Oryssomus calix sp. nov.

( Fig. 2 View FIGURE 2 )

Description of holotype (male). Length 3.82, width 2.81 mm. Form elongate oval, widest at middle of elytra, flattened dorsoventrally ( Fig. 2 View FIGURE 2 C). Dorsal and ventral general color reddish brown ( Figs. 2 View FIGURE 2 A, B). Outline of pronotum and elytron discontinuous. Antenna, mouthparts, hypomera, epipleura and legs reddish brown. Clypeus and frons joined at abrupt angle. Pronotum translucent; finely, densely punctured, punctures uniform in size, with a slight depression at lateral sides; pubescence of semidecumbent yellowish hairs; with black spot at base ( Fig. 2 View FIGURE 2 D). Elytra reddish brown with a black spot chalice-shaped in the middle, not reaching humeral callus ( Fig. 2 View FIGURE 2 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; each puncture with long, yellow, decumbent seta. Abdominal ventrites coarsely punctured, punctures separated by about twice a diameter, punctures becoming coarser laterally and on last ventrite. First abdominal ventrite with postcoxal line extending beyond middle of ventrite ( Fig. 2 View FIGURE 2 E). Genitalia with basal lobe equal in length to paramere, lateral margin slightly thickened, parameres slightly curved in lateral view ( Figs. 2 View FIGURE 2 G, H); sipho sinuous, apex nearly membranous, unmodified ( Fig. 2 View FIGURE 2 F).

Female. Length 4.21, width 3.02 mm. Similar to male in all aspects externally. Genitalia with genital plates elongate, styli with setae; spermatheca elongate, unmodified ( Fig. 2 View FIGURE 2 I).

Etymology. The name of this species refers to the shape of black spot of the elytra.

Discussion. Oryssomus calix sp. nov. is similar to O. guillermo sp. nov. and O. unimaculatus , but is clearly distinguished by the chalice-shaped spot on the elytra, and the genitalia.
