Comment

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. Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 411, recovered Ixatotriton as the sister taxon of Parvimolge and outside of a group composed of Isthmura, Aquioeurycea, and Pseudoeurycea.
