In the subgenus,

subsp. nov. is separated by the following combination of characters: meso- and metafemora ventral surface rugose on its posterior half (
Fig. 1D
); dorsal surface of pronotum and elytral disc with similar metallic green metallic colouration (
Fig. 3B
); 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 (
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 Antônio Martínez (

Taxonomic remarks
This subspecies is cited for
Colombia
(
Medina
et al.
2001
) and
Peru
(
Ratcliffe
et al.
2015
) as
Canthon (Goniocanthon) smaragdulus
because of its green metallic sheen, which allows it to be confused with the northern subspecies
C. (G.) smaragdulus subviridis
stat. rev. (diagnosed above). This subspecies is cited as
Canthon fulgidus
for Satipo province,
Peru
(
Balthasar 1951
).
