Comment

Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 266–267, provided a photo and brief account for French Guiana. Zweifel and Myers, 1989, Am. Mus. Novit., 2947: 1–24, reported the species for Venezuela. Barrio-Amorós and Schargel, 2003, Herpetol. Rev., 34: 380, provided an additional Venezuelan record and commented on the distribution. Fouquet, Gilles, Vences, Marty, Blanc, and Gemmell, 2007, PLoS One, 10 (e1109): 1–10, provided molecular evidence that this is a species complex. Rodrigues, Menin, Lima, and Mokross, 2008, Zootaxa, 1680: 55–58, reported on vocalizations and tadpole morphology. Bernardo, Matiazzi, and Guerra-Fuentes, 2012, Check List, 8: 152-154, provided a number of new records from Pará, Brazil, and provided a spot map for nominal Chiasmocleis jimi. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 272–273. In the Chiasmocleis hudsoni clade of Peloso, Sturaro, Forlani, Gaucher, Motta, and Wheeler, 2014, Bull. Am. Mus. Nat. Hist., 386: 20, who (p. 46–51) provided an account and noted a record for Leticia, Amazonas, Colombia. Costa-Campos, Sousa, and Menin, 2019, Herpetol. Notes, 12: 405–408, reported the species from Serra do Navio municipality, State of Amapá, Brazil. de Sá, Tonini, van Huss, Long, Cuddy, Forlani, Peloso, Zaher, and Haddad, 2018 "2019", Mol. Phylogenet. Evol., 130: 203, recognized Chiasmocleis jimi as distinct, but having not sampled the type locality and recognizing three lineages, of which only two have names, within nominal Chiasmocleis hudsonicus the synonymy was retained by Cassundé, Sturaro, Maciel, Prudente, Sarmento, and Peloso, 2022, Bol. Mus. Parense Emilio Goeldi, Cienc. Nat., 17: 455–456. See Barrio-Amorós, Rojas-Runjaic, and Señaris, 2019, Amph. Rept. Conserv., 13 (1: e180): 101, for comments on range and literature. 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: 96–97, detailed larval and metamorph morphology and natural history.
