Noctiliostrebla ecuadorensis   sp. n.

( Figs 8 View FIGURE 8 , 16A View FIGURE 16 )

Diagnosis. The female is very similar to N. guerreroi   sp. n. (described below). The feature that distinguishes females of N. ecuadorensis   sp. n. and N. guerreroi   sp. n. is the length of the setae on the longitudinal sideband in relation to the length of the setae on the median dorsal connexivum. The male is very similar to that of N. maai   , but is easily identified through sternite VI, which is half as wide and longer than half the length of the cercus.

Description. Measurements (mm, n=10, 5 ♂♂, 5 ♀♀). HFL: ♂ 0.42 (0.40–0.43), ♀ 0.48 (0.46–0.51); SL: ♂ 0.51 (0.50–0.53), ♀ 0.55 (0.52–0.59); TL: ♂ 0.47 (0.44–0.49), ♀ 0.50 (0.48–0.53); WL: ♂ 0.26 (0.26–0.28), ♀ 0.28 (0.25–0.32); WW: ♂ 0.16 (0.16–0.18), ♀ 0.16 (0.15–0.17).

Thorax. Mesepimeron with 1–2 setae on each side. Wing with 0–2 setae on median vein. Metasternum ( Fig. 8B, E View FIGURE 8 ) like in N. maai   .

Female abdomen. Syntergite I+II ( Fig. 8A View FIGURE 8 ) like in N. maai   , except 25–32 setae on each plate of lateral lobe. Dorsal connexivum ( Fig. 8A View FIGURE 8 ) with a cluster of setae around spiracle III, setae anterior to spiracle III longer than but not twice the length of setae posterior to spiracle III, and longest setae half the length of longest setae on syntergite I+II; longitudinal sideband extending beyond outer lateral margin of spiracle and centered at spiracle, with 4–5 rows of setae, the longest setae half the length of longest setae on cluster of setae around spiracle III and twice as long as longest setae on median dorsal connexivum; 1–2 setae near inner side of spiracle V, longer than but not twice as long as longest setae on longitudinal sideband; lateral and median pairs of setae between each spiracle VI similar to those in N. traubi   . Tergite VII ( Fig. 8A, C View FIGURE 8 ) like in N. maai   , except inner lateral margin longer than lateral margin of epiproct but not twice the length; 5–6 setae on each plate. Sternite II ( Fig. 8B View FIGURE 8 ) like in N. aitkeni   , except posterior margin straight or slightly emarginate. Sternite VII with 8–10 setae on each plate. Epiproct ( Fig. 8A, C View FIGURE 8 ) like in N. maai   , except anteromedial setae shorter than posterior setae but longer than half their length.

Male abdomen. Syntergite I+II like N. maai   , except 29–34 setae on each plate of lateral lobe. Ventral connexivum like in N. maai   . Sternite II ( Fig. 8E View FIGURE 8 ) like in female. Hypopygium ( Fig. 8 View FIGURE 8 D–E) with setae on ventral margin like in N. dubia   ; sternite VI very thin, shorter than cercus but longer than half its length, apical margin half the width of cercus. Genitalia ( Fig. 8 View FIGURE 8 F–H) similar to N. maai   .

Distribution. Ecuador ( Fig. 16A View FIGURE 16 ).

Type locality. Ecuador, Sucumbios, Zábalo   .

Etymology. The specific epithet is a reference to Ecuador, the only country with records of the species so far.
