Etymology. Name allusive to the type-locality.

Diagnosis. Head darker than the rest of the body. Juga short with one third the length of buccula. Punctures of head black, distinctly darker than head surface ( Fig. 12 View Figs ). Pronotal disc strongly convex medially. Humeral angles in short spines directed laterad. Scutellum basal angles with reddish brown or dark brown punctures. Spine at apex of femur short. Process of the ventral rim of pygophore ( Fig. 14 View Figs ) with 2 + 2 teeth on posterior margin, the former tooth acute, obscuring the second. Parameres with a clear strip between the dark lobes of apical portion. Gonocoxites 8 obovate with a short cusp.

Description. General color yellowish-brown ( Fig. 2 View Figs ), punctures concolorous with body surface or dark brown, sometimes reddish-brown. Head dark brown, with dark punctures ( Fig. 12 View Figs ); tylus and median margins of juga lighter in color than front and vertex. Antenniferous tubercles with some black punctures and a castaneous stripe dorsally which extends along margins of juga. Humeral angles with dark punctures on posterolateral margins. Pronotal disc yellowish-brown on males; reddish-brown anterior to transverse callus and dark-brown after callus on females ( Fig. 2 View Figs ). Basal angles of scutellum with red or dark brown punctures. Propleura with two dark macula; mesopleura without macula. Sternum blackon females; castaneous on males. Legs darker than the venter. Spiracles with castaneous ring; trichobothria tubercles concolorous with the body surface.

Ovate. Head ( Fig. 12 View Figs ): juga short, measuring one third the length of buccula in lateral view; frons and vertex swollen; cicatrices adjacent to eyes, occupying almost half the length of eyes; ocelli directed anteriorly. Antennal segments: I<II~III<IV<V. Pronotal disc strongly sloping, medially convex; transverse callus sinuous, reaching humeral angles; longitudinal calloused line ending in a callus between cicatrices. Humeral angles in short acute spines dorsolaterally directed. Scutellum divided by apices of claval suture in two equally portions, basal half convex, basal angles slightly concave. Opening of odoriferous glands small; ostiolar ruganot reaching the middle of metapleura, curved to mesopleura; evaporative area reduced, not extendingalong ostiolar ruga. Spines at apices of femur acute, short, less than half the femur width, forming an angle with more than 45º but less than 90º. Abdominal spine short, thin, attaining metacoxae. Spiracles not placed on a callus. Posterior margin of segment VII in females with lateral thirds sinuous, the convex portion obscuring basal concavity of laterotergites 8.

Male genitalia ( Figs. 14 View Figs , 19 View Figs , 24, 29 View Figs ). Pygophore. Process of the ventral rim ( Fig. 14 View Figs , vrp) with 2 + 2 teeth on posterior margin, the former tooth triangular, acute, obscuring the second pair, with less than half the size of the former pair. Posterolateral angles ( Fig. 14 View Figs , pla) strongly angulate, concavity occupying almost half width of the ventral rim process. Sutural margins of ventral rim processes posteriorly parallel, anteriorly sinuous. Median extensions of ventral rim processes slightly extended in lateral view. Posterior margin of the infolding of ventral rim with a median sulcus in “V”, margins swollen ( Fig. 19 View Figs , ivr). Parameres with apical portion bilobate; lobes clearly separate by a non-pigmented stripe.

Female genitalia ( Fig. 62 View Figs ). Laterotergites 8 ( Fig. 62 View Figs , la8) concave at base and flat at apex, sutural margin swollen. Gonocoxites 8 ( Fig. 62 View Figs , gc8) obovate with a moderate cusp, similar to T. maracaja sp. nov. ( Fig. 65 View Figs ). Laterotergites 9 ( Fig. 62 View Figs , la9) slightly surpassing segment X, lateral half scarcely elevate, not forming a carina, median half flat; apex slightly emarginated, median margins slightly concave. Gonapophyses 8 ( Fig. 62 View Figs , g 8 View Figs ) with posteriormargin elevated at middle. Segment Xlonger than wide with transverse grooves.

Distribution. BRAZIL: Paraíba.

Material examined. Holotype male. BRAZIL. Paraíba: Soledade, Juazeirinho , 8.VII.1956, A. G.A. Silva col., Campos Seabra Collection ( MNRJ). Paratype Female. BRASIL. Paraíba: Soledade, Juazeirinho , 8.VII.1956, A. G. A. Silva col., Campos Seabra Collection ( UFRG) .

Comments. T. paraiba sp. nov. shares with T. cornuta the homoplastic character juga short with one third the length of buccula. Can be distinguished by the humeral angles less developed and directed laterad, shorter spine at apex of femur, and the presence of a median callus between cicatrices of pronotum.These speciesalso share, in females, the gonocoxites 8 with a small cusp, and in males, the greater and more acute triangular teeth of the ventral rim of pygophore processes.
