Comment

In the Eleutherodactylus unistrigatus group, Eleutherodactylus lacrimosus assemblage, according to Heyer and Hardy, 1991, Proc. Biol. Soc. Washington, 104: 444. In the Eleutherodactylus (Eleutherodactylus) martinicensis series, Eleutherodactylus unistrigatus group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 230. Mueses-Cisneros, 2005, Caldasia, 27: 236, provided records for Putumayo, Colombia. In the Pristimantis lacrimosus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 123, and of Padial, Grant, and Frost, 2014, Zootaxa, 3825: 126. See photograph, map, description of geographic range and habitat, and conservation status (as Eleutherodactylus petersorum) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 367. See note by Guayasamin and Funk, 2009, Zootaxa, 2220: 41–66, on this species (i.e., Pristimantis cf. petersi) at the Yanayacu Biological Station, Napo, Ecuador. Brito-M., Batallas-Revelo, and Yánez-Muñoz, 2017, Neotropical Biodiversity, 3: 125–156, provided a record from Morona Santiago, Ecuador and brief natural history notes. Batallas-Revelo and Brito-M., 2016, Rev. Mexicana Biodiversidad, 87: 1292–1300, reported on vocalizations from Sangay National Park, southeastern Ecuador. Coloma and Duellman, 2025, Amph. Ecuador. Vol. 3: 307–308, provided an account with photographs which summarized morphological identification, (the tentative nature of its) systematics, natural history, distribution (including a dot map for Ecuador), conservation, and also (pp. 480–481) described the advertisement call.
