This species of anole is a small lizard (or moderately-sized for an anole), adults measuring 40 to 44 mm (1.6 to 1.7 in) from snout to vent in males, in females to 46 mm (1.8 in).

The male does not have a dorsal crest or tail fin which is common in many of the anole lizards of Puerto Rico.
The species' range of color is from gray to brownish gray.
It has a pale colored, hour-glass shaped spots from the nape of its neck to its tail, and also has a black, crescent-shaped patch behind the eye.
It has distinct black or darker markings running down the nape of its neck and its back, which are more noticeable on males.
Its flanks are marked with small dark spots.
The throat of this anole has raised brown ridges and the dewlap color is orange with light yellow scales, or "bright orange and yellow toward the margins".
The dewlap is rather large.
The tail is slightly compressed, with the eight or nine vertical rows of weakly keeled scales being arranged in a clearly whorled or verticillate pattern, and the upper margin (edge) of the tail being strongly toothed.
The tail measures 51 to 75 mm (2.0 to 3.0 in) in length.

In females the dewlap much smaller than it is in the male, and it is colored gray, with some pale orange in the centre near the throat.
Unlike in many other anoles, in this species the juveniles have the same coloration and color patterns as do the adults.
Reinhardt and Lütken provide a comparison table of anatomical dimensions of the males and females, with the females being slightly smaller in all measured characteristics according to them (although see above).

It has four or five rows of loreal scales.
There are zero to one scales between the supraorbital ridges, and one to three scales between the interparietal and supraorbital semicircular area.
There are six postrostral scales, six postmental scales, and the subocular scales are in broad contact with the supralabial scales.
The supradigital scales only have a single keel (are unicarinate).
