Diagnosis. A distinctive species, most similar to B. hispidus, with the following combination of characters: Scutellum with fine additional setae scattered on disc. Femora with distal third to quarter orange. Mid and hind tibiae mostly orange, with a dark band at two-thirds length.
Description. Head orange, occiput black, frons dark reddish brown posteriorly. Prementum and maxillary palp yellow. Occiput and gena covered with microtomentum, frons covered with microtomentum except large spots lateral to ocelli, face with a thin band of microtomentum below antenna and lunule. Ocellar bristles at level of or just anterior to median ocellus. Subvibrissal and anterior genal bristles about 0.5X length of vibrissa.
Thorax black, mostly covered with microtomentum, proepisternum, a spot on anepisternum covering anterior two-thirds and ventral two-thirds, a spot on katepisternum behind fore coxa, and meron and posterior katepisternum shiny. Mesoscutum sculptured. Scutellum with scattered fine setae dorsally. Halter whitish.
Coxae and most of femora black, basal tips and distal quarter to third of femora orange, trochanters yellow. Fore tibia reddish brown with darker brown band at two-thirds, mid and hind tibiae orange with dark brown band at two-thirds. Tarsi with 2 basal tarsomeres yellow and distal 3 pale brown. Mid tibia with one preapical anterodorsal, 4 subapical bristles. Hind tibia with one small ventroapical bristle.
Wing light brown, white spots around crossveins r-m and dm-cu.
Abdomen with tergites and sternites weakly sclerotized. Syntergite 1+2 with posterolateral corners and a thin band between them strongly sclerotized, tergites 3–4 with a thin posterior band moderately sclerotized. Pleural setae on small discs, about the diameter of spiracles.
Male postabdomen: Sternite 5 narrow, flared posteriorly, posterior margin with a shallow notch medially and interuppted row of setae, anterior apodeme short (Fig. 44). Surstylus paddle-shaped. Hypandrial arms with ventral tab-like structures. Pregonite fused with postgonite. Postgonite with lobes narrowly separated, anterior lobe rounded, posterior lobe pointed. Basiphallus with long epiphallus, narrow, transparent preepiphallus. Distiphallus with strongly curved, spinose dorsal tube, flattened near apex (Fig. 43).
Female postabdomen: Tergite 6 not sclerotized, tergite 7 sclerotized along lateral margins, sternites 6 and 7 sclerotized around margins. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 emarginated anteriorly, covered with microtomentum except anterior corners. Epiproct with short anterior arms, covered with microtomentum except arms, 1 pair of setae. Cerci broad. Sclerites of sternite 8 broad, kidney-bean shaped, posterior three-fifths covered with microtomentum. Hypoproct broad, notched anteriorly, covered with microtomentum except anterior corners on either side of notch. Spermathecae sausage-shaped, about 4X longer than wide, invaginated apically.
