments' lengths ca. 1: 1.42: 0.92. Rostrum segments I and II light brown, darker distally, with scarse short setae; segment III brown with abundant setae dorsally. Neck with small setose tubercles. Pronotum length 1.70–2.40 (mean = 1.93), width 1.07–1.17 (mean = 1.09). Anterior lobe light brown with setiferous short tubercles. Median sulcus evident only distally. Posterior lobe brown granulated, posterior edge not invaginated ( Fig. 3 View FIGURE 3 ­B). Sterna glabrous. Scutellum smooth ( Fig. 3 View FIGURE 3 ­C). Fore legs light brown, femora light brown except two brown rings medially and apically, tibia light brown except a basal and dorsal brown spot with sparse thin setae, tarsi light brown, except segment III brown ( Fig. 3 View FIGURE 3 ­D). Median and hind legs light brown, femora slightly incrassate apically, tibia with abundant thin setae, tarsi brown. Propleura setose. Stridulatory sulcus light brown and setose ( Fig. 3 View FIGURE 3 ­E). Hemelytra length 4.24–5.63 (mean = 4.67), brown. Abdominal length 4.36–5.44 (mean = 4.70), width 1.00–1.23 (mean = 1.10). Abdomen visible from above. Connexivum light brown. Urotergites light brown and glabrous.

Male: pygophore glabrous and smooth, two acute projections distally ( Fig. 3 View FIGURE 3 ­F). Parameres elongate, apically curved, long internal setae present ( Fig. 3 View FIGURE 3 ­G). Base of pygophore median process thin, setose, apical hook acute ( Fig. 3 View FIGURE 3 ­H). Phallus ( Fig. 3 View FIGURE 3 ­I), articulatory apparatus ( Fig. 3 View FIGURE 3 ­J).

Scale line: 1mm, Figs. A­E, M­Q; scale line: 2mm, Figs. F­L, R­W.

Female: gonocoxite VIII subtriangular, sparse setae distally ( Fig. 3 View FIGURE 3 ­K), laterally expanded, relation between maximal width of gonocoxite and maximal width of gonapophysis 2.8: 1. Gonocoxite IX subquadrangular, distal long setae present ( Fig. 3 View FIGURE 3 ­L).

Distribution ( Fig. 4 View FIGURE 4 ­C): ARGENTINA, BRAZIL, MEXICO, and PANAMA.

Observations: First record for Argentina, and new locality records for Brazil, Mexico, and Panama. The closest species are B. femoratus and B. misionensis n. sp., but B. biannulatus differs in the shape of the posterior lobe of the pronotum.
