A male syntype was studied by Ferreira (1964b) and she transferred this taxon to the subgenus Metacatharsiu s based purely on body size, despite its absence from Balthasar’s (1965) comprehensive work on the subgenus. Subsequently, Metacatharsius was raised to genus level ( e.g. , Montreuil 1998 ) and from re-examination of a male syntype housed in MCST, it has become evident that the original placement of this taxon in the genus Catharsius was correct.
