( Figs. 1JView FIGURE 1, 4JView FIGURE 4, 5IView FIGURE 5, 6BView FIGURE 6)

Etymology. Named in honor of Edgar von Harold (1830‒1886), for his valuable contribution in describing new species of scarabs, particularly of the genus Canthon  .

Diagnosis. Specimens of S. haroldi  are readily distinguishable from all other species by the body with metallic sheen, femora and elytra bicolored, and pronotum uniformly colored ( Fig. 1JView FIGURE 1). In addition, males have a diagnostic aedeagus with parameres elongate, subrectangular, not excavated ventrally ( Fig. 4JView FIGURE 4); and endophallus lacking bristles or microbristles close to the FLP sclerite ( Fig. 5IView FIGURE 5).

Description. Body. Oval, lateral edges rounded. Variable metallic sheen. Color. Pronotum, hypomera (except internal margin), metaventrite, most of elytra, abdominal ventrites, pygidium, and middle of femora yellow or light brown. Head, internal margin of hypomera, prosternum, mesoventrite, mesoepisternae, metaepisternae, coxae, trochanters, proximal and distal portions of femora, tibiae, and anterior portion of elytra dark brown or black. Length. 7.3–8.4 mm. Thorax. Anterior angles of pronotum acute (approximately 70°). Lateral margin regularly curved outward, not forming an angle at the middle portion. Elytra. Anterior portion with a continuous black spot somewhat expanded at middle of the anterior portion. Striae thin, punctures inconspicuous. Eighth stria with a thin carina at the anterior portion. Aedeagus. Parameres symmetrical and elongate, with subrectangular shape, truncate apically ( Fig. 4JView FIGURE 4). Dorsal and ventral margins of parameres substraight. SRP circular, with curved handle-shaped extension ( Fig. 5IView FIGURE 5). FLP I-shaped ( Fig. 5IView FIGURE 5). A+SA with two superposed and elongate sclerites ( Fig. 5IView FIGURE 5). AS I-shaped ( Fig. 5IView FIGURE 5).
