Differential diagnoses, updates on distribution ranges, and an illustrated identification key are given for all species of Agamopus. The first record for A. castaneus from Brazil is given. Type specimens of all valid species-group names are studied and illustrated. Notes on the natural history of Agamopus species, as well as brief phylogenetic comments, are presented. The new species Agamopus joker sp. nov. is described based on a male from Paraná, southern Brazil. Lectotypes are designated for Canthon unguicularis Harold, 1883 and Agamopus lampros Bates, 1887. We also propose the transfer of Agamopus convexus Balthasar, 1965 to the Ateuchus ovalis species group (Ateuchus convexus comb. nov.) based on morphological features of the protibiae, clypeal teeth, and the posterior margin of the pronotum and pygidium.
