( 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.

Disc of pronotum velvety, dark brown above reddish brown background ( Figs. 1 , 2 B); cephalic margin darker, velvety, slightly concave ( Fig. 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 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 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 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 K). Abdomen glabrous, dorsally brownish, darkening from the last tergites, laterally light brown, also darkening towards the terminalia ( Figs. 1 , 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 G; 3D). Phallic complex: ( Fig. 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 : A—Supra-anal plate; C—Subgenital plate 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 F, 3A); subgenital plate yellowish with medium brown spots ( Figs. 2 H, 3C). Ovipositor heavy, depressed, curved, reddish brown, figured with darked lateral bands, the apical borders lightly serrated ( Figs. 2 L, M, N). FIGURE 4.
