Zidok Cochran Frog (Vitreorana oyampiensis [no longer recognized]: (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 47).

Headwater Cochran Frog (Cochranella ametarsia [no longer recognized]: Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 46).

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 central Amazonia and west to extreme western Amazonas.

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.
