Diagnosis. Large (20.8–21.9 mm). Dorsal body surface dark green (54 E). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen (Fig. 54 F). Mandibular plates with black punctures along the anterior margin (Fig. 54 E). Antennae reddish brown (Fig. 54 E–F). Pronotum with black punctures (Fig. 54 E); anterior and anterolateral margins with black punctures. Humeral angles short (1.4 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; bent backward (Fig. 54 E–F). Scutellum with black punctures (Fig. 54 E); apex acute, excavated medially, not reaching the apex of coria (Fig. 54 E). Coria with all veins yellowish green (Fig. 54 E). Connexival segments black with three very small dark yellow calloused areas (Fig. 54 E); black spot barely extending ventrally (Fig. 54 F). Posterolateral angles of connexivum with black apices (Fig. 54 E). Ventral surface, thorax with black bands; dark band of propleura covering 2/3 of the width of the sclerite (Fig. 54 F). Proepisternum with dark band (Fig. 54 F). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 54 F). Metasternal process (Fig. 3 G) with anterior arms of anterior bifurcation straight and well expanded laterally at apex; anterior bifurcation slightly excavated receiving the fourth rostral segment. Legs brown (Fig. 54 F). Abdomen with spine of segment III acuminated (Figs. 3 G; 54 F). Intersegmental areas covered by narrow solid black bands with well-defined margins, not reaching the lateral spots (Fig. 54 F). Pseudosutures concolorous with the surrounding surface (Fig. 54 F, dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete (Fig. 54 F). Trichobothria both in line with spiracles. Posterolateral angles of segment VII slightly exceeding the level of the apices of laterotergites IX (Fig. 3 F, consider the angles to the left of the observer). Male genitalia, dorsal side of the pygophore with a medial smudged brown spot occupying 1/3 of the surface (Fig. 3 A–B). Posterolateral angles of the pygophore developed, projected laterally (Fig. 3 A–B); apices with black spot (Fig. 3 A–B). Superior processes of the genital cup thick, tapering, flattened distally and coarse in posterior view, continuing ventrally in a crenulate high carina, ending in a developed digitiform projection (Fig. 3 B, D–E). Parameres with black margin, fan-like; posterior lobe somewhat more developed than anterior lobe, dorsal lobe not curved laterally (Fig. 3 D–E); anterior face with carina. Proctiger, posterior face subtriangular (Fig. 3 D–E). Ventral rim setose, with medial tuft (Fig. 3 C), with expansions little developed, rounded and concolorous with the surrounding surface (Fig. 3 C–E). Ventral surface with black punctures, distributed in deep “V”; medially with longitudinal black spot (Fig. 3 C). Female genitalia, valvifers VIII with some median brown punctures, posterior margin straight and laterally angles; sutural margins contiguous, brown and slightly excavated distally in a small and shallow U-shaped concavity. Valvifers IX large, not carinated. Laterotergites VIII with dark outer lateral margins. Laterotergites IX with apices acuminate exceeding the mediotergite VIII (Figs. 3 F, 4 F).
