Comment

Grünwald, Reyes-Velasco, Franz-Chávez, Morales-Flores, Ahumada-Carrillo, Rodriguez, and Jones, 2021, Amph. Rept. Conserv., 15(e272): 1–35, provided key comparative characters (external morphology and advertisement call) for identification of members of their Eleutherodactylus nitidus group, as well as a molecular tree to place the species. In addition, these authors removed this species from the synonymy of Eleutherodactylus nitidus, where it had been placed by Dixon, 1957, Texas J. Sci., 9: 390. In the Eleutherodactylus (Syrrhophus) nitidus clade of Hernández-Austria, García-Vázquez, Grünwald, and Parra-Olea, 2022, Syst. Biodiversity, 20 (1: 2014597): 1–20, who reported on molecular phylogenetics.
