Diagnosis

Male

Eye bridge with four facet rows ( Fig. 14A ); wing 2.5 times as long as wide; ejaculatory apodeme short, with anterior margin straight, shorter than the aedeagus ( Fig. 14B, D ); gonocoxal apodeme projecting anteriorly; surstyli with six apical tenacula ( Fig. 14B–C ); aedeagus digitiform, with rounded apex, paramere digitiform and longer than aedeagus. This species shares the same number of apical tenacula in the surstyli as B. gorgona sp. nov. but it can be easily differentiated by the length of the hypandrium (hypandrium length is longer than aedeagal width in B. gorgona , hypandrium length is shorter than aedeagal width in B. chuspi sp. nov.), and the shape of the epandrium (rectangular in B. gorgona , U-shaped in B. chuspi ).

Female

Unknown.

Etymology

The specific name ʻ gorgona ʼ derives from the name of the type locality, Gorgona Island. To be treated as a name in apposition.

Description

MEASUREMENTS. In mm (n = 3). Wing length: 2.27 (2.204–2.55), wing width: 0.90 (0.85–0.96); head length: 0.40 (0.40–0.40), head width: 0.45 (0.45–0.45); antennal segments: scape: 0.10 (0.10–0.10), pedicel: 0.06 (0.06–0.06), flagellomere 1: 0.11 (0.11–0.12), flagellomeres 2–9: 0.12 (0.12–0.12), palpal segment 1: 0.05 (0.05–0.06), palpal segment 2: 0.07 (0.07–0.07), palpal segment 3: 0.07 (0.07–0.07), palpal segment 4: 0.08 (0.08–0.08).

Holotype male

HEAD ( Fig. 14A ). 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, rectangular with the lower and upper margins straight. Antennal scape is about two times as long as the pedicel, cylindrical; pedicel spherical; flagellomeres are asymmetrical and nodiform, with scattered setae on the basal half surface, apical flagellomeres absent, the maximum number of flagellomeres present in examined material: 9; ascoids absent in examined material. Palpal segments cylindrical, palpal segment 4 apically pointed, palpal proportions: 1.0:1.3:1.3:1.5; labium without any strong sclerite; labella not bulbous with 3–4 setae on the 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

; fork of M

1+2

weakly sclerotized; R

ending at the wing apex; CuA

2

ending at wing margin.

TERMINALIA ( Fig. 14B–D ). 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 lobes without anterior projection, fused, and with 4–5 setae on each side; aedeagus digitiform with rounded apex, ending slightly after the apex of the paramere, paramere digitiform, evenly tapering towards apex, with pointed apex; ejaculatory apodeme with anterior margin straight, about the same length of the aedeagus; epandrium rectangular; hypoproct V-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.
