Harminius castaneus Fairmaire was described as a Eucnemidae, but all subsequent authors placed it among the Elateridae, usually as a valid genus and species near Athous. Neither the original description nor the illustration bear any resemblance to the species currently called castaneus. No original material could be found, therefore it is questionable as to what species Fairmaire described. To conserve nomenclatorial stability, application is being made to the International Commission on Zoological Nomenclature to set aside any previous type-species designation and to designate spiniger Candèze as the type-species of Harminius and Pseudocorymbites. Consequently, castaneus is considered as a species incertae dubia. An attempt is made to straighten out the usage of the names castaneus auct., spiniger Candèze, and florentinus Desbrochers. Previously castaneus auct has referred either to spiniger or florentinus (mostly to spiniger), whereas both are now recognized as valid species in the subgenus Harminius; gigas Reitter also belongs in the same subgenus. Pseudocorymbites Fiori is isogenotypic with Harminius and the subgenera Diacanthous Reitter and Megathous Reitter remain valid under Harminius, as in most catalogues.
