P. corax is a melanistic species, superficially similar in its dark coloration and scalation to Pholidoscelis atratus and Pholidoscelis corvinus, other species also found on small, barren Caribbean islands.

This is believed to be due to independent adaptation to the similar local environments.

[4] In 2016, the species was moved to Pholidoscelis based on genetic sequencing and phylogenetic analyses.

[1] Censky's ameiva is listed as endangered on the IUCN Red List due to its small population (estimated at approximately 250 mature adults) and extremely limited distribution/habitat, an area less than 0.049 km2 (12 acres) in size.

[1] It is likely vulnerable to development, invasive mammal introduction, seasonal loss of vegetation during hurricanes, and declining seabird numbers (a food source).
