Thirteen of the 14 U.S. species of Hyla are arranged in species groups primarily on the basis of mating-call structure. This is used in conjunction with evidence of genetic compatibility and morphological characters. The versicolor group includes the species versicolor, phaeocrypta, femoralis, arenicolor and baudini. The cinerea group includes cinerea, andersoni, and gratiosa. The squirella group tentatively includes squirella and regilla. Three other species, crucifer, ocularis, and septentrionalis do not appear closely related to any of these groups. The first two of these have calls that show similarities to calls of members of the currently recognized genus Pseudacris.
