A newly discovered endemic species of melanistic black iguana (Iguana melanoderma) was discovered in Saba and Montserrat islands (Lesser Antilles). The species was previously considered to represent melanistic individuals of the green iguana (Iguana iguana). Recently it was reclassified as a separate species based on a number of genomic distinctions and consistent morphological characteristics.
