In the Eleutherodactylus unistrigatus group. Distribution expanded by Duellman, 1993, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 21: 149. In the Eleutherodactylus (Eleutherodactylus) martinicensis series, Eleutherodactylus unistrigatus group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 226. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 57, and Köhler, 2000, Bonn. Zool. Monogr., 48: 69, consider this species possibly to occur in Bolivia. Duellman, 2005, Cusco Amazonico: 269–270, provided an account (adultl morphology and life history). In the Pristimantis (Pristimantis) unistrigatus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 128. Not assignable to a species group according to Padial, Grant, and Frost, 2014, Zootaxa, 3825: 127. See Duellman and Lehr, 2009, Terrest.-breeding Frogs in Peru: 182-183, for brief account.  Ortega-Andrade, Deichmann, and Chaparro, 2021, S. Am. J. Herpetol., 21: 41–64, discussed Pristimantis imitatrix, previously confused with Pristimantis academicus and the newly named Pristimantis gagliardi and Pristimantis okmoi, and provided comparative morphology and morphometrics, as well as molecular markers and a discussion of the range.
