prepollex

The digits (and metacarpals) are considered by Ritland to be 1-4, in addition to the prepollex, rather than 2-5.

There are no ventrolateral glands, glandular area on the chin, or enlarged prepollex.

Males in the Hyla maxima group have a protruding bony prepollex like that characteristically found in Plectrohyla.

Breeding males have dark brown nuptial excrescences on the prepollex.

Each of the last two has a bony prepollex, rather rugose skin on the dorsum, and more squat body.
