A cryptic lineage within the pupfish Cyprinodon dearborni suggests multiple colonizations of South America

The coastal South American species Cyprinodon dearborni contains two lineages distinct at both mitochondrial and nuclear loci. One appears to be a long‐term South American endemic, whereas the other is a more recent colonizer related to the widespread Cyprinodon variegatus.
