Comment

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. Zimmerman and Bogart, 1984, Acta Amazonica, 14: 473–520, reported on vocalization. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 268-269, provided a photo and brief account for French Guiana, and noted that this species may be conspecific with Chiasmocleis ventrimaculata. Zimmerman and Rodrigues, 1990, in Gentry (ed.), Four Neotropical Rainforests: 426–454, provided the first central Brazilan Amazonia record for this species, near Manaus. Peloso and Sturaro, 2008, Zootaxa, 1947: 50, reported considerable morphological variation among populations suggestive of cryptic species. See account for Suriname population by Ouboter and Jairam, 2012, Amph. Suriname: 274–275. In the Chiasmocleis shudikarensis clade of Peloso, Sturaro, Forlani, Gaucher, Motta, and Wheeler, 2014, Bull. Am. Mus. Nat. Hist., 386: 20, who (pp. 52–55) provided an account. For identification of larvae in central Amazonia, Brazil, see Hero, 1990, Amazoniana, 11: 201–262. 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: 97–98, detailed larval morphology and natural history.
