Diagnosis. Large (19.0– 20.3 mm). Dorsal body surface olive green, densely punctured (Fig. 64 A). Ventral surface dark yellow with transversal black bands on thorax and abdomen (Fig. 64 B). Antennae reddish brown (Fig. 64 A–B). Pronotum with brown punctures (Fig. 64 A); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.5 times wider than long); apex with black spot expanding slightly over the pronotal disc in dorsal view and restricted to the angles in ventral view; bent backward (Fig. 64 A–B). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria (Fig. 64 A). Coria with all veins concolorous with the surrounding surface (Fig. 64 A). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot (Fig. 64 A), spots not extending ventrally (Fig. 64 B). Posterolateral angles of connexivum with apices black (Fig. 64 A). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite (Fig. 64 B). Proepisternum with dark band (Fig. 64 B). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 64 B). Metasternal process (Fig. 31 G) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation slightly excavated receiving fourth and a small part of the third rostral segment. Legs with tibiae and tarsi reddish, remaining yellow to dark yellow (Fig. 64 B). Abdomen with spine of segment III rounded (Fig. 31 G). Intersegmental areas covered by solid black bands with well-defined margins, not reaching lateral margin (Fig. 64 B). Pseudosutures light brown with well-defined margins (Fig. 64 B). Median longitudinal brown band incomplete (Fig. 64 B). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX, almost reaching the level of apices of laterotergites VIII (Fig. 31 F). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface (Fig. 31 A–B). Posterolateral angles of the pygophore developed, projected laterally, apices with spots black (Fig. 31 A–B, D–E). Superior processes of the genital cup triangular, narrow, continuing ventrally in a crenulate, short and high carina (Fig. 31 B, D–E, crenulate carina barely visible). Parameres (Fig. 31 D–E) with black margins; anterior lobe rounded; dorsal lobe subtriangular, with very curved apex; posterior lobe rounded. Proctiger, posterior face subtriangular (Fig. 31 D–E). Surface ventral with dark spots medially and laterally (Fig. 31 C). Ventral rim with long setae but without a lateral tuft (Fig. 31 C); with expansions little developed, rounded, concolorous with the surrounding surface (Fig. 31 C). Female genitalia, valvifers VIII subrectangular, with dark punctures; sutural margins contiguous brown and not divergent; posterior margin in open U-shaped excavation, brown and slightly arched. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII (Fig. 31 F).
