Fore and mid legs brown with black and ocher stripes, hind tibia ocher, and tarsomeres ocher, with the last segment having the distal third brown. Head taller than wide, eyes occupying a third of the cephalic capsule; space between the eyes as wide as 1.5 times the width of one of the eyes; medial carina moderately protruding in the middle of the eyes in lateral view, exceeding about a third of the length of the eyes, projecting almost straight, without curving downwards; scutellum narrow, slightly widened; fascial carinae straight and parallel, protruding and rounded in lateral view; lateral ocelli located near the fork of the frontal costa ( Fig. 55C). Antennae incomplete. Thorax. Anterior margin of the pronotum almost straight; prozonal carinae developed, pronotal apex pointed in dorsal and lateral views ( Fig. 55B). Median carina subelevated; internal lateral carinae almost straight in dorsal view; external lateral carinae slightly denticulated and curved ( Fig. 55B); infrascapular area widened and ovoid in lateral view, longer than wide ( Fig. 55A).

Abdomen unmodified. Tenth tergite constricted; cerci conical tapering towards the distal section. Ovipositor valves with normal development and covered with bristles. Subgenital plate quadrangular, nearly as long as wide, posterior margin rounded with a small triangular extension in the middle. The epiproct was not possible to examine.

Male. Unknown.

Measurements (in mm). CFP: 9. PL: 9. HL: 4.5.

Remarks. B. lutosa comb. nov. is the only species previously described. It was allocated within Metrodora , and its classification has not changed until now. The type locality of B. lutosa was stated solely as “ Brazil ” ( Fig. 55D), but Pavón-Gonzalo et al. (2012) mention that it is found in Venezuela. However, this was possibly a confusion on the part of the authors since no previous record cites the species for that country. No additional specimens have been recorded since its original description.
