Comment

In the Eleutherodactylus unistrigatus group according to the original publication. In the Eleutherodactylus (Eleutherodactylus) conspicillatus series Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 228. Köhler, 2000, Bonn. Zool. Monogr., 48: 114, 120, provides a brief account. Köhler, 2000, Copeia, 2000: 519, noted that this species may be related to the Eleutherodactylus fraudator group. Padial, McDiarmid, and De la Riva, 2006, Zootaxa, 1278: 49-56, discussed variation, range, and provided the first record for Peru. Padial, Castroviejo-Fisher, Köhler, Domic, and De la Riva, 2007, Herpetol. Monogr., 21: 227-228, provided an account.
