Geographic Occurrence

Natural Resident: Ecuador

Endemic: Ecuador


In the Eleutherodactylus myersi assembly of the Eleutherodactylus unistrigatus group; in the more inclusive (and monophyletic) Eleutherodactylus pyrrhomerus assembly, and the sister-species of Eleutherodactylus ocreatus, according to Lynch, 1984, Herpetologica, 40: 237 (as Eleutherodactylus trepidotus). See brief account (as Eleutherodactylus trepidotus) by Lynch and Duellman, 1980, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 69: 58–59. In the Eleutherodactylus (Eleutherodactylus) myersi series, Eleutherodactylus myersi group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 233 (as Eleutherodactylus trepidotus). Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 129, provided distributional data for Ecuador (as Eleutherodactylus trepidotus).
