Treatment

Tafalisca paranaensis de Mello & Dias, n. sp..

( Figs. 1–4; Table I)

Etymology: Species name allusive to the Paraná State, Brazil.

Material examined: Holotype male, Brazil, PR, Parque Nacional do Iguaçu, Trilha do Poço Preto, Foz do Iguaçu. 20-30.i.2008, Dias, P.G.B.S & de Mello, F.A.G. leg.; 2 female paratypes, same collectors and same locality

Repositories: Holotype and allotype [ MZSP]; 2 females paratypes [ UBTU].

Diagnosis. T. paranaensis , n. sp. differs T. paulista Rehn, 1918 , in the following characters: relatively smaller size; cephalic and caudal margins of the pronotum lightly curved; shorter tegmina, reaching the half of abdomen (covering the entire abdomen in T. paulista ); fore tibia with 5 spurs on inner face and 4 on outer ( T. paulista presents 5 on both faces); membranous area of pseudepiphallus dorsum with almost straight postlateral angles; pseudepiphallic parameres robust, like an ax. The figure 5 shows the differences between male genitalia of T. paranaensis , n. sp. and T. paulista .

Description: Male: size rather large and robust ( Figs. 1, 2 View FIGURE 2 A). Top of head obliquous in lateral view and rounded in frontal view; occiput border with two triangular pale spots; occiput and vertex dark brown; Black eyes, with a small unpigmented area on superointernal margin ( Fig. 2 View FIGURE 2 C); antennal scape whitish yelow, with brown basis; lateral ocelli small, close of antennal scape; median ocellus larger than lateral ones, located between the antennal scapes; frons, gena and clypeus pale light brown; labrum whitish yellow; maxillary palpi pale light brown, the fifth joint rounded, arcuate, lightly yellow than the others ( Figs. 2 View FIGURE 2 D, 3E); the fourth joint longer than fifth. Disc of pronotum velvety, dark brown above reddish brown background ( Figs. 1, 2 View FIGURE 2 B); cephalic margin darker, velvety, slightly concave ( Fig. 2 View FIGURE 2 B); caudal margin almost straight; lateral lobes with rounded borders, as colored as the disc. Legs I and II whitish yellow with a thin dark stripe on outer and inner femur surface ( Fig. 1); tibiae and femurs I and II same colored with proximal area darkened mainly on ventral face ( Fig. 1); 3 spurs on tibia I ventrocaudal extreme and 4 on tibia II; hind femur whitish yellow with a longitudinal contrasting dark stripe and dark brown narrow bands positioned over this stripe; apical extreme dark brown ( Figs. 1, 2 View FIGURE 2 I); tibia III as long as femur, dark brown with a yellow spot on anterior extremity; dorsal spurs: five large spurs without apical bristles on inner face intercalated by several strong spines and 4 smaller spurs on outer face, equipped with a small tuft of apical bristles ( Fig. 2 View FIGURE 2 J), the space between these spurs is intercalated by spines; apical spurs: the middle one is largest on both sides; basitarsus lighter than tibia, the others as colored as the tibia; basitarsus armed with 3 dorsal spines on outer face, 2 on inner face and one pair of ventro-apical spurs. Well developed tegmina, reaching the fifht abdominal tergite ( Figs. 1, 2 View FIGURE 2 A); stridulatory vein or specialized areas for sound communication, such as harp and mirror, absent; dorsal field with 11-12 obliquous veins, lateral field with. 7 veins; hind wings white and delicate, as long as the tegmina; metanotal structure well developed ( Fig. 2 View FIGURE 2 K). Abdomen glabrous, dorsally brownish, darkening from the last tergites, laterally light brown, also darkening towards the terminalia ( Figs. 1, 2 View FIGURE 2 A); sternites light brown, with a pair of longitudinal dark stripes in the last four sternites; supra-anal plate dark brown, the anterior margin concave and the posterior trapezoidal, pilose, with central smooth spots as in figures 2E, 3B; subgenital plate light brown with a darker spot in post-central zone ( Figs. 2 View FIGURE 2 G; 3D). Phallic complex: ( Fig. 4 View FIGURE 4 A-C) main lobe of pseudepiphallus with a “V” like posterior invagination, its dorsum with a membranous area with almost straight post-lateral angles; pseudepiphallic parameres like an ax; well developed rami; well developed ectophallic apodemes, parallel.

Female: general appearance bigger and stronger with same colour as male. Pronotum with caudal margin more distinctly convex; tegmina and fore wings extending beyond the fifth abdominal tergite. Supra-anal plate velvety, dark, with smooth spots ( Figs. 2 View FIGURE 2 F, 3A); subgenital plate yellowish with medium brown spots ( Figs. 2 View FIGURE 2 H, 3C). Ovipositor heavy, depressed, curved, reddish brown, figured with darked lateral bands, the apical borders lightly serrated ( Figs. 2 View FIGURE 2 L, M, N).

Tafalisca paulista Rehn, 1918 phallic complex. Posterior invagination of the main lobe of pseudepiphallus smaller than T paranaensis n. sp., with the apex straight and not curveted; membranous area of dorsum with a “U” like post-lateral angles; pseudepiphallic parameres similar to T. paranaensis n. sp. but less robust with thin apex; endophallic sclerite central, straight; well developed rami ( Fig. 5 View FIGURE 5 B, D, F).
