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.

Wing length: 1.70 (1.80–1.50), wing width: 0.79 (0.80–0.72); head length: 0.40 (0.40), head width: 0.35 (0.35); antennal segments: scape: 0.10 (0.11–0.08), pedicel: 0.06 (0.06–0.05), flagellomeres 1–7: 0.1 (0.11–0.10); palpal segment 1: 0.05 (0.5), palpal segment 2: 0.07 (0.07), palpal segment 3: 0.07 (0.07), palpal segment 4: 0.07 (0.07).

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

; 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.

DNA barcodes

Eleven specimens were successfully sequenced ZFMK-TIS-2629871, ZFMK-TIS-2629873, ZFMK- TIS-2636933, ZFMK-TIS-2636988, ZFMK-TIS-2637088, ZFMK-TIS-2637106, ZFMK-TIS-2637153, ZFMK-TIS-2637157, ZFMK-TIS-2637170, ZFMK-TIS-2637174, and ZFMK-TIS-2637178. The maximum intraspecific uncorrected pairwise distance for COI sequences was 0.46% or 2 bp.
