A. pogus was formerly described as a subspecies of A. wattsi. The taxonomy of two further subspecies, sometimes described as A. schwartzi and A. forresti, is unclear. At a minimum, the three types are very closely related, and similar in appearance, ecology, and behavior. A. w. schwartzi is found on Sint Eustatius, Saint Kitts, and Nevis. A. w. forresti is endemic to Barbuda.
