Diagnosis. Noctiliostrebla lamasi sp. n. resembles N. aitkeni and N. caissara sp. n. The setae on the longitudinal sideband of the female abdomen are as short as those on the median dorsal connexivum, and the setae composing the cluster of setae around spiracle III are not as long as in N. aitkeni. Tergite VII resembles that of N. caissara sp. n., but it is not three times as long the epiproct and its inner lateral margin is more than twice as long as the lateral margin of the epiproct. The male is very similar to that of N. aitkeni, but can be distinguished from it by sternite VI, the apical margin of which is wider than the cercus.

Description. Measurements (mm, n=20, 10 ♂♂, 10 ♀♀). HFL: ♂ 0.48 (0.45–0.54), ♀ 0.55 (0.52–0.56); SL: ♂ 0.55 (0.53–0.58), ♀ 0.60 (0.56–0.62); TL: ♂ 0.49 (0.41–0.53), ♀ 0.51 (0.45–0.54); WL: ♂ 0.31 (0.29–0.34), ♀ 0.32 (0.27–0.37); WW: ♂ 0.17 (0.16–0.19), ♀ 0.18 (0.15–0.21).

Thorax. Mesepimeron with 1–2 setae on each side. Wing with 0–3 setae on median vein. Metasternum (Fig. 11B, E) like in N. maai.

Female abdomen. Syntergite I+II (Fig. 11A) like in N. maai, except 19–31 setae on each plate of lateral lobe. Dorsal connexivum (Fig. 11A) like in N. aitkeni, except as follows: 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 less than half as long as longest setae on syntergite I+II; longitudinal sideband of setae with longest setae 1/2–1/3 the length of longest setae on cluster of setae around spiracle III, and twice as thick as, but less than twice the length of setae on median dorsal connexivum; lateral pair of setae between each spiracle VI like in N. maai; median pair of setae between each spiracle VI like in N. traubi. Tergite VII (Fig. 11A, C) with a short lobe, and strongly inclined on posterior margin; more than twice but less than three times the length of epiproct, and wider but not twice as wide as epiproct; inner lateral margin at least twice as long as lateral margin of epiproct; 5–8 setae on each plate. Sternite II (Fig. 11B) like in N. aitkeni. Sternite VII with 8–11 setae on each plate. Epiproct (Fig. 11A, C) like in N. maai.

Male abdomen. Syntergite I+II like in N. maai, except 24–37 setae on each plate of lateral lobe. Ventral connexivum like in N. dubia. Sternite II (Fig. 11E) like in N. aitkeni. Hypopygium (Fig. 11 D–E) like in N. aitkeni, except sternite VI with apical margin wider than but not twice as wide as cercus. Genitalia (Fig. 11 F–H) similar to those of N. aitkeni.

Etymology. The specific epithet honors Dr. Carlos Einicker Lamas, curator of Diptera at Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil.

Remarks. Part of the material misidentified as N. aitkeni by Graciolli & Carvalho (2001) and Prevedello et al. (2005) from Londrina (Paraná, Brazil) was identified here as N. lamasi sp. n. Some misidentified specimens studied by Dick & Gettinger (2005), Presley & Willig (2008) and Presley (2007, 2011, 2012) were also identified as N. lamasi sp. n. These specimens were included in the type series. Autino & Claps (2000) and Autino et al. (2009) recorded the occurrence of N. aitkeni in Argentina; we have not examined their material, but the specimens may indeed belong to N. lamasi sp. n. in view of their area of occurrence.
