Pseudacris Fitzinger, 1843
Pseudacris Fitzinger, 1843, Syst. Rept.: 31. Type species: Rana nigrita LeConte, 1825, by monotypy.
Chorophilus Baird, 1854, Proc. Acad. Nat. Sci. Philadelphia, 7: 59. Type species: Rana nigrita LeConte, 1825, by original designation. Synonymy with Pseudacris by Cope, 1889, Bull. U.S. Natl. Mus., 34: 338, who, however, continued to use Chorophilus. The use of Pseudacris as the older name begins with Stejneger and Barbour, 1917, Check List N. Am. Amph. Rept.: 30. Fouquette and Dubois, 2014, Checklist N.A. Amph. Rept.: 345, regarded the original publication date to be 1856, but see Fox, 1913, Proc. Acad. Nat. Sci. Philadelphia, Index, 1812–1912: vii–xiv.

Rept., Ed. 6: 73. Synonymy by Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 157; Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 332. Fouquette and Dubois, 2014, Checklist N.A. Amph. Rept.: 345, regarded the original publication date to be 1856, but see Fox, 1913, Proc. Acad. Nat. Sci. Philadelphia, Index, 1812–1912: vii–xiv.

Comment
Dubois, 1984, Alytes, 3: 85–89, regarded Pseudacris as a subgenus of Hyla, following Noble, 1923, Am. Mus. Novit., 70: 1–6, who considered Pseudacris a junior synonym of Hyla. Hedges, 1986, Syst. Zool., 35: 11, placed former Hyla crucifer, Hyla regilla, Hyla cadaverina, and Limnaoedus ocularis in Pseudacris and discussed phylogenetic relationships. Cocroft, 1994, Herpetologica, 50: 420–437, provided a phylogenetic analysis of Pseudacris and disputed Hedges' results, although Silva, 1997, J. Herpetol., 31: 609–613, provided additional evidence and discussion in support of placing these species within Pseudacris. Moriarty and Cannatella, 2004, Mol. Phylogenet. Evol., 30: 409–420, discussed phylogeny in the genus. In the Hylini of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 89, who recognized four groups within the genus (p. 106) noted in the species records. Lemmon, Lemmon, Collins, Lee-Yaw, and Cannatella, 2007, Mol. Phylogenet. Evol., 44: 1068–1082, provided results that corroborated the tree of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 89, and discussed and revised the Pseudacris nigrita group. Lemmon, Lemmon, and Cannatella, 2007, Evolution, 61: 2086–2103, discussed the biogeography of the Pseudacris nigrita group. Lemmon, Lemmon, Collins, and Cannatella, 2008, Zootaxa, 1675: 45–46, also provided a summary of the phylogenetics of the Pseudacris nigrita group. Barrow, Ralicki, Emme, and Lemmon, 2014, Mol. Phylogenet. Evol., 75: 78–90, reported on molecular phylogenetics. Fouquette and Dubois, 2014, Checklist N.A. Amph. Rept.: 345–365, employed subgeneric names: 1) Pseudacris for the Pseudacris nigrita and Pseudacris brachyphona groups; 2) Hyliola for the Pseudacris regilla group; 3) Limnaoedus for the Pseudacris crucifer group; and Pycnacris for the Pseudacris ornata group. 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 discussed the taxonomic difficulties associated with the Pseudacris regilla group and the relationship of nominal Pseudacris streckeri and Pseudacris illinoensis. Duellman, Marion, and Hedges, 2016, Zootaxa, 4104: 10, considered Hyliola to be a distinct genus, although Faivovich, Pereyra, Luna, Hertz, Blotto, Vásquez-Almazán, McCranie, Sánchez, Baêta, Araujo-Vieira, Köhler, Kubicki, Campbell, Frost, Wheeler, and Haddad, 2018, S. Am. J. Herpetol., 13: 15, subsequently argued against its recognition. Banker, Lemmon, Hassinger, Holland, Kortyna, Ospina, Ralicki, and Lemmon, 2020, Syst. Biol., 69: 756–773, reported on the molecular phylogenetics of the species, in the sense of including Hyliola as a synonym of Pseudacris, but without mentioning that synonymized name, with special reference to methods. Jadin, Orlofske, Jezkova, and Blair, 2021, Biol. J. Linn. Soc., 132: 612–623, provided a mtDNA analysis that they suggested supported the species distinction (as Hyliola) of Pseudacris regilla, Pseudacris sierra, and Pseudacris hypochondriaca.
