The Pacific Treefrog should be Hyla regilla, not "Pseudacris regilla." Pseudacris is a group of hylid frogs with small toe disks and little webbing between the toes. Hyla regilla does not fit that definition. The toe disks of Hyla regilla is much larger than in Pseudacris. By lumping Hyla regilla with Pseudacris, there is now no way to define Pseudacris.

Hyla regilla is one of the closest relatives of Pseudacris, but it should not be made a member of this genus. Just a minor disagreement I have with the cladists.
