See account by Lynch and Myers, 1983, Bull. Am. Mus. Nat. Hist., 175: 523–530, who noted that this species may be the sister-species of Eleutherodactylus longirostris plus Eleutherodactylus talamancae, and may contain unrecognized sibling species. In the Eleutherodactylus (Craugastor) fitzingeri group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 222. See account by Savage, 2002, Amph. Rept. Costa Rica: 238–239, who included this species in his Eleutherodactylus fitzingeri series, Eleutherodactylus fitzingeri group, and detailed the confusion in the literature of this species with Eleutherodactylus longirostris. In the Craugastor fitzingeri series, Craugastor fitzingeri species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 37, and Padial, Grant, and Frost, 2014, Zootaxa, 3825: 122. Köhler, 2011, Amph. Cent.
