The New World checkered beetle genus Callotillus Wolcott, 1911 is revised and the new genus Neocallotillus established. The subspecies Callotillus
elegans
vafer Wolcott is synonymized with the nominal subspecies, Callotillus
elegans
elegans (Erichson), which is transferred to, and designated as the type species of Neocallotillus
gen. n. as Neocallotillus
elegans (Erichson, 1847), comb. n. Two additional species are transferred from Callotillus to the new genus: Neocallotillus
intricatus (Wolcott & Dybas, 1947), comb. n. and Neocallotillus
crusoe (Wolcott, 1923), comb. n., the latter tentatively and based on Wolcott’s original description. Callotillus is now composed of two species: Callotillus
eburneocinctus Wolcott, 1911 and Callotillus
bahamensis Vaurie, 1952. All abovementioned species except Neocallotillus
crusoe are diagnosed and redescribed. In the absence of reference material of Neocallotillus
crusoe, Wolcott’s original description is transcribed. An illustrated key to species is provided. Characters of taxonomic relevance are illustrated and discussed. Updated distribution maps and locality data for all specimens examined are presented.
