Diagnosis

In the subgenus, C. (G.) fulgidus pereirai subsp. nov. is separated by the following combination of characters: meso- and metafemora ventral surface rugose on posterior half ( Fig. 1D ); dorsal surface of pronotum and elytral disc with similar metallic red colouration ( Fig. 3C ); metasternal anterior lobe slightly convex ( Fig. 1E ); profemur with a tooth on its anterior border. Paramera in lateral view ( Fig. 1I ): flattened; apex truncated; upper angle rounded; lower angle acute, forming a spine or tooth. Internal sac (identical to Canthon (G.) fulgidus martinezi subsp. nov., see Fig. 7 ): FLP involving A forming a central duct with spiniform apex. SA lateral to FLP + A complex present. MP distal to A, not divided, semicircular, widely emarginated; FLP + A complex involved by MP.

Etymology

The specific epithet refers to Francisco Silvério Pereira (1913–1991), priest, taxonomist, author of Goniocanthon and of several other taxa of Scarabaeinae .
