(Figs. 6.1–6.14) Description: Body length 1.1–1.6 mm (males), 1.2–1.7 mm (females). Generally similar to B. abundantia . Head: Anterior fronto-orbital seta 0.3x as long as posterior seta, extremely weak, almost indistinguishable from setulae. Wing: Distance between radial fork and r-m 5x length of r-m; dm-cu 2x length of r-m and distance between crossveins 2x length of dm-cu. Legs: Ventral surface of male mid tibia with a comb of 9 stout setae increasing in size distally followed by a large apical seta on distal half; ventral surface of female mid tibia only with large apical seta. Male abdomen and terminalia: S5 with a pair of rounded posteromedial lobes posteroventrally covered with spicules, and with 2 short and tight rows of ventromedially directed setae anterior to lobes; anterior row with 7 setae, half as strong as posterior row of 4 setae. Anteroventral process on right side of epandrium long and of uniform width; left thin long sclerite probably homologous with left anteroventral process; both articulating ventrally with anterior hypandrial apodeme. Cercus thin, apically tapering. Surstylus J-shaped with rectangular medial lobe and long slender lateral process. Distiphallus WS quadrate base upright and long; LFS basally narrow, apically spatulate; FDS form a dorsal arch weakly resembling a tongue; SDS distally desclerotized to almost membranous, leaf-shaped. Female abdomen and terminalia: S7 posteriorly collapsed; posteriorly with 1 row of setae of alternating size on each half and anteriorly with several small scattered setae. Ventral edge of each half of T8 long, with 1 seta. S8 thin and very well sclerotized, arched from side to side. Cercus short, pear-shaped, with medial preapical stout hooked seta. Each spermatheca with 1 large hemispherical pit and 1 small shallow pit. FIGURES 6.1–6.5.

Etymology: This name refers to the antler-shaped surstylus (Latin ‘ramus’: branch, antler). Comments: B. ramus is widespread at low elevations across South America. The 2 tight rows of setae on S5 usually seem to form a medial horn when observed under a dissecting microscope. The cercus is short and pointed when compared to B. abundantia , though not as small as B. fractacincta . The cerci are normally flexed inwards. The hypandrial arms are uniformly broader than in B. abundantia , B. magna , B. pinna , and B. robustora , but not as broad as those of B. fractacincta .
