Diagnosis

Male Eye bridge with three facet rows ( Fig. 13A ); wing 1.9 times as long as wide; ejaculatory apodeme cylindrical and hour-glass-shaped, about the same length as the aedeagus ( Fig. 13B, D ); aedeagus digitiform, outcurved and evenly tapering towards apex ( Fig. 13B, D ); gonocoxal apodeme fused ( Fig. 13B, D ); surstyli with one tenaculum ( Fig. 13C ). This species shares the same number of apical tenacula in the surstyli 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. curvum sp. nov., four in B. uncinatum , and five in B. paulistensis ).

Female

Unknown.

Etymology

Specific name is derived from Latin ʻ curvus ʼ (neuter ʻcurvumʼ), making reference to the outcurved gonocoxites, as well as the curved aedeagus and paramere. Specific name to be treated as a noun in apposition.

Type material

Holotype

COLOMBIA – Magdalena • ♂; Sierra Nevada de Santa Marta, El Ramo ; alt. 2400 m; 10–24 Jun. 2000; I. Uribe leg.; Malaise trap; LACM, LACM-ENT-279396.

Description

MEASUREMENTS. In mm (n = 1). Wing length: 2.47, wing width: 1.28; head length: 0.50, head width: 0.60; antennal segments: scape: 0.10, pedicel: 0.06, flagellomeres 1–4: 0.11 (0.11–0.12); palpal segment 1: 0.04, palpal segment 2: 0.8, palpal segment 3: 0.07, palpal segment 4: 0.05.

Holotype male

HEAD ( Fig. 13A ). A little wider than long; eye bridge contiguous, with three 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, slightly broader than wide; 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 four; ascoids absent in examined material. Palpal segments cylindrical, palpal segment 4 with pointed apex, palpal proportions: 1.0:2.0:1.7:1.2; labium without strong sclerites; 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 1.9 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 same level as M 1+2 and joining R 4; fork of M 1+2 weak; R 5 ending at the wing apex; CuA 2 ending at wing margin.

TERMINALIA ( Fig. 13B–D ). Hypandrium is a distinct band that connects the gonocoxites, plate-like; gonocoxites cylindrical, shorter than gonostyli, gonostyli digitiform and outcurved, with rounded-blunt apex; aedeagus digitiform and outcurved, evenly narrowing towards the apex, apex pointed, ending at the level of the apex of the paramere, paramere digitiform and out curved, paramere evenly narrowing towards the apex, apex pointed; ejaculatory apodeme almost cylindrical, waisted and resembling a broad hour-glass shape, about the same length of the aedeagus; gonocoxal apodemes fused; epandrium like a narrow rectangle, about four times wider than long; hypoproct tongue-shaped, longer than epandrium and covered in small setulae, epiproct shorter than hypoproct; surstyli conical, evenly tapering towards the apex, with one apical tenaculum, tenaculum with rounded apex.
