In the Pseudacris nigrita group of Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 106. Elevated from subspecies status under Pseudacris triseriata by Platz, 1989, Copeia, 1989: 704–712, on the basis of widespread sympatry and differences in call structure (see Platz and Forester, 1988, Copeia, 1988: 1062–1066). See nomenclatural discussion by Dubois, 1984, Alytes, 3: 86–87. Lemmon, Lemmon, Collins, Lee-Yaw, and Cannatella, 2007, Mol. Phylogenet. Evol., 44: 1068–1082, redelimited the species. Dodd, 2013, Frogs U.S. and Canada, 1: 371–384, provided an account that summarized the relevant literature. Elliot, Gerhardt, and Davidson, 2009, Frogs and Toads of N. Am.: 94–95, provided an account, photos, and advertisement call. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 210–212, provided an account of larval morphology and biology. Rogic, Tessier, Nöel, Gendron, Branchaud, and Lapointe, 2015, Herpetol. Rev., 46: 1–7, discussed the range in southern Ontario and southern Quebec, Canada, on the basis of calls and mtDNA analysis. Painter, Stuart, Giermakowski, and Pierce, 2017, Western Wildlife, 4: 36, commented on the status and county range in New Mexico, USA.  Rogic, Tessier, and Lapointe, 2019, J. Herpetol., 53: 89–95, characterized genetically he populations of southern Ontario and southern Quebec, Canada, for purposes of conservation.
