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. Cline, 2005, in Lannoo (ed.), Amph. Declines: 449–452, and Dodd, 2013, Frogs U.S. and Canada, 1: 250–262, provided accounts that summarized the literature of the species and discussed the difficulty of identification between this species and the closely-related Hyla versicolor. Indeed, the original holotype of Hyla chrysoscelis had to be replaced by a neotype because the holotype turned out to be a representative of Hyla versicolor on histological examination (Fitzgerald, Smith, and Guillette, 1981, J. Herpetol., 15: 356–360). Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 66–67, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 199–201, provided an account of larval morphology and biology. Tye, Geluso, and Harner, Herpetol. Rev., 48: 382–382, provided a record for central Nebraska, USA, and discussed the range and possibility of introductions in Nebraska and South Dakota, USA. Ruhe, Poston, and Urban, 2019, Herpetol. Rev., 50: 96–97, provided a record from Washington County, Pennsylvania, USA.
