description: Noctiliostrebla pantaneira sp. n.   
(Figs 2B, 13, 17B)  
 Noctiliostrebla maai: Dick & Gettinger (2005: 1020; part, survey, misidentification); Presley & Willig (2008: 80; tab. 2; part, misidentification); Presley (2011: 835; tab. 1; part, misidentification); Presley (2012: 5–6; tabs 1–2; part, misidentification).   
 Diagnosis. The pattern of setae on the connexivum of the female is very similar to that found in N. dubia, but it is mainly differentiated by the few setae in the middle of the bare areas on the median dorsal connexivum. The female sternite II is weakly emarginate compared to the shape observed in N. dubia and N. traubi. The male is easily recognized by the set of macrosetae anterior to sternite VI, and sternite II weakly emarginate.   
 Description. Measurements (mm, n=20, 10 ♂♂, 10 ♀♀). HFL: ♂ 0.45 (0.43–0.47), ♀ 0.52 (0.51–0.55); SL: ♂ 0.51 (0.49–0.53), ♀ 0.56 (0.55–0.58); TL: ♂ 0.49 (0.47–0.51), ♀ 0.52 (0.51–0.55); WL: ♂ 0.29 (0.27–0.31), ♀ 0.30 (0.28–0.33); WW: ♂ 0.17 (0.15–0.18), ♀ 0.18 (0.17–0.20).   
 Thorax. Mesepimeron with 1–2 setae on each side. Wing with 1–3 setae on median vein. Metasternum (Fig. 13B, E) like in N. traubi.   
 Female abdomen. Syntergite I+II (Fig. 13A) like in N. maai, except 35–56 setae on each plate of lateral lobe, and inner lateral margin moderately inclined. Dorsal connexivum (Fig. 13A) like in N. dubia, except as follows: with few short setae at middle of bare areas; row posterior to spiracle VI with one pair of setae in the middle as long as setae on cluster of setae around spiracle III. Lateral connexivum with free cluster of minute setae below spiracle III. Tergite VII (Fig. 13A, C) like in N. dubia, except 4–7 setae on each plate. Sternite II (Fig. 2B, 13B) with posterior margin weakly emarginate, and longest lateral setae twice as long as shortest median setae; discal setae not in row. Sternite VII (Fig. 2B) subtriangular and longer than wide; 8–13 setae on each plate. Epiproct (Fig. 13A, C) like in N. dubia.   
 Male abdomen. Syntergite I+II like in N. dubia, except 37–71 setae on each plate of lateral lobe. Ventral connexivum with segmental setae longer and thicker than other ventral setae but not twice the length, easily distinguishable. Sternite II (Fig. 13E) with posterior margin weakly emarginate, and longest lateral setae longer than shortest median setae but not twice the length. Hypopygium (Fig. 13 D–E) with ventral setae like in N. dubia; sternite VI straight or slightly curved, narrower and longer than half length of cercus; cluster of macrosetae anterior of sternite VI, 1–3 macrosetae longer than dorsal macrosetae of hypopygium but not twice the length. Genitalia (Fig. 13 F–H) like in N. guerreroi sp. n., except gonopod wider than in N. guerreroi sp. n., and dorsal margin of aedeagus similar to that of N. falsispina sp. n.

 Etymology. A noun in apposition, the specific epithet “ pantaneira ” refers to the traditional inhabitants of the Pantanal region, where the holotype and most of the paratypes are from.   
 Remarks. In his comments about N. dubia, Wenzel (1976) mentioned two females that have many features in common with N. pantaneira sp. n. However, the females he examined were from the state of Amazonas, Brazil, and do not match the geographical records of N. pantaneira sp. n. Some of the specimens studied by Dick & Gettinger (2005), Presley & Willig (2008) and Presley (2011, 2012) were identified by us as N. pantaneira sp. n. and were included in the type series. Many specimens of N. pantaneira sp. n. were collected on the same host individuals as N. morena sp. n.
