Figs 1, 20–21

Diagnosis

Male

Eye bridge with four facet rows (Fig. 20A); wing 2.1 times as long as wide; ejaculatory apodeme oval, about the same length as the aedeagus (Figs 20B, 21); gonocoxal apodeme with spine-like anterior projection; surstyli with seven tenacula (Figs 20B, 21); aedeagus digitiform and evenly tapering towards apex, and ending before the apex of paramere (Fig. 21), paramere shaped as an inverted J (Fig. 21B). This species shares the same number of facet rows in the eye bridge as B. uncinatum, B. tritaleum, B. clavigum, B. amazonensis, and B. claviformosum, but it can be easily differentiated by the number of tenacula on the surstyli (seven in B. septenacula sp. nov., five in B. amazonensis and B. claviformosum, one in B. uncinatum, and four in B. tritaleum).

Female

Unknown.

Etymology

The specific name derives from the Latin words ʻ septem ʼ meaning seven, and ʻ tenaculum ʼ (plural ʻ tenacula ʼ), the so-called stiff flattened setae on the inner apical surface of the surstyli of many Psychodidae . The name makes reference to the number of tenacula present in the species. Specific name to be treated as name in apposition.

Holotype male

HEAD (Fig. 20A). 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, trapezoidal with upper and lower margins straight. Antennal scape about two times the length of the pedicel, almost 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 seven; ascoids rectangular and broad, about the same length, and about two times as wide as flagellomere carrying them. Palpal segments cylindrical, palpal segment 4 with pointed apex, palpal proportions: 1.0:1.5:1.5:1.5; 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 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 (Figs 20B, 21). Hypandrium is a distinct band that connects the gonocoxites, plate-like; gonocoxites about the same length as gonostyli, gonostyli slightly incurved, with rounded-blunt apex; aedeagus digitiform, evenly narrowing towards the apex, apex rounded, ending beyond the level of the paramere, paramere resembling an inverted ʻJʼ (Fig. 21), apex pointed; ejaculatory apodeme oval, about the same length as the aedeagus, anterior margin rounded; gonocoxal apodemes projected anteriorly and fused, resembling an inverted and wide ʻUʼ, spine of the gonocoxal lobes present; epandrium narrow, rectangular, about three times as wide long; hypoproct digitiform, shorter than epandrium and covered in small setulae, epiproct shorter than hypoproct; surstyli conical, slightly tapering towards the apex and curved ventrally, with seven apical tenacula, tenacula with rounded apex.
