Figs 3B , 7–8

Diagnosis

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. 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 (1922–1993), Argentinean taxonomist, author of Goniocanthon and of several other taxa of Scarabaeinae .

Distribution

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).
