Geographic range :

A. wattsi is native to Antigua, and has also been introduced to Saint Lucia.

Taxonomy :

A. pogus was formerly described as a subspecies of A. wattsi. The taxonomy of two further subspecies, sometimes described as A. schwartziand A. forresti, is unclear. At a minimum, the three taxa 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.

Etymology :

The specific name, wattsi, is in honor of Dr. Sir Francis Watts who became the Commissioner of Agriculture for the West Indies.[1]

The specific name or subspecific name, schwartzi, is in honor of American herpetologist Albert Schwartz.[1]
