Distribution

Known from two localities in the Amazonian lowlands (below 300 m elevation) of Orellana Province, eastern Ecuador; Amazonas, Colombia, and one locality in Amazonian Peru (Loreto) and Provincia Roman, Departamento Pando, Bolivia; southern Guyana, eastern Surinam, French Guiana and in Brazil from Roraima south to extreme western Amazonas and the municipalities of Cotriguaçu and Sinop, Mato Grosso, and east to Amapá and central Pará, Brazil. 

Comment

In the Cochranella ocellata group, according to Ruiz-Carranza and Lynch, 1991, Lozania, 57: 1-30. Placed in the Cochranella spinosa group by Savage, 2002, Amph. Rept. Costa Rica: 365. See comment under Cochranella resplendens. Guayasamin, Castroviejo-Fisher, Trueb, Ayarzagüena, Rada, and Vilà, 2009, Zootaxa, 2100: 39, suggested that this is a likely senior synonym of Vitreorana oyampiensis. Cisneros-Heredia, 2013, Avanc. Cienc. Ingen., Quito, Secc. B,, 5: B1, made the formal synonymy. Moraes, Almeida, Fraga, Rojas-Zamora, Pirani, Silva, Carvalho, Gordo, and Werneck, 2017, ZooKeys, 715: 103–159, reported on specimens from the Serra da Mocidade, state of Roraima, northern Brazil. Muñoz-Saravia and Aguayo-Vedia, 2009, Cuad. Herpetol., 23: 97–99, provided a record from the Provincia Roman, Departamento Pando, Bolivia (as Vitreorana oyampiensis).  Fouquet, Vidal, and Dewynter, 2019, Zoosystema, 41: 366, were dubious of the synonymy of Vitreorana oyampiensis. For identification of larvae (as Centrolenella oyampiensis) in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. Guayasamin, Cisneros-Heredia, McDiarmid, Peña, and Hutter, 2020, Diversity, 12 (222): 245–250, provided a detailed account, including adult and larval morphology, advertisement call, relationships, natural history, and conservation status. Penhacek, Anjos, Araujo de Oliveira, Hernández-Ruz, Rodrigues, Guerra, and Rodrigues, 2020, Caldasia, 42: 171–180, reported on localities in Mato Grosso, Brazil, inferred from molecular and acoustic evidence. Costa-Campos, Figueiredo, Lima, and Lima, 2020, Herpetol. Notes, 13: 733–737, provided new records for Amapá, Brazil, and provided a dot map of the distribution.
