[3] The specific name, eugenegrahami, is in honor of herpetologist Eugene D. Graham Jr., who was one of the collectors of the holotype.

[4] A. eugenegrahami is endemic to the Département du Nord in northern Haiti where it is only found 9 kilometres (5.6 mi) northeast of Plaisance.

The dewlap (male only) ranges from very dark gray to black, with the edge being lighter.

[5][6] The semi-aquatic anoles are morphologically diverse and do not form a monophyletic group,[5] but there is convergence in certain microstructures of their skin, making it highly hydrophobic.

[6] This results in a thin layer of air on the skin surface when submerged underwater, which they use as an extra air supply for breathing, and it also prevents water from staying on when exiting the water.
