Distribution

The La Escalera region in Venezuela, the southern base of Mount Roraima in Venezuela (type locality) and the north-eastern base of Mount Roraima in Guyana (Double Drop Falls), the slopes of Maringma-tepui along the border between Guyana and Brazil, Mount Ayanganna in Guyana, the Wokomung Massif in Guyana and Kaieteur National Park in Guyana, between ca 600 and 1800 m and probably restricted to the pristine submontane and montane rainforests of the Pantepui uplands and highlands, east of the Gran Sabana. 

Comment

In the Eleutherodactylus (Eleutherodactylus) martinicensis series, Eleutherodactylus unistrigatus group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 228. See account by Rivero, 1961, Bull. Mus. Comp. Zool., 126: 80. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 212-213, provided a photo and brief account for French Guiana. 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. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 242-243, provided an account of Pristimantis cf marmoratus. MacCulloch and Lathrop, 2009, R. Ontario Mus. Contrib. Sci., 4: 16, commented on specimens from Mount Ayanganna, Guyana. See account for Surinam population by Ouboter and Jairam, 2012, Amph. Suriname: 310-313.See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 388-389, for brief account and records for Guyana. Kok, Dezfoulian, Means, Fouquet, and Barrio-Amorós, 2018, Eur. J. Taxon., 397: 1–30, amended the diagnosis and reported on its advertisement call, breeding ecology, and phylogenetic relationships and suggested that records from French Guiana represent at least two unnamed species and records from Surinam and from the slopes of Marahuaka-tepui, Amazonas, Venezuela, are misidentification.
