 Noctiliostrebla traubi Wenzel in Wenzel et al., 1966: 565 –566 (figs 106a–b, 107b, 107d). Holotype ♂ (FMNH). Type locality: Panama, Canal Zone, Fort Sherman. Host: Noctilio leporinus [as N. leporinus mexicanus Goldman]. Other references: Wenzel (1970: 11–12; catalog); Wenzel (1976: 111, 114–115; figs 44c–d, 45a, c; comments and list of examined material); Guerrero (1995: 148; diagnosis); Guerrero (1997: 11; catalog); ter Hofstede et al.

 Lepopteryx megastigma: Speiser (1900a: 54–55; part, misidentification).   
 Diagnosis. The female of N. traubi is distinguished from females of other species by epiproct with anterolateral pair of setae thicker than posterior setae, anteromedial pair of setae lacking, sternite II moderately emarginate and inner lateral margin of tergite VII shorter than lateral margin of epiproct. The male presents sternite II strongly arched and with median setae on posterior margin forming a pseudoctenidium, gonopod strongly curved before distal macroseta and with distal half strongly tapered.   
 Redescription. Measurements (mm; n = 20, 12 ♂♂, 8 ♀♀): HFL: ♂ 0.45 (0.43–0.46), ♀ 0.57 (0.54–0.59); ST: ♂ 0.49 (0.47–0.51), ♀ 0.57 (0.55–0.60); TL: ♂ 0.45 (0.43–0.47), ♀ 0.49 (0.48–0.52); WL: ♂ 0.28 (0.24–0.32), ♀ 0.3 (0.28–0.35); WW: ♂ 0.16 (0.15–0.17), ♀ 0.17 (0.15–0.20).   
Thorax. Mesepimeron with one seta on each side. Wing with 0–1 setae on median vein. Metasternum (Fig. 5B) with metasternal lobe moderately emarginate; distance between coxal condyle III and metasternal lobe apex three times as wide as width of metasternal lobe emargination.  
 Female abdomen. Syntergite I+II (Fig. 5A) with lateral lobe with 21–31 setae on each plate; inner lateral margin like in N. dubia, but slightly inclined, with setae throughout. Dorsal connexivum (Fig. 5A) with cluster of setae around spiracle III, with setae anterior to spiracle III at most twice as long as setae posterior to spiracle III, and longest setae half as long as longest setae on syntergite I+II; longitudinal sideband as in N. dubia. but with two rows of setae, setae 1\3 the length of the longest setae on cluster of setae around spiracle III, as long as and at most twice as thick as setae on median dorsal connexivum; lateral pair of setae between each spiracle VI shorter but more than half as long as longest setae on cluster of setae around spiracle III, and median pair of setae between each spiracle VI longer than longest setae on longitudinal sideband but not twice their length. Tergite VII (Fig. 5A, C) strongly inclined and with a conspicuous lobe on posterior margin; longer than epiproct but not twice its length; inner lateral margin shorter than lateral margin of epiproct; 4–6 setae on each plate. Sternite II (Fig. 5B) resembles that of N. dubia, but moderately emarginate on posterior margin. Sternite VII with 7–11 setae on each plate. Epiproct (Fig. 5A, C) like in N. dubia, except as follows: anteromedial pair of setae absent, anterolateral pair of setae half as long as posterior setae.   
 Male abdomen. Syntergite I+II with 27–43 setae on each plate of lateral lobe; inner lateral margin similar to that of female. Ventral connexivum like in N. dubia. Sternite II (Fig. 5D) with posterior margin strongly arched; median setae on posterior margin forming a pseudoctenidium, at most twice as long as smallest lateral setae on posterior margin. Hypopygium (Fig. 5E) with setae on ventral margin like in N. dubia; sternite VI twice as long as cercus, strongly elongated and inclined on posterior margin. Genitalia (Fig. 5 F–H) with gonopod strongly curved before distal macroseta (angle of 90°), distal half strongly tapered and acuminate at apex, and distance between distal setae and apex of gonopod less than or equal to 1.5 times distance between distal setae and dorsal margin of gonopod; aedeagus similar to that of N. dubia.

 Remarks. Wenzel et al. (1966) mentioned that some specimens received from Cuba, and which are similar to N. traubi, could represent a new species. Unfortunately, we were not able to examine specimens from this region to confirm or to refute that.
