Etymology. The name refers to the Pataxo indian people who inhabit the region of Bahia State where the holotype was collected.
Type specimen. Holotype ♂, BRAZIL, Bahia State, Itamaraju, 17° 4' S, 39° 32' S, 61m, ii-1988, L.F. Rey & J. Bento leg, deposited in ABMM.
Description. Male holotype. Head. Labium yellow, labrum orange, genae greyish yellow, base of mandibles, anteclypeus, postclypeus brown, antefrons light brown, upper part of head anterior to median ocellus reddish brown, remainder metallic black; pale diagonal band extending from lateral ocellus to antennal base, antennifer, scape and pedicel of antenna reddish brown; rear of head black. Thorax. Prothorax with pronotum orange red with black transverse spot at anterior part of hind lobe, propleuron yellowish orange; pterothorax with middorsal carina and medial 0.50 of mesepisternum dark metallic green, remainder of mesepisternum, mesepimeron and metepisternum orange red, metepimeron yellowish white. Legs, femora and tibiae light brown, tarsi dark brown. Wings hyaline. Px in FW 8 in HW 9, R3 arising near Px 7 in FW, near Px 5 in HW. Anal vein separating from wing margin at CuP in both wings; pterostigma light brown surmounting one cell. Abdomen. S1–2 dorsally orange, laterally yellow; S3–5 dorsally reddish orange, laterally yellowish; S6 red with a distal brown ring.
Structural characters. Hind prothoracic lobe with slight median concavity delimitating two rounded prominences. Cercus much shorter than S10, longer than paraproct (Fig. 19) in medio-dorsal view (Fig. 39) with a robust tooth whose tip is visible in lateral view (Fig. 28) at about midlength; paraproct in lateral view (Fig. 19) obliquely truncate, in medio-dorsal view dorsally concave (Fig. 28). Penis (Fig. 11) with well developed terminal fold and inner folds; distal half of apical segment missing.
Dimensions. Abdomen 23.9, HW 16.6
Female. Unknown.
Remarks: T. pataxo keys to couplet 7 of Key M6 (Garrison, 2009) that includes T. bickorum and T. erythrina. It differs from T. erythrina by having the cercus in medio-dorsal view with a robust conical tooth (Fig. 28; this replaced by a vertical tooth in T. erythrina, RG Fig. 17 h) and by the paraproct in lateral view truncate (Fig. 19; acuminate in T. erythrina, RG Fig. 21 f). From T. bickorum it differs by the absence of an humeral black stripe present in T. bickorum (RG Fig. 4 e), by the hind prothoracic lobe with a median concavity delimitating two lateral prominences, (evenly rounded in T. bickorum) and by the cercus that is truncate, and bent postero-ventrally in T. pataxo (Fig. 19; cercus roundly pointed and directed posteriorly in T. bickorum, RG Fig. 20 h). The cercus in medio-dorsal view is more slender in T. bickorum (RG Fig. 16 g) than in T. pataxo (Fig. 28).
