Elytral punctures intermixed coarse and fine, dense, slightly larger than on pronotum; sparse in the discal area. Antenna, mouthparts, hypomera, epipleura, and legs reddish yellow. Metaventrite finely, sparsely punctured medially and anteriorly; coarsely, densely punctured laterally and posteriorly with punctures large, often confluent ( Fig. 9 View FIGURE 9 B). Abdominal ventrites coarsely punctured, punctures separated by about a diameter or less, punctures becoming coarser laterally. First abdominal ventrite with postcoxal line complete, extending beyond middle of first ventrite; precoxal area coarsely punctured on base of cavity ( Fig. 9 View FIGURE 9 E).
