Thoreyella taurus Jensen - Haarup, 1931

( Figs. 4 , 64 , Table I )

Thoreyella taurus Jensen -Haarup, 1931: 321 (descr.); Rolston 1984: 830– 831 (descr.); Rider 1994: 218 (citation); Grazia et. al. 1999: 109 (cat.); Bernardes et al. 2009: 2–4, 7, 8, 10–12, 14, 15, 17, 18, 20–22 (classification, distr., fig.).

Diagnosis. Head darker than rest of body. Pronotal disc uniform in color. Humeral angles red, directed anteroventrally. Corium obscuring connexival segments; hemelytra surpassing apex of abdomen. Spiracles black. Genital plates flat; gonocoxites 8 obovate, without cusp. Band uniting the laterotergites 8 ventrally two times the segment X width.

Redescription. General color yellowish-brown. Head darker than the body because the concentration of black punctures on its base. Antenniferous tubercles with black punctures on dorsal side. Humeralangles red, with blackpunctures and a black line on posterolateral margins. Scutellum uniform in color, with reddish-brown punctures on posterior half. Propleurum with two black macula. Sternum dark. Legs concolorous with thebody. Spines at apices of femur apically black. Abdomen ventrally without macula. Posterolateral angles of urosterniteswith black apex. Punctures concolorous with the body, abundant on abdominal surface, less frequent along mid line. Spiracles black.

Ovate. Head with frons and vertex swollen. Juga apically flat; medianmargins higher than tylusin profile. Ocelli placed on tubercles. Buccula sinuous, apical tooth acute, posterior lobe attainingthe prosternum and obscuring first rostral segment laterally. Antennal segments: I<II>III<IV<V. Humeral angles developed in robust spines, apex obtuse, slightly directed anteroventrally. Pronotum slightly swollen between cicatrices. Scutellum almost as long as wide, apex rounded. Corium obscuring connexivum, hemelytra surpassing abdomen. Spines at apices of femur acute, short, less than one third the femur width, forming an angle with more than 45º. Abdominal spine broken (holotype). Spiracles not placed on a callus. Urosternites median sutures faint. Trichobothria placed laterally to the spiracles line. Posterior margin of segment VII in female (holotype) obscuring gonocoxites 8.

Female genitalia ( Fig. 64 ). Laterotergites 8 concave at base, sutural margins swollen. Ventral band of laterotergites 8 twice larger than the Xsegment width. Gonocoxites 8 obovate without a cusp. Laterotergites 9 triangular, apex rounded slightly emarginated, lateral half slightly carinated, median half flat. Gonapophyses 8 medially constricted, rounded ineach side of the faint longitudinal median suture. Segment Xrectangular.

Comments. Thoreyella taurus shares with T. cornuta and T. paraiba sp. nov. the head darker than the body.
