In the Hyla versicolor group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 102. Hyla chrysoscelis is one of a pair of cryptic species with Hyla versicolor. Holloway, Cannatella, Gerhardt, and Hillis, 2006, Am. Nat., 167: E88-E101, provided an analysis that discussed the role of Hyla chrysoscelis in the formation of the tetraploid Hyla versicolor, discussed previous literature and provided a revised range.
