Cernotina longispina   sp. nov. Barcelos-Silva, Camargos & Pes

( Figs. 6 View FIGURE 6 A –B)

Cernotina   sp. 1, Barcelos-Silva et al. 2012, pp. 1279.

Etymology. The feminine noun longispina   refers to the long internal spine of the phallus, where longis (Latin) = long, spina (Latin) = spine.

Diagnosis. This species seems similar to C. attenuata Flint 1971   , but it can be easily distinguished by the shape of the ventromesal lobe of each preanal appendage: In C. longispina   sp. nov., there is a single projection in the apical portion while in C. attenuata   this region has two projections. Furthermore, the phallus in C. longispina   sp. nov. has an unique long spine, while in C. attenuata   there are two apical and four basal spines.

Description. Male. Length of each forewing 3.3–3.6 mm (n = 3). General color, in alcohol, yellowish brown; antennae pale yellow, tibia and tarsus of each foreleg with short dark brown setae, mid- and hind legs with golden setae.

Male genitalia: Sternum IX trapezoidal, anterior margin deeply excavated and posterior margin broad and broadly excavated in ventral view ( Fig. 6 View FIGURE 6 C). Tergum X membranous, tapering from base toward apex with shallow mesal notch apically, covered by setae on its dorsolateral surface in dorsal view ( Fig. 6 View FIGURE 6 B). Preanal appendages each composed of two lobes, in lateral view with dorsolateral lobe bifurcate mesally, dorsal branch longer than ventral, each branch with stout, black, apical spine, ventromesal lobe with broad base, tapering abruptly at middle, with two setae apically ( Fig. 6 View FIGURE 6 A). Inferior appendages, in lateral view, subrectangular, covered by fine setae; each with basodorsal lobe long, bearing row of stout setae on posteroventral surface in lateral view ( Fig. 6 View FIGURE 6 A), with many stout setae in ventral view; apicomesal lobe sclerotized, rounded apically with single fine and pointed projection basally (comma-like) in lateral view, with three stout setae in ventral view. Phallus tubular, base broader than apex, with a long internal spine (phallus not expanded) ( Fig. 6 View FIGURE 6 D).

Female: Unknown.

Holotype male: BRAZIL: Espírito Santo; Pinheiros, stream Água Limpa; 18 ° 22 '04.1"S, 40 °08' 23.8 "W; 21.v – 22.vi. 2010; J.M.C. Nascimento, J.O. Azeredo, and P. Barcelos-Silva; Malaise trap [alcohol]; (CZNC).

Paratypes: BRAZIL: Espírito Santo; Nova Venécia, Patrimônio do Bis; 18 ° 33 ' 27.5 "S, 40 ° 20 ' 6.5 "W; 25– 26.vii. 2012; K.A. Batista; Pennsylvania trap; 1 male [alcohol] (INPA); BRAZIL: Espírito Santo; Nova Venécia, Patrimônio do Bis; 18 ° 33 ' 27.5 "S 40 ° 20 ' 6.5 "W; 16–17.iv. 2012; K.A. Batista; Pennsylvania trap; 1 male [alcohol] (MZSP).

Biology. The specimens were collected in two different localities: on a narrow stream typical of the semideciduous Atlantic Forest, which has a sandy bottom with small rocks and leaves. And the other locality is a relatively large river without riparian vegetation and located near a city.
