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.
