The attached diagram has been redrawn from Duellman 2001, the Hylid Frogs of Middle America. Duellman based this diagram on da Silva's phylogeny. Notice the position of Hyla eximia relative to the Hyla versicolor group (which includes Hyla chrysoscelis). In both of the trees of Moriarty and Cannatella (2004), H. chyrsoscelis is basal to Hyla eximia. In Duellman's tree, Hyla eximia is basal to Hyla chrysoscelis. Moriarty and Cannatella's Pseudacris is based on cutting the tree at position B, thus including Hyla crucifer, Hyla cadaverina and Hyla regilla in Pseudacris, making it a heterogeneous genus with some secondarily terrestrial treefrogs with reduced toe pads and also some species traditionally included in Hyla because of their well developed toe pads. An alternative way for delimiting Pseudacris is to apply the cut at position A, thus leaving Hyla crucifer, Hyla cadaverina and Hyla regilla out of Pseudacris. Pseudacris, without these species of Hyla, is much better defined and more homogeneous, since all members are secondarily terrestrial hylids with reduced toe pads.
