Noctiliostrebla guerreroi sp. n.

( Figs 1F , 9 , 16B )

Noctiliostrebla maai: Graciolli & Bernard (2002: 79; survey records, misidentification) .

Diagnosis. The females of Noctiliostrebla guerreroi sp. n. and N. ecuadorensis sp. n. are similar, but in the second species the longest setae on the longitudinal sideband are three times as long as those on the median dorsal connexivum of N. guerreroi sp. n. The male of N. guerreroi sp. n. is very similar to those of N. aitkeni , N. lamasi sp. n. and N. moren a sp. n., and is difficult to distinguish from them. However, the setae on the ventral margin of the hypopygium of N. guerreroi are not longer than the setae around the dorsal macrosetae of the hypopygium as in N. moren a sp. n., and the gonopods are not subacuminate at apex as in N. aitkeni , N. lamasi sp. n.

Description. Measurements (mm, n=7, 2 ♂♂, 5 ♀♀). HFL: ♂ 0.4 (0.39–0.41), ♀ 0.49 (0.45–0.52); SL: ♂ 0.5 (0.49–0.51), ♀ 0.55 (0.53–0.57); TL: ♂ 0.43 (0.43–0.44), ♀ 0.49 (0.48–0.51); WL: ♂ 0.26 (0.25–0.26), ♀ 0.28 (0.26–0.31); WW: ♂ 0.14 (0.13–0.16), ♀ 0.16 (0.14–0.17).

Thorax. Mesepimeron with 1–2 setae on each side. Wing with 0–3 setae on median vein. Metasternum ( Figs 1F , 9B, E ) like in N. maai .

Female abdomen. Syntergite I+II ( Fig. 9A ) like in N. maai , except 23–35 setae on each plate of lateral lobe. Dorsal connexivum ( Fig. 9A ) resembling that of N. ecuadorensis sp. n., except as follows: longitudinal sideband with longest setae three times as long as setae on median dorsal connexivum; lateral pair of setae between each spiracle VI like in N. maai . Tergite VII ( Fig. 9A, C ) like in N. maai , except: twice as long as epiproct; inner lateral margin at most twice as long as lateral margin of epiproct; 3–5 setae on each plate. Sternite II ( Fig. 9B ) like in N. aitkeni . Sternite VII with 6–11 setae on each plate. Epiproct ( Fig. 9A, C ) like in N. maai .

Male abdomen. Syntergite I+II like in N. maai , except 31–43 setae on each plate of lateral lobe. Ventral connexivum like in N. maai . Sternite II ( Fig. 9E ) like in N. maai . Hypopygium ( Fig. 9 D–E) like in N. ecuadorensis sp. n., except as follows: setae on ventral margin like in N. dubia ; sternite VI with apical margin wider than half the width of cercus. Genitalia ( Fig. 9 F–H) like in N. maai , except as follows: gonopod with distance between distal setae and apex more than 1.5 times and less than twice distance between distal setae and dorsal margin.

Distribution. Brazil (Amazonas, Mato Grosso, Pará) ( Fig. 16B ).

Type locality. Brazil, Pará , Itaituba .

Host. Noctilio albiventris .

Type material. HOLOTYPE ♀: Brazil: “ HOLOTYPE ♀ / Noctiliostrebla guerreroi / Alcantara, Nihei & Graciolli”, “46.730-A.10.27 / Noctiliostre- / bla sp. / 2 ♂ 2 ♀ / Guim. det.”, “ Noctilio a. al- / biventris-Itai- / tuba, PA, K, 57 / Trans., S.A.

Marciente & J.F.T. Andes Jr. leg., on N. albiventris ( MZSP) ; 1 ♂, same data as previous except 4°40’52.901”S, 61°21’50.763”W, 25.viii.2013 ( MZSP) ; 3 ♀♀, Mato Grosso, Paranaíta , 09°27’11.12”S, 56°30’37.11”W, 1.xi.2009, L.F.A.C. Carvalho leg., on N. albiventris ( ZUFMS) ; 2 ♂♂, 1 ♀, same data as holotype ( MZSP) ; 3 ♂♂, 2 ♀♀, Pará, Santarém, Vila Alter do Chão , 31.vi.2000, Bernard leg., on N. albiventris ( DZUP) .

Etymology. The specific epithet is in honor of Dr. Ricardo Guerrero, taxonomist of bat flies at Universidad Central de Venezuela, Caracas, Venezuela.

Remarks. The specimens studied by Graciolli & Bernard (2002) and misidentified as N. maai are actually N. guerreroi sp. n. and were included in the type series.
