Diagnosis
Male
Eye bridge with four facet rows ( Fig. 15A View Fig ); wing 2.2 times as long as wide; ejaculatory apodeme cylindrical and hour-glass-shaped ( Fig. 15B View Fig ), about the same length as the aedeagus; gonocoxal apodeme fused; surstyli with one tenaculum ( Figs 15C–D View Fig , 16B View Fig ); aedeagus digitiform, out curved and evenly tapering towards apex ( Fig. 16 A View Fig ). This species shares the same number of apical tenaculum in the surstyli (one apical tenaculum) with B. uncinatum and B. paulistensis . Still, it can be easily differentiated by the number of rows of facets in the eye bridge (three in B. insperatum sp nov., four in B. uncinatum , and five in B. paulistensis ).
Female
Unknown.
Etymology
The specific name ʻ insperatum ʼ derives from the Latin word ʻ insperatus ʼ (neuter ʻ insperatum ʼ), meaning unexpected, referring to unexpectedly finding a new species while looking in the collections. Name to be treated as an adjective.

Description
MEASUREMENTS. In mm (n = 1). Wing length: 2.87, wing width: 1.29; head length: 0.52, head width: 0.61; antennal segments: scape: 0.14, pedicel: 0.09, flagellomere 1: 0.18, flagellomeres 2–12: 0.20; palpal segment 1: 0.07, palpal segment 2: 0.10, palpal segment 3: 0.10, palpal segment 4: 0.20.
Holotype male
HEAD ( Fig. 15A View Fig ). A little wider than long; eye bridge contiguous, with four rows of facets, interocular suture absent; post-ocular alveoli not enlarged and non-distinguishable from the remaining alveoli on the head; the frontal patch of alveoli not divided, triangular with lower margin straight. Antennal scape about two times the length of the pedicel, cylindrical; pedicel spherical, smaller than scape; flagellomeres asymmetrical and nodiform, with scattered setae on the basal half surface, apical flagellomeres absent in examined material, the maximum number of flagellomeres present is 12; ascoids rectangular and broad, about the same length, and about two times as wide as flagellomere carrying them. Palpal segments cylindrical, palpal segment 4 apically pointed, with bilobed apex, palpal proportions: 1.0:1.4:1.4:2.8; labium without any strong sclerite; labella not bulbous with 3–4 setae on outer margin.
THORAX. Without allurement organs; all coxae with a stripe of three to five rows of alveoli. Wing length about 2.2 times its width; wing membrane brown-hyaline; alveoli distributed uniformly on wing membrane; subcostal vein short ending beyond the origin of R 4; fork of R 2+3 at the basal to the level of M 1+2 and joining R 4; fork of M 1+2 weakly sclerotized, almost appears as it is not joining; R 5 ending at the wing apex; CuA 2 ending at wing margin.
TERMINALIA ( Figs 15B–D View Fig , 16 View Fig ). Hypandrium is a distinct band that connects the gonocoxites, plate-like; gonocoxites cylindrical, longer than gonostyli, gonostyli conical, with rounded-blunt apex; gonocoxal apodeme not anteriorly projected; gonocoxal lobes posteriorly projected on each side, each lobe with five setae; aedeagus digitiform and out curved, evenly narrowing towards the apex, apex rounded, and ending beyond the apex of the paramere, paramere digitiform ( Fig. 16A View Fig ), broader than aedeagus, with apex rounded; ejaculatory apodeme with anterior margin round ( Fig. 16A View Fig ), about the same length of the aedeagus; epandrium not discernable in examined material, but appears U-shaped; hypoproct tongue-shaped ( Fig. 15D View Fig ), and covered in small setulae, epiproct shorter than hypoproct; surstyli conical, slightly tapering towards the apex and curved ventrally, with one apical tenaculum, tenaculum with rounded apex.
