description: Noctiliostrebla falsispina sp. n.   
(Figs 10, 16C)  
 Noctiliostrebla dubia: Dick & Gettinger (2005: 1019; part, survey, misidentification); Presley (2007: 409–417; part, hostparasite relationship, misidentification); Presley (2011: 835; tab. 1; part, misidentification); Presley (2012: 5–6; tabs 1–2; part, misidentification).   
 Noctiliostrebla aitkeni: Graciolli & Carvalho (2001: 929–930; part, catalog, misidentification); Moura et al. (2003: 811–815; part, host-parasite relationship, misidentification); Prevedello et al. (2005: 197, 202, 209; tab. 1; part, survey records, richness matrix, misidentification).   
 Diagnosis. Noctiliostrebla falsispina sp. n. is very similar to N. dubia and can be distinguished from it only by the presence of a thorn-like membranous projection on the dorsal margin of the aedeagus.   
 Description. Measurements (mm, n=19, 10 ♂♂, 9 ♀♀). HFL: ♂ 0.49 (0.45–0.52), ♀ 0.56 (0.55–0.58); SL: ♂ 0.49 (0.46–0.52), ♀ 0.51 (0.44–0.54); TL: ♂ 0.47 (0.45–0.51), ♀ 0.49 (0.47–0.51); WL: ♂ 0.32 (0.28–0.39), ♀ 0.31 (0.29–0.35); WW: ♂ 0.19 (0.16–0.22), ♀ 0.19 (0.17–0.20).   
 Thorax. Similar to N. dubia, except in the following structures: scutellum of female with setae half as long as setae on scutum; mesepimeron with 1–2 setae on each side.   
 Female abdomen (Fig. 10 A–C). Similar to N. dubia, except syntergite I+II (Fig. 10A) with 20–36 setae on each plate of lateral lobe.   
 Male abdomen (Fig. 10 D–H). Similar to N. dubia, except in the following structures: syntergite I+II with 32– 44 setae on each plate of lateral lobe. Genitalia (Fig. 10 F–H) with dorsal margin of aedeagus with a thorn-like membranous projection and without a sclerotized thorn.   
 Distribution. Brazil (Mato Grosso do Sul, Paraná), Paraguay (Fig. 16C).   
 Type locality. Brazil, Mato Grosso do Sul, Aquidauana, Fazenda Querência.   
 Host. Noctilio leporinus.   
 Type material. HOLOTYPE ♂: Brazil: “ HOLOTYPE ♂ / Noctiliostrebla falsispina / Alcantara, Nihei & Graciolli”, “MZSP / Host. N. leporinus Linnaeus / Brazil, state of Mato Grosso do Sul, Aquidauana, Fazenda Querência / 19 o 23’20.9”S, 55 o 33’28”W / 13.iii.2013 / L.F.A.C. Carvalho leg. / ∆ 11 N. dubia” on slide (MZSP). PARATYPES (14 ♂♂, 6 ♀♀): Brazil: 1 ♂, 1 ♀, same data as holotype (MZSP); 1 ♂, 2 ♀♀, same data as holotype (ZUFMS); 2 ♂♂, 1 ♀, state of Mato Grosso do Sul, Corumbá, riparian forest, 18.v.1999, Missirian leg., on N. leporinus (DZUP); 3 ♂♂, state of Paraná, Londrina, igapó vegetation, 22.xi., Lima leg., on N. leporinus (DZUP). Paraguay: 1 ♂, Concepción, Estancía Cerrito, 120m, 23°15.64’S, 57°30.32’W, 25.xi.1995, R. D. Owen & M.R. Willig leg., on N. leporinus (FMNH); 3 ♂♂, 1 ♀, same data as previous except 23°13.35’S, 57°31.61’W, 29.xi.1995, (FMNH); 3 ♂♂, 1 ♀, Presidente Hayes, Estancía La Victoria, 120m, 23°39.03’S, 58°34.79’W, 27.vii.1995, R. D. Owen & M.R. Willig leg., on N. leporinus (FMNH).   
 Etymology. The specific epithet is formed of the Latin words “ falsus ” and “ spina ”, meaning false thorn, in references to the thorn-like membranous projection on the dorsal margin of the aedeagus.   
 Remarks. We identified specimens of N. falsispina sp. n., along with specimens of N. lamasi sp. n., in the material misidentified as N. dubia and N. aitkeni by Graciolli & Carvalho (2001), Prevedello et al. (2005), Dick & Gettinger (2005) and Presley (2007, 2011, 2012). These specimens were included in the type series.
