Williams et al. (Syst. Entomol. 36: 180–191) discovered that all former members of the Dasymutilla bioculata species-group were synonymous. Here we present a study of Mexican and Caribbean species that closely resemble D. bioculata (Cresson). Dasymutilla bouveiri (André), Dasymutilla chionothrix Manley & Pitts, Dasymutilla concordia Manley & Pitts, Dasymutilla insulana Mickel, Dasymutilla latebalteata (Cameron), Dasymutilla nocticaro Manley & Pitts, Dasymutilla truxali Manley & Pitts, and Dasymutilla Veracruz Manley & Pitts are transferred to the D. bioculata species-group based on morphological similarities with D. bioculata. Placement in the D. bioculata species-group, coupled with overlapping disparate ranges, facilitate the following synonymies. D. truxali is a junior synonym of D. chionothrix. D. Veracruz is a junior synonym of D. latebalteata. D. concordia is a junior synonym of D. nocticaro. Genaro (Caribbean J. Sci. 33: 263–268) provided a key to the males of the Caribbean species, including Dasymutilla bouvieri and D. insulana, but these males were not satisfactorily described. Full descriptions are given for these males and diagnoses are provided for all members of the D. bioculata species-group.
