Diagnosis

In the subgenus, Canthon staigi can be distinguished by the following combination of characters. Dorsally elytra and pronotum with blue or green colouration and blue and green reflections ( Fig. 1A View Fig ). Metafemora with several punctures at base, with no groove ( Fig. 1B View Fig ). Hypomere with thin transverse carina between the anterior and posterior portions, projecting to the median region, anterior region not excavated ( Fig. 1C View Fig ). Propygidium with strong V-shaped carina between pygidium and propygidium ( Fig. 1D View Fig ). Parameres flattened in lateral view ( Fig. 2A View Fig ); truncated apex, sub-straight, never sinuous; slightly rounded upper angle; straight lower angle. In dorsal view ( Fig. 2B View Fig ): membranous portion separates the parameres, wider in the central region and narrower at the base and apex. Internal sac ( Fig. 2 View Fig C–D) with peripheral fronto-lateral sclerite (FLP) involving axial sclerite (A), both structures forming a complex with a central duct, wider at the base, gradually narrowing toward the apex, which is much finer; subaxial sclerite (SA) lateral to the FLP + A complex; peripheral medial sclerite (MP) lateral in relation to FLP + A, this with the sharper part passing within a semiduct formed by MP; MP with a central denticle at the inner margin ( Fig. 2C View Fig ); superior right peripheral sclerite (SRP) circular and with semi-circular lateral prolongation.

Remarks

This species was described by Pereira (1953) in the same publication as the description of the subgenus, for which the author simultaneously designated it as the type species.

Distribution

Atlantic Forest, from Pernambuco to Paranaguá, southeast of the state of Paraná. In the literature there are records for Argentina and Paraguay ( Pereira & Martínez 1956; Martínez 1959; Halffter & Martínez 1967), but we have not examined any specimens from these localities ( Fig. 10 View Fig ).
