In the subgenus, C. (G.) fulgidus martinezi  subsp. nov. is separated by the following combination of characters: meso- and metafemora ventral surface rugose on its posterior half ( Fig. 1DView Fig); dorsal surface of pronotum and elytral disc with similar metallic green metallic colouration ( Fig. 3BView Fig); metasternal anterior lobe slightly convex ( Fig. 1EView Fig); profemur with a tooth on its anterior border. Paramera in lateral view ( Fig. 1IView Fig): flattened; apex truncated; upper angle rounded; lower angle acute, forming a spine or tooth. Internal sac ( Fig. 7View 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.


The specific epithet refers to Antônio Martínez (1922–1993), Argentinean taxonomist, author of Goniocanthon  and of several other taxa of Scarabaeinae  .

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).
