Barrio-Amorós, 1999 "1998", Acta Biol. Venezuelica, 18: 58, commented on the Venezuelan distribution. Zimmerman, 1983, Herpetologica, 39: 235–246, and Zimmerman and Bogart, 1984, Acta Amazonica, 14: 473–520, reported on vocalization. Señaris, Molina, and Villarreal, 2003, Herpetol. Rev., 34: 260, provided a record for Amazonas, Venezuela. Zimmerman and Rodrigues, 1990, in Gentry (ed.), Four Neotropical Rainforests: 426–454, provided the first central Brazilan Amazonia record for this species, near Manaus. Kok and Kalamandeen, 2008, Intr. Taxon. Amph. Kaieteur Natl. Park: 232–233, provided an account, reported the species from Kaieteur National Park, Guyana (although noting some differences), and questioned the identity of the Manaus, Brazil, specimens. Señaris, Lampo, Rojas-Runjaic, and Barrio-Amorós, 2014, Guía Ilust. Anf. Parque Nac. Canaima: 232–233, provided a photograph and a brief account for the Parque Nacional de Canaima, Venezuela. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 105, for comments on range and literature. For identification of larvae in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262, although who Fouquet, Leblanc, Fabre, Rodrigues, Menin, Courtois, Dewynter, Hölting, Ernst, Peloso, and Kok, 2021, Zool. Anz., 293: 46–73, who rediagnosed the species, discussed osteology, external morphology, advertisement call, range, and natural history, implied that all records substantially distant from the type locality are based on misidentifications or unnamed species.
