Diagnosis

In the subgenus, C. (G.) smaragdulus subviridis stat. rev. is separated by the following combination of characters: ventral surface of meso- and metafemora smooth ( Fig. 1A View Fig ); dorsal surface of pronotum and elytral disc with similar metallic green colouration ( Fig. 2B View Fig ); metasternum anterior lobe strongly convex ( Fig. 1B View Fig ); profemur with a tooth on its anterior border. Paramera: on lateral view ( Fig. 1G View Fig ): flattened; apex truncated; upper angle rounded; lower angle acute, forming a spine or tooth. Internal sac ( Fig. 5 View Fig ): 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.

Taxonomic remarks

Canthon smaragdulus subviridis stat. rev. was described as a variety of C. speculifer ( Schmidt 1922) . It was also listed as a variety of Goniocanthon smaragdulus in a catalogue, but Vulcano & Pereira (1964) did not explicitly treat this as a taxonomic act, nor did they consult the type material. Finally, this taxon is also treated as a variety of C. smaragdulus in a catalogue by Vaz-de-Mello (2000).
