Range DescriptionUntil recently, this species was known only from two specimens, collected at St. David Parish and St. Andrew Parish, Grenada in 1968. These sites are less than 20 km apart. The snake was rediscovered in 2010 on the slopes above Chatham Bay on Union Island, St. Vincent and the Grenadines (Quinn et al. 2010, Rivera Rodríguez et al. 2011). Although searches have been conducted on other islands, they have to date revealed no evidence of other populations. The species has been reported from sea level to 179 m asl.
It is unlikely that more than 50% of the land area on Grenada supports suitable habitat for this species, and it is expected to be restricted to the vicinity of Chatham Bay on Union Island. Based on this, the species has an estimated maximum extent of occurrence of 156 km². Its area of occupancy is unknown, although the extent of habitat believed to be capable of supporting this species in Chatham Bay is as small as 0.523 km² (see Bentz et al. 2011).
