Iguanainsularis (Iguanidae) from the southern Lesser Antilles: An endemic lineage endangered by hybridization.

ABSTRACT: The newly described horned iguanaIguanainsularis from the southern Lesser Antilles is separated in two easily recognized subspecies: I.insularissanctaluciae from St. Lucia and I.insularisinsularis from the Grenadines. Its former description is completed by the use of 38 new samples for genetic and morphological analysis. Seventeen microsatellites were used to estimate genetic diversity, population structure and the level of introgression with other Iguana species over nearly the whole range of the species. ND4 and PAC sequences were also used to better characterize hybridization and to complete the description of this lineage. The I.insularis population of St. Vincent shows a high level of introgression from I.iguana whereas in the Grenadines, most
