Comment

Zweifel and Myers, 1989, Am. Mus. Novit., 2947: 1-16, have posited that the name Ctenophryne geayi actually represent two species (northern and southern populations). Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 190–191, provided a brief account including characterization of call. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 75–76, provided a brief account for the Iquitos region of northeastern Peru. Duellman, 1997, Sci. Pap. Nat. Hist. Mus. Univ. Kansas, 2: 29–30, commented on the natural history of the southeastern Venezuela population. De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 58, and Köhler, 2000, Bonn. Zool. Monogr., 48: 69, consider this species possibly to occur in Bolivia. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 270-271, provided a photo and brief account for French Guiana. Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 56-57, commented on the Venezuelan distribution. Zimmerman and Rodrigues, 1990, in Gentry (ed.), Four Neotropical Rainforests: 426-454, provided the first central Brazilan Amazonia record for this species, near Manaus. França and Venâncio, 2010, Biotemas, 23: 71–84, provided a record for the municipality of Boca do Acre, Amazonas, with a brief discussion of the range. Duellman, 2005, Cusco Amazonico: 297–299, provided an account (adult and larval morphology, description of the call, life history). Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 276-277. Freitas, Dias, Farias, Oliveira e Sousa, Vieira, Moura, and Uhlig, 2014, Check List, 10: 585–587, provided a record for the state of Maranhao, Brazil, and discussed the range. Gonzales-Álvarez and Reichle, 2004, Rev. Boliviana Ecol. Conserv. Ambiental, 15: 93–96, provided a record for Chivé, Bolivia. See Barrio-Amorós, Rojas-Runjaic, and Señaris Vasquez, 2019, Amph. Rept. Conserv., 13 (1: e180): 102, for comments on range and literature. For identification of larvae in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. See brief account for the Manu region, Peru, by Villacampa-Ortega, Serrano-Rojas, and Whitworth, 2017, Amph. Manu Learning Cent.: 248–249. Metcalf, Marsh, Torres Pacaya, Graham, and Gunnels, 2020, Herpetol. Notes, 13: 753–767, reported the species from the Santa Cruz Forest Reserve, Loreto, northeastern Peru. Tavares-Pinheiro, Figueiredo, and Costa-Campos, 2021, Herpetol. Notes, 14: 883–886, provided a dot map for the species and a record from southern Amapá, Brazil. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 96–130, reported on distribution, literature, and conservation status for Amapá, Brazil. Schiesari, Rossa-Feres, Menin, and Hödl, 2022, Zootaxa, 5223: 98–99, detailed larval morphology and natural history.
