abstract = {Transitions between sexual and unisexual reproductive modes have significant consequences for the evolutionary trajectories of species. These transitions have occurred numerous times in vertebrates and are frequently mediated by hybridization events. Triploid unisexual vertebrates are thought to arise through hybridization between individuals of a diploid unisexual lineage and a sexual species, although additional evidence that confirms this mechanism is needed in numerous groups. North American whiptail lizards (Aspidoscelis) are notable for being one of the largest radiations of unisexual vertebrates, and the most diverse group of Aspidoscelis includes numerous triploid lineages that have no known diploid unisexual ancestors. This pattern of ?missing? ancestors may result from the short evolutionary lifespan of unisexual lineages, selective advantages of polyploidy, or could suggest that alternative mechanisms of triploid formation are operating in nature. We leverage genomic, morphological, and karyotypic data to describe a new diploid unisexual whiptail and show that it is likely the unisexual progenitor of an extant triploid lineage, A. opatae. We also resolve patterns of polyploidization within the A. sexlineatus species group and test predictions about the morphological outcomes of hybridization.}
