Hyla hallowellii has a small and slender body. The snout is truncate and the canthus is blunt. Nostrils are nearly on the tip of the snout. The typmanum is circular, about 2/5 of the eye diameter. Fingers and toes end in round adhesive discs. Forelimb webbing is well developed while hindlimb webbing is only moderately so. The skin on the back is almost smooth. There is a large median subgular vocal sac and a pair of slit-like openings. Nuptial pads are present in the male and are a grayish yellow.

Karyotype - 2n=24, with 6 large pairs and 6 small pairs

Taxonomy - A population from Amamioshima Is. was once declared a subspecies H.h. schmidti but this is now thought to be invalid. One specimen from Iriomotejima Is. displays some unique morphology but no similar specimens have been collected.
