Diagnosis

Male

Eye bridge with four facet rows ( Fig. 10A ); wing 2.8 times as long as wide; ejaculatory apodeme about the same length as the aedeagus, with anterior margin rounded, gonocoxal apodeme projecting anteriorly; surstyli with six apical tenacula; aedeagus digitiform, tapering towards the apex, paramere digitiform, tapering towards the apex and longer than aedeagus. This species shares the same number of apical tenacula in the surstyli as B. gorgona sp. nov. Still, it can be easily differentiated by the length of the hypandrium (hypandrium length is shorter than aedeagal width in B. chuspi sp. nov., hypandrium length is longer than aedeagal width) B. gorgona ) and the shape of the epandrium (U-shaped in B. chuspi , rectangular in B. gorgona ).

Female

Unknown.

Etymology

The specific name ʻ chuspi ʼ derives from the Quechuan word ʻchuspiʼ meaning fly. Species name to be treated as a name in apposition.

Description

MEASUREMENTS. In mm (n = 13). Wing length: 2.76 (2.50–3.00), wing width: 0.94 (0.90–1.00); head length: 0.44 (0.42–0.45), head width: 0.46 (0.46–0.48); antennal segments: scape: 0.12 (0.11–0.13), pedicel: 0.07 (0.07–0.08), flagellomere 1: 0.12 (0.11–0.12), flagellomeres 2–13: 0.14 (0.14–0.15), flagellomere 14: 0.16 (0.16–0.16); palpal segment 1: 0.06 (0.05–0.06), palpal segment 2: 0.06 (0.06–0.07), palpal segment 3: 0.08 (0.08–0.08), palpal segment 4: 0.11 (0.10–0.12).

Holotype male

HEAD ( Fig. 10A ). 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; frontal patch of alveoli not divided, rectangular with concave lateral margins, lower margin straight, upper margin partially divided in the middle. Antennal scape is about two times as long as the pedicel, cylindrical; the pedicel is spherical; flagellomeres are asymmetrical and nodiform, with scattered setae on the basal half surface, flagellomere 14 with terminal apiculus being two times as long as the elongated basal part of the flagellomere; ascoids about the same length as the flagellomere carrying them, and about two times as wide as the width of flagellomere. Palpal segments cylindrical, palpal segment 4 apically pointed, palpal proportions: 1.0:1.0:1.3:1.8; 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 two 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 basal to the level of M 1+2 and joining R 4; fork of M 1+2 weakly sclerotized; R 5 ending at the wing apex; CuA 2 ending at wing margin.

TERMINALIA ( Figs 10B–C , 11 ). Hypandrium is a distinct band that connects the gonocoxites, plate-like; gonocoxites are cylindrical, about two-thirds the length of the gonostyli, gonostyli digitiform; gonocoxal apodeme fused; gonocoxal lobe with 5–6 setae on each side, spine of the gonocoxal lobes present; aedeagus digitiform, with rounded apex, ending at about the same level as the paramere, paramere digitiform, tapering towards apex, with pointed apex; ejaculatory apodeme with anterior margin rounded, about the same length as the aedeagus; epandrium U-shaped; hypoproct U-shaped, and covered in small setulae, epiproct broader and shorter than hypoproct; surstyli conical narrowing towards the apex, with six apical tenacula, tenacula with rounded apex.
