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.

Noctiliostrebla falsispina sp. n. , ♀ paratype (Brazil, Mato Grosso do Sul, Fazenda Querência, MZSP) and holotype ♂ (MZSP) (photographs in Figs 10D–E taken before dissection of genitalia). A. Female abdomen in dorsal view. B. Detail of posterior portion of female thorax and abdomen in ventral view, showing metasternal lobe and sternite II. C. Female tergite VII (with setae insertions) and epiproct in dorsal view. D. Detail of male abdomen in ventrolateral view, showing hypopygium. E. Detail of posterior portion of male thorax and abdomen in ventral view, showing metasternal lobe, sternite II and hypopygium. F. Male genitalia in lateral view. G. Asymmetrical distal portion of gonopods in lateral view. H. Distal portion of aedeagus in lateral view. 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.
