The female 7th sternite is distinctly sclerotized, the 8th tergite is narrower, and the 10th tergite is narrow, strongly convex posteriorly and with fewer setulae.

Comments. The wing differences between the types of B. braziliensis and B. shropshirei were noted by Reemer (2010) as well, where he stated on page 186 that “These specimens were compared with the holotype of B. braziliensis [...] However the following differences were noted (in parentheses the character state in the Mapane specimens): wing with bare areas on cells r, bm and cu p (entirely microtrichose), wing with vague yellowish anteromedial blotch (infuscated on basal half), pterostigma clearly darker than 2nd costal cell (pterostigma and 2nd costal cell of same yellowish brown colour). [...] they are identified as O. shropshirei, with which they agree quite well”.
