Distribution and sampled locations (type locality was only sampled for a few species) for (a) recognized, synonymized, and putative undescribed species of the genus Ictalurus; (b) native and translocated distribution and sampled locations for Ictalurus punctatus, and (c) distribution and sampled locations for species of the furcatus group. Each colored polygon represents the geographic range of species validated in our molecular study. Gene sequences of ictalurids from Canada and USA localities were obtained from Genbank. All three maps were generated in this study from records for distinct taxa of Ictalurus
