Critically endangered. Regional endemic; extant only on Montserrat and Dominica. Volcanic activity from the late 1990s through 2012 caused habitat destruction, coupled with the arrival of Batrachochytrium dendrobatidis in 2009, decimating the population.
Including marine turtles and introduced species, there are 15 reptile species on Montserrat. Two are endemic: the Plymouth anole (Anolis lividus) and the Montserrat galliwasp (Diploglossus montisserrati).
Regionally endemic to Montserrat and Saba. No current evidence of green iguana.[3] The Saban black iguana is darker coloured than the other subspecies of green iguana, with colouration deepening in older individuals. It possesses a noticeable black patch between the eye and tympanum.
^Malhotra & Thorpe 1999 also includes Eleutherodactylus martinicensis in its species checklist for Montserrat, at p. 117, but this is not supported by the main text, which describes only three amphibian species for the island, nor do other sources support the presence of this species.
^Conservation status, where available, is from the IUCN Red List and is indicative of the status of the species as a whole, not just populations on Montserrat.
