Diagnosis. Juga stronglysinuous, continuous before tylus, with a quarter of the head length. Anterolateral margins of pronotum with one to eight acute teeth. Legs with black punctures. Spiracles placed onwhite calli. Pygophore ogival. Ventral rim processes long, about one third the length of the pygophore, with sutural margins convergent, well visible in profile.

Posterolateral margins of pygophore oblique, moderately excavated. Vesica long, less curved, with ventral opening. Laterotergites 8 with apex margin black.

Redescription. Generalcolor greenish-yellow, sometimes yellowish-brown to dark brown. Black punctures more concentrated on apex of juga, the remaining punctures concolorous with the dorsal surface of head. Lateral margins of juga, at apical third, outlined in black. Antenniferous tubercleswith black dots dorsally. More concentrated black punctures on basal third of pronotum, including humeral angles, and apical third of scutellum. A black line on posterior surface of humeral angles, extending until mid of posterior margin. Propleurum with a black line. Legs brown or greenish, with black punctures. Spines at apices of femur apically black. Spiracles concolorouswith the body surface, placed on white calli; trichobothria tubercles concolorous with the body.

Ovate and elongate ( Fig. 6 ). Head with frons and vertex flat. Juga projected anteriorly, juga measuring more than half the length of buccula in lateral view. Juga concave at base and slightly reflected at apical third. Ocelli placed on tubercles.

Comments. Juga are longer and wider than in remaining species of Thoreyella . The anterolateral marginsof pronotum with one to eight acute teeth and the black punctures on legs are autapomorphies to T. brasiliensis . Spiracles elevated by calli is shared with T. maracaja sp. nov., however the position of the spiracles on calli are distinct: in T. brasiliensis the spiracles are on the center of the calli, and in T. maracaja sp. nov. the spiracles are laterad. Also, the angle formed by the lobes of the parameres is distinct of the remaining species.
