( Fig. 2 ) FIGURE 2. Oryssomus calix sp. nov. (A–D) Habitus: (A) dorsal; (B) ventral; (C) lateral; (D) frontal view. (E) Abdomen; (F–H) male genitalia: (F) sipho; (G) tegmen, ventral; (H) lateral view; (I) female terminalia, coxites and spermatheca. Description of holotype (male) . Length 3.82, width 2.81 mm . Form elongate oval, widest at middle of elytra, flattened dorsoventrally ( Fig. 2 C). Dorsal and ventral general color reddish brown ( Figs. 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 D). Elytra reddish brown with a black spot chalice-shaped in the middle, not reaching humeral callus ( Fig. 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 E). Genitalia with basal lobe equal in length to paramere, lateral margin slightly thickened, parameres slightly curved in lateral view ( Figs. 2 G, H); sipho sinuous, apex nearly membranous, unmodified ( Fig. 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 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.
