Remarks.

Lacordaire’s (1856) rejection of Ancognatha created a case of homonymy between the names C. castanea (Erichson) and C. castanea (Olivier). Cyclocephala peruana was proposed as a replacement for the junior homonym C. castanea (Erichson) ( Harold 1869a). Subsequent authors did not use this replacement name (e.g., Arrow 1911, 1937b), with Endrődi (1966) stating that it was an “incorrect” new name.
