Fig. 2
M). 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 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.

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.
