Diagnosis. Specimens large (15.3–17.2 mm). Dorsal surface of the body green (Fig. 24 E). Ventral surface dark yellow to brown with transversal black lines on thorax and abdomen (Fig. 24 F). Antennae reddish brown (Fig. 24 E). Pronotum with punctures brown or concolorous with surface (Fig. 24 E); anterolateral margin and cicatrices with brown punctures (Fig. 24 E). Humeral angles short (1,25 times wider than long) (Fig. 24 E), apices concolorous with surface and not recurved (Fig. 24 E). Scutellum with punctures brown or concolorous with surface (Fig. 24 E); apex not reaching end of corium (Fig. 24 E). Corium with all veins concolorous with surface (Fig. 24 E). Posterolateral angles of connexivum with apices black (Fig. 24 E); connexival segments with concavities partially covered by circular black spots and separated by large yellow median spot (Fig. 24 E), dark spots extending ventrally, rounded (Fig. 24 F). Ventral surface. Thorax with black stripes (Fig. 24 F); dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 24 F). Evaporatorium concolorous with thorax (Fig. 24 F). Metasternal process (Fig. 3 G) with anterior apex straight and laterally well expanded, margin acuminated; anterior face broadly excavated; anterior bifurcation receiving fourth rostral segment. Legs with tibiae and tarsi darker than the rest (Fig. 24 F). Abdomen with spine of third segment acuminated (Fig. 3 G). Intersegmental areas black, not reaching ventral spots of connexivum (Fig. 24 F). Pseudosutures partially covered by superficial black stripe (Fig. 24 F). Median longitudinal black band incomplete (Fig. 24 F). Trichobotria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching level of apices of laterotergites IX in females (Fig. 3 F). Male genitalia, posterolateral angle of pygophore slightly developed (Fig. 3 A). Superior process of genital cup laminar, rectangular, thick; flattened and coarse in caudal view, continuing ventrally in a crenulated high carina without a distal projection (Fig. 3 A,B,E). Ventral rim setose with medial tuft (Fig. 3 C,D). Female genitalia, valvifers VIII with distal margin sinuous (Fig. 3 F). Laterotergites VIII with two small dark spots on outer lateral margins (Fig. 3 F).

Male genitalia (Fig. 3 A–E): Parameres with brown margin, anterior lobe small and rounded; dorsal lobe rounded and subrectangular, curved at apex; posterior lobe narrow and rounded (Fig. 3 D,E). Proctiger with subpentagonal posterior face (Fig. 3 D,E). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles (Fig. 3 B,C).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous, with brown band and divergent; distal margin brown and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 3 F).
