General color black, middle of thorax and abdomen dark brown. Outline of pronotum and elytron discontinuous. Antenna, mouthparts, hypomera, epipleura and legs yellowish brown. Clypeus and frons joined at abrupt angle. Pronotum black with yellowish brown triangular spots, causing the black markings to appear w-shaped; finely, densely punctured, punctures uniform in size; pubescence of semidecumbent yellowish hairs (Fig. 5 D). Elytra black with a narrow yellowish brown border on the posterior 1/3 of elytra (Fig. 5 A). Elytral punctures coarse, dense, slightly larger than on pronotum and similarly dense, uniform in size. Metaventrite finely, sparsely punctured medially and anteriorly; coarsely, densely punctured laterally and posteriorly with punctures large, often confluent (Fig. 5 B); each puncture with long, yellow, decumbent seta. Abdominal ventrites coarsely punctured, punctures separated by about twice a diameter, punctures becoming coarser laterally and on first ventrite. First abdominal ventrite with postcoxal line extending beyond middle of first ventrite (Fig. 5 E). Genitalia with genital plates triangular, elongate, styli with setae; spermatheca elongate, slender at apex (Fig. 5 F).

Male. Unknown.

Etymology. This species is named in honor of the dedicated entomologist, Paschoal Coelho Grossi.

Discussion. Oryssomus paschoali sp. nov. differs from other species in the genus by the elytral and pronotal color. The flattened body shape and the sides almost parallel are as in Neoryssomus germainii and N. variabilis, but these differ in color pattern, number of antennomeres and body size.
