Comment

Duellman, 1978, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 65: 188–189, provided a brief account. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 74, provided a brief account for the Iquitos region of northeastern Peru. Possible occurrence in Bolivia mentioned by De la Riva, Köhler, Lötters, and Reichle, 2000, Rev. Esp. Herpetol., 14: 51. Gonzales-Álvarez and Reichle, 2004, Rev. Boliviana Ecol. Conserv. Ambiental, 15: 93–96, provided a record for San Sebastián, Bolivia. Peloso and Sturaro, 2008, Zootaxa, 1947: 40, suggested that because the holotype is in poor condition and the type locality vague that application of this name to a particular living populations may be problematic. Santana, Sant’Anna, São Pedro, and Feio, 2009, S. Am. J. Herpetol., 4: 226–228, described the advertisement call. Morales and McDiarmid, 2009, Biotempo, Lima, 9: 74, suggested that the specimens reported from Santa Cecilia, Ecuador, and Iquitos, Peru, show distinctive characteristics that may suggest that these populations are not referable to Chiasmocleis bassleri. 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. Bernarde, Machado, and Turci, 2011, Biota Neotrop., 11: 117–144, reported specimens from Reserva Extrativista Riozinho da Liberdade, Acre, Brazil. Rodrigues, Noronha, Lima, and Rosa, 2011, Check List, 7: 846-848, provided a range extension and a spot map. Peloso, Sturaro, Forlani, Gaucher, Motta, and Wheeler, 2014, Bull. Am. Mus. Nat. Hist., 386: 37–42, provided an account and placed this species in the Chiasmocleis bassleri clade. 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. Gómez-Murillo and Arellano-Martín, 2020, Bol. Asoc. Herpetol. Esp., 31: 80–81, provided a record from Villa Tunari, Provincia Chapare, Departamento de Cochabamba, Bolivia, and provided a polygon map for the range of the species. Gagliardi-Urrutia, García Dávila, Jaramillo-Martinez, Rojas-Padilla, Rios-Alva, Aguilar-Manihuari, Pérez-Peña, Castroviejo-Fisher, Simões, Estivals, Guillen Huaman, Castro Ruiz, Angulo Chávez, Mariac, Duponchelle, and Renno, 2022, Anf. Loreto: 160–161, provided a brief account, photograph, dot map, and genetic barcode for Loreto, Peru.
