Comment

Removed from the synonymy of Eleutherodactylus bransfordii by Miyamoto, 1983, Syst. Zool., 32: 43-51. See comment under Eleutherodactylus bransfordii. In the Eleutherodactylus (Craugastor) rhodopis group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 233. See account by Savage, 2002, Amph. Rept. Costa Rica: 261–262, who included this species in his Eleutherodactylus rhodopis series, Eleutherodactylus rhodopis group. In the Craugastor rhodopis species series, Craugastor podiciferus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 41, and of Padial, Grant, and Frost, 2014, Zootaxa, 3825: 123. Köhler, 2011, Amph. Cent. Am.: 140–191, provided a key to the genera and species of Brachycephaloidea (= Craugastoridae, Eleutherodactylidae) in Central America and provided maps and photographs of the species, including this one. Premontane populations of Costa Rica and Panama referred to Craugastor gabbi by Arias, Chaves, Crawford, and Parra-Olea, 2016, Zootaxa, 4132: 347–363. Twining and Cossel, 2017, Mesoam. Herpetol., 4: 129–136, and Cossel, Twining, Di Stefano, O’Brien, Reich, and Sandoval-Alanis, 2019, Herpetol. Conserv. Biol., 14: 235–249, reported on vocalization. In the Craugastor podiciferus group, Craugastor stejnegerianus clade of Arias, Crawford, Hertz, and Parra-Olea, 2025, PeerJ, 13(e18212): 1–33, who reported on the molecular phylogenetics of the species group and provided a dot map of the distribution.
