The two species of Galápagos land iguanas (Conolophus subcristatus and C. pallidus) are listed as 'vulnerable' species by the International Union for the Conservation of Nature (IUCN Red List; http://www.iucnredlist.org). Here, we report on the isolation and characterization of 10 microsatellite markers using 562 individuals sampled on all Galápagos islands where Conolophus species occur today. We show that these 10 loci are highly polymorphic and display diagnostic alleles for five out of the six island populations. These markers will be useful for Conolophus population genetic analyses as well as for guiding ongoing captive breeding programmes.
