[Note: Camponotus geralensis was proposed as a replacement name for Camponotus macrocephalus Emery, 1894: Shattuck & McArthur, 1995: 122, a junior secondary homonym of Colobopsis macrocephala (Erichson, 1842) when both names were combined in Camponotus. As the two names now occupy different genera, the replacement name is redundant.].
