Diagnosis

Male

Eye bridge with three facet rows ( Fig. 8A ); wing 2.1 times as long as wide; ejaculatory apodeme ovoid, with anterior margin straight, shorter than the aedeagus; gonocoxal apodeme projecting anteriorly; surstyli with two apical tenacula; 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. asymmetricum sp. nov. but it can be easily differentiated by the shape of the paramere (digitiform with pointed apex in B. asymmetricum , digitiform and with rounded apex in B. bitenacula sp. nov.), and the length of the paramere (shorter than the aedeagus in B. bitenacula , longer than the aedeagus in B. asymmetricum ).

Female

Unknown.

Etymology

The specific name derives from the Latin word ʻ bi ʼ meaning two, and ʻ tenacula ʼ. It makes reference to the two apical tenacula present in the surstyli. To be treated as a noun in apposition.

Holotype male

HEAD ( Fig. 8A ). A little wider than long; eye bridge contiguous, with five 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 the lower margin straight, upper margin convex. Antennal scape slightly longer than the pedicel, cylindrical; pedicel spherical; 14 flagellomeres asymmetrical and nodiform, with scattered setae on the basal half surface, apical flagellomere with terminal apiculus; ascoids about the same length as the flagellomere carrying them, and about two times wider than the width of flagellomere carrying them. Palpal segments cylindrical, palpal segment 4 apically pointed, palpal proportions: 1.0:1.8:1.6:1.4; 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 2.1 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 normally sclerotized; R 5 ending at the wing apex; CuA 2 ending at wing margin.

TERMINALIA ( Figs 8B–C , 9 ). Hypandrium is a distinct band that connects the gonocoxites, plate-like; gonocoxites are cylindrical, about the same length as gonostyli, gonostyli digitiform; gonocoxal apodeme fused; gonocoxal lobes without anterior projections, with 3–5 setae on each side, with gonocoxal spine; aedeagus digitiform with rounded apex, ending beyond the apex of the paramere, paramere digitiform, with rounded apex, about ¾ the length of the aedeagus; ejaculatory apodeme with anterior margin straight, shorter than the aedeagus; epandrium rectangular, about two times as wide as long; hypoproct V-shaped, and covered in small setulae, epiproct broader and shorter than hypoproct; surstyli conical narrowing towards the apex, curved ventrally, with two apical tenacula, tenacula with rounded apex.
