Some authorities put most of the Central and South American anole species (as opposed to the U.S./Caribbean ones) into the genus Norops. This might become the standard soon, but for now there are still many authorities using "Anolis". Thanks to Axel Fläschendräger for helping to identify this anole as Anoilis polylepis (which was appropriate at the time).
