Placed into the synonymy of Pseudoeurycea by Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 178; Vieites, Nieto-Roman, Wake, and Wake, 2011, Mol. Phylogenet. Evol., 59: 632, suggested that existing data might be wrong and retained Ixalotriton. Rovito, Parra-Olea, Recuero, and Wake, 2015, Zool. J. Linn. Soc., 175: 167–188, resurrected Ixalotriton based on a general partition of Pseudoeurycea. Jaramillo-Martinez, De la Riva, Guayasamin, Chaparro, Gagliardi-Urrutia, Gutiérrez, Brcko, Vilà, and Castroviejo-Fisher, 2020, Mol. Phylogenet. Evol., 149 (106841): 6, provided trees that suggested that recognition of Ixalotriton renders Pseudoeurycea paraphyletic.
