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) like in  N. maai. Female abdomen. Syntergite I+II ( Fig. 8A) like in  N. maai, except 25–32 setae on each plate of lateral lobe. Dorsal connexivum ( Fig. 8A) 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) 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) like in  N. aitkeni, except posterior margin straight or slightly emarginate. Sternite VII with 8–10 setae on each plate. Epiproct ( Fig. 8A, C) 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) like in female. Hypopygium ( Fig. 8D–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. 8F–H) similar to  N. maai.   Distribution. Ecuador( Fig. 16A).     Typelocality. Ecuador, Sucumbios, Zábalo.   Host.  Noctilio albiventris.   Type material.  HOLOTYPE ♀: Ecuador: “ HOLOTYPE ♀/  Noctiliostrebla ecuadorensis/ Alcantara, Nihei & Graciolli”, “FMNH / Host.  N. albiventrisDesmarest/ ♂♂, ♀♀/ Ecuador, Sucumbios: Zabalo; Criollofamily’s property / 0°19’5.16”S, 75°45’58.32”W/  11.iii.2004/ J.S.
