We describe three new species: Canthon mezcalis Moctezuma, Sá:nchez-Huerta, and Halffter sp. nov. from the Valles Centrales region in Oaxaca, Mexico: Canthon hondurensis Moctezuma and Sá:nchez-Huerta sp. nov. from Honduras: and Canthon woodruffi Moctezuma and Sá:nchez-Huerta sp. nov. from Guanacaste, Costa Rica. Through the examination of external and genital morphology, Bayesian inference, and genetic distances based on the Kimura two-parameter model of nucleotide substitution, we confidently determined that the C. indigaceus species group is a monophyletic unit, which is integrated by a set of cryptic species.
