Material examined. Holotype male. BRAZIL, Amazonas: Ceplac, Rod. AM-01 km 30, 7-V-1970, I. S. Gorayeb (INPA).

Measurements (n= 1). Total length: 19.3; head length: 1.8; head width: 3.8; pronotum length: 4.3; pronotum width: 14.0; scutellum length: 8.8; scutellum width: 7.0; abdominal width: 10.5; length antennomeres: I: 1.0; II: 2.0; III: 2.0; IV: 4.5.

Diagnosis. Large (19.3 mm). Dorsal body surface olive green, densely punctured (Fig. 61 A). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen (Fig. 61 B). Head with concolorous with the surrounding surface to brown punctures. Antennae reddish brown (Fig. 61 A). Pronotum with brown punctures (Fig. 61 A); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.2 times wider than long); apex with dark brown restricted to the angles in dorsal view; slightly bent backward (Fig. 61 A–B). Scutellum with brown to black punctures; posterior part excavated medially; apex not reaching the end of coria (Fig. 61 A). Coria with all veins concolorous with the surrounding surface (Fig. 61 A). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot (Fig. 61 A), spots extending ventrally, subrectangular (Fig. 61 B). Posterolateral angles of connexivum with apices black (Fig. 61 A). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite (Fig. 61 B). Proepisternum, densely punctured, with dark band (Fig. 60 B). Evaporatorium concolorous with the surrounding surface (Fig. 61 B). Metasternal process (Fig. 22 F) with arms of anterior bifurcation straight and laterally well 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 orange (Fig. 61 B). Abdomen with spine of segment III rounded (Figs. 22 F; 61 B). Intersegmental areas covered by narrow solid black bands with well-defined margins, reaching the lateral spots (Fig. 61 B). Pseudosutures solid black with well-defined margins (Fig. 61 B). Median longitudinal black band incomplete (Fig. 61 B). Trichobothria both parallel to the spiracle.

Male genitalia, posterolateral angles of the pygophore developed, projected laterally, apices internally with spots blacks (Fig. 22 A–C). Superior processes of the genital cup subrectangular, thick, in flattened, coarse and slightly concave posterior view, continuing ventrally in a crenulate, long and high carina (Fig. 22 B, D–E, crenulate carina barely visible). Parameres (Fig. 22 D–E) with black margins; anterior lobe rounded; dorsal lobe subtriangular; posterior lobe subrectangular, with curved apex. Proctiger, posterior face subtriangular, reddish posterior half (Fig. 22 D–E). Ventral surface densely punctuated; presence of dark spots laterally and medially (Fig. 22 C). Ventral rim setose, with medial tuft (Fig. 22 A, C–E); with expansions undeveloped and brown (Fig. 22 C). Female genitalia. Unknown.
