Ameiva praesignis — Dusky Ameiva
Some other names for this species:
Giant Ameiva, Amazon Racerunner, Borriguerro Ameiva
This species was split from Ameiva ameiva in 2011. The ones in southern Florida were determined to be this new species.
I ran across two of these colorful, speedy, and non-cooperative lizards while photographing Gray's Spiny-tailed Iguanas on the former grounds of the Crandon Park Zoo. Apparently this is another species that escaped from its former cages and has since formed a long-term population.
