Very similar to the Common Tree Frog (Hyla arborea), but differs from it by usually having a dark spot on the upper lip below the eye, lack of an inguinal loop, and slightly shorter hind legs (when the hind leg is stretched along the body, the tibio-tarsal articulation commonly reaches the posterior edge of the eye). Tympanic membrane smaller than eye. Dorsal skin smooth, ventral skin granular. Coloration and sexual dimorphism are similar to those in the Common Tree Frog (the main difference is the absence of the inguinal loop). Dark lateral band regularly disrupted into spots and partially reduced. The tips of fingers and toes have round adhesive discs. The forelimb webbing is poorly developed. The mean snout-vent length for males is 31 mm (range 26-45 mm) and for females is 35 mm (range 26-41 mm). The nuptial pads in males are yellow.
Karotype: Diploid chromosome (2n) with 6 large pairs and 6 small ones making a total of 24 chromosomes.
