Comment

In the Eleutherodactylus (Eleutherodactylus) conspicillatus series, Eleutherodactylus conspicillatus group according to Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 234. Reviewed by Lynch, 1980, Am. Mus. Novit., 2696: 17, who provided a synonymy. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 62–63, provided a brief account for the Iquitos region of northeastern Peru as Eleutherodactylus vilarsi. See brief account by Lynch, 1994, Rev. Acad. Colomb. Cienc. Exact. Fis. Nat., 19: 187–193. See comments regarding distribution of Venezuelan population by Gorzula and Señaris, 1999 "1998", Scient. Guaianae, 8: 54. Discussed and redescribed by Barrio-Amorós and Molina, 2006, Zootaxa, 1302: 1–20. In the Pristimantis conspicillatus species group of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 120, and Padial, Grant, and Frost, 2014, Zootaxa, 3825: 125. Heyer and Barrio-Amorós, 2009, Proc. Biol. Soc. Washington, 122: 282–291, described the advertisement call. See Duellman and Lehr, 2009, Terrest.-breeding Frogs in Peru: 253–254, for brief account. Moraes, Almeida, Fraga, Rojas-Zamora, Pirani, Silva, Carvalho, Gordo, and Werneck, 2017, ZooKeys, 715: 103–159, reported on specimens of Pristimantis cf vilarsi from the Serra da Mocidade, state of Roraima, northern Brazil. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 129, for comments on range and literature. Araujo de Oliveira, Silva, Guimarães, Penhacek, Martínez, Rodrigues, Santana, and Hernández-Ruz, 2020, PLoS One, 15 (3: e0229971): 1–28, reported on the advertisement call. In the Pristimantis conspicillatus group, Pristimantis vilarsi clade of Fouquet, Réjaud, Rodrigues, Ron, Chaparro, Osorno-Muñoz, Werneck, Hrbek, Lima, Camacho-Badani, Jaramillo-Martinez, and Chave, 2022, Syst.
