Hyla regilla Baird and Girard, 1852, Proc. Acad. Nat. Sci. Philadelphia, 6: 174. Syntypes: Not stated; USNM 9182 (Puget Sound), USNM 15409 (Sacramento River) according to Cochran, 1961, Bull. U.S. Natl. Mus., 220: 58, and MCZ 2149 (exchanged from USNM according to Barbour and Loveridge, 1929, Bull. Mus. Comp. Zool., 69: 280); USNM 9182 designated lectotype by Jameson, Mackey, and Richmond, 1966, Proc. California Acad. Sci., Ser. 4, 33: 553. Type locality: "Sacramento River, in Oregon [now California] and Puget Sound [, Washington]", USA; restricted (in error) to "Seattle, King County", Washington, USA, by Smith and Taylor, 1950, Univ. Kansas Sci. Bull., 33: 363; restricted to "Sacramento County, California", USA, by Schmidt, 1953, Check List N. Am. Amph. Rept., Ed. 6: 72; restricted to "Fort Vancouver, Washington", USA, by Jameson, Mackey, and Richmond, 1966, Proc. California Acad. Sci., Ser. 4, 33: 553, a locality they associated with USNM 9182, although this location is on the Columbia River on the Oregon line, and the published type locality is on Puget Sound at the northwestern side of Washington.

Comment

In the Pseudacris regilla group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 106. Before its transferral to Pseudacris, considered a member of the Hyla eximia group. See (as Hyla regilla) Jameson, Mackey, and Richmond, 1966, Proc. California Acad. Sci., Ser. 4, 33: 551–620, and Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 484–493; seven subspecies are recognized. Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 222–223, provided a brief account, figure, and map. Highton, 2000, in Bruce et al., Biol. Plethodontid Salamanders: 234, discussed the previously published allozyme evidence (including that of Case, Haneline, and Smith, 1975, Syst. Zool., 24: 281-295) and suggested that the existing genetic data are not consistent with this being a single species. Recuero, Martínez-Solano, Parra-Olea, and García-París, 2006, Mol. Phylogenet. Evol., 39: 293–304, partitioned this taxon into Pseudacris pacifica (northern part of range), Pseudacris regilla (central part of former range), and Pseudacris hypochondriaca (southern part of former range). However, due to an inadvertent misapplication of names, the oldest names for the northern range is actually Pseudacris regilla and for the central part of the range the oldest available name is Pseudacris sierra (Recuero, Martínez-Solano, Parra-Olea, and García-París, 2006, Mol. Phylogenet. Evol., 41: 511). Rorabaugh and Lannoo, 2005, in Lannoo (ed.), Amph. Declines: 478–484, provided a detailed account that summarized the literature (in the sense of including Pseudacris sierrae and Pseudacris hypochondrialis.  Dodd, 2013, Frogs U.S. and Canada, 1: 400–416, provided an account that summarized the relevant literature and suggested (citing a personal communication from Gregory Pauly) that recognition of Pseudacris sierrae and Pseudacris hypochondrialis is premature because the published evidence might be wrong.  Barrow, Ralicki, Emme, and Lemmon, 2014, Mol. Phylogenet. Evol., 75: 78–90, reported on species tree estimation, reported on significant mtDNA and nuDNA discordance due to inter-species introgression and possible incomplete sorting and discussed the taxonomic difficulties associated with the recognition of species within Pseudacris regilla sensu lato. However, these author took no taxonomic remedy and the allozymic evidence presented by Case, Haneline, and Smith, 1975, Syst. Zool., 24: 281–295, remains consistent with recognition of three species within Pseudacris regilla sensu lato: Pseudacris regilla, Pseudacris sierrae, and Pseudacris hypochondriaca. Nevertheless, as suggested by Barrow et al., 2014, considerable work on the Pacific Coast of the USA is warranted.  Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 108–111, provided an account (in the sense of including Pseudacris hypochondriaca and Pseudacris sierrae), photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 208–209, provided an account of larval morphology and biology.
