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
); dorsal surface of pronotum and elytral disc with similar metallic green colouration (
Fig. 2B
); metasternum anterior lobe strongly convex (
Fig. 1B
); profemur with a tooth on its anterior border. Paramera: on lateral view (
Fig. 1G
): flattened; apex truncated; upper angle rounded; lower angle acute, forming a spine or tooth. Internal sac (
Fig. 5
): 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)
.
