Total length: 19.0–20.3; head length: 1.9–2.0; head width: 3.4–3.5; pronotum length: 3.9–4.1; pronotum width: 12.5–13.6; scutellum length: 8.8–9.3; scutellum width: 6.5–7.0; abdominal width: 10.7– 11.8; length antennomeres: I: 1.0; II: 1.4–1.5; III: 1.8–2.0; IV: 3.8–4.0; V: 4.0–4.3.

Diagnosis. Large (19.0– 20.3 mm). Dorsal body surface olive green, densely punctured ( Fig. 64 A View FIGURE 64 ). Ventral surface dark yellow with transversal black bands on thorax and abdomen ( Fig. 64 B View FIGURE 64 ). Antennae reddish brown ( Fig. 64 A–B View FIGURE 64 ). Pronotum with brown punctures ( Fig. 64 A View FIGURE 64 ); 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 View FIGURE 64 ). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 64 A View FIGURE 64 ). Coria with all veins concolorous with the surrounding surface ( Fig. 64 A View FIGURE 64 ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 64 A View FIGURE 64 ), spots not extending ventrally ( Fig. 64 B View FIGURE 64 ). Posterolateral angles of connexivum with apices black ( Fig. 64 A View FIGURE 64 ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 64 B View FIGURE 64 ). Proepisternum with dark band ( Fig. 64 B View FIGURE 64 ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 64 B View FIGURE 64 ). Metasternal process ( Fig. 31 G View FIGURE 31 ) 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 View FIGURE 64 ). Abdomen with spine of segment III rounded ( Fig. 31 G View FIGURE 31 ). Intersegmental areas covered by solid black bands with well-defined margins, not reaching lateral margin ( Fig. 64 B View FIGURE 64 ). Pseudosutures light brown with well-defined margins ( Fig. 64 B View FIGURE 64 ). Median longitudinal brown band incomplete ( Fig. 64 B View FIGURE 64 ). 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 View FIGURE 31 ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 31 A–B View FIGURE 31 ). Posterolateral angles of the pygophore developed, projected laterally, apices with spots black ( Fig. 31 A–B, D–E View FIGURE 31 ). Superior processes of the genital cup triangular, narrow, continuing ventrally in a crenulate, short and high carina ( Fig. 31 B, D–E View FIGURE 31 , crenulate carina barely visible). Parameres ( Fig. 31 D–E View FIGURE 31 ) with black margins; anterior lobe rounded; dorsal lobe subtriangular, with very curved apex; posterior lobe rounded. Proctiger, posterior face subtriangular ( Fig. 31 D–E View FIGURE 31 ). Surface ventral with dark spots medially and laterally ( Fig. 31 C View FIGURE 31 ). Ventral rim with long setae but without a lateral tuft ( Fig. 31 C View FIGURE 31 ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 31 C View FIGURE 31 ). 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 View FIGURE 31 ).
