Noctiliostrebla morena sp. n.

( Figs 1 A–E, G–I, 2A, C–D, 3A–B, D–G, 12, 17A)

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. This is the only species in which the setae of the cluster around spiracle III of the female are the same size as the setae on the longitudinal sideband. The male is similar to that of N. guerreroi sp. n., but can be distinguished from it by the setae on the ventral margin of the hypopygium, which are longer than the setae around the dorsal macrosetae of the hypopygium.

Description. Measurements (mm, n=20, 10 ♂♂, 10 ♀♀). HFL: ♂ 0.41 (0.38–0.45), ♀ 0,47 (0.45–0.51); SL: ♂ 0.51 (0.47–0.54), ♀ 0.56 (0.53–0.58); TL: ♂ 0.47 (0.43–0.49), ♀ 0.5 (0.46–0.54); WL: ♂ 0.29 (0.25–0.32), ♀ 0.29 (0.26–0.30); WW: ♂ 0.17 (0.15–0.19), ♀ 0.16 (0.15–0.18).

Thorax. Mesepimeron ( Fig. 1E ) with 1–2 setae on each side. Wings ( Fig. 1E, G ) with 0–3 setae on median vein. Metasternum ( Fig. 12B, E ) like in N. maai .

Female abdomen. Syntergite I+II ( Figs. 2A , 12A ) like in N. maai , except 26–37 setae on each plate of lateral lobe. Dorsal connexivum ( Fig. 12A ) resembling that of N. ecuadorensis sp. n., except as follows: cluster of setae around spiracle III with setae anterior to spiracle III as long as setae posterior to spiracle III, and longest setae 1/3 the length of longest setae on syntergite I+II; longitudinal sideband with setae as long as setae on cluster of setae around spiracle III and three times as long as setae on median dorsal connexivum; without setae near inner side of spiracle V; lateral pair of setae between each spiracle VI longer than longest setae on cluster of setae around spiracle III but not twice the length, and median pair of setae between each spiracle VI shorter than longest setae on longitudinal sideband of setae but longer than half their length. Tergite VII ( Figs. 2 C–D, 12A, C) like in N. guerreroi sp. n., except 4–8 setae on each plate. Sternite II ( Fig. 12B ) like in N. aitkeni . Sternite VII with 8–11 setae on each plate. Epiproct ( Figs. 2 C–D, 12A, C) like in N. maai .

Male abdomen. Syntergite I+II ( Fig. 3A ) like in N. maai , except 32–48 setae on each plate of lateral lobe. Ventral connexivum like in N. dubia . Sternite II ( Fig. 12E ) like in N. maai . Hypopygium ( Figs. 3 A–B, E–F, 12D–E) with 1–2 setae on ventral margin longer than setae around the dorsal macrosetae of hypopygium but not twice the length, and shorter than dorsal macrosetae of hypopygium; sternite VI like in N. aitkeni . Genitalia ( Figs. 3B , D–F, 12F–H) similar to N. guerreroi sp. n.

Etymology. A noun in apposition, the specific epithet “ morena ” refers to the nickname of the city of Campo Grande, capital of the state of Mato Grosso do Sul, Brazil. The holotype and most paratypes are from the state of Mato Grosso do Sul.

Remarks. We examined part of the material studied by Dick & Gettinger (2005), Presley & Willig (2008) and Presley (2011, 2012). Some of these specimens were identified by us as N. morena sp. n., whereas others were identified as N. pantaneira sp. n. The individuals of N. morena sp. n. were included in the type series. No specimen from their material was confirmed as N. maai . Like N. dubia , N. maai has also been recorded from Bolivia (Dick et al. 2007), but the specimens collected in that country may in fact belong to N. morena sp. n., since N. maai only occurs in Central America and northern South America.
