Comment

In the Eleutherodactylus discoidalis group of Lynch, 1989, Milwaukee Public Mus. Contrib. Biol. Geol., 79: 1–25, who provided an account. See account by Cei, 1980, Monit. Zool. Ital., N.S., Monogr., 2: 311–312. In the Eleutherodactylus (Eleutherodactylus) conspicillatus series, Eleutherodactylus discoidalis group of Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 223. See comment under Eleutherodactylus cruralis with which it has been confused. Köhler, 2000, Bonn. Zool. Monogr., 48: 114–115, provided brief comments. Heinicke, Duellman, and Hedges, 2007, Proc. Natl. Acad. Sci. USA, 104: 10092–10097, removed this species from nominal Eleutherodactylus but did not provide a new generic name. Padial, Köhler, Muñoz-Saravia, and De la Riva, 2008, Zool. J. Linn. Soc., 152: 353–365, reported on acoustic variation among members of the "Eleutherodactylus" discoidalis group. See account by Padial, Chaparro, and De la Riva, 2008, Zool. J. Linn. Soc., 152: 753–755. Akmentins, 2011, J. Nat. Hist., London, 45: 1789–1799, reported on the vocal repertoire. Ferro, Taffarel, Cardozo, Grosso, Puig, Suárez, and Akmentins, 2016, Comp. Cytogenet., 10: 141–156, reported on chromosome morphology of the Argentina populations. Akmentins, Boullhesen, García, and Martínez, 2022, S. Am. J. Herpetol., 25: 28–33, transferred the populations from Jujuy and Salta, Argentina, to Oreobates berdemenos on the basis of call structure. They did not report on the calls from the type locality of Oreobates discoidalis (Tucumán) or from populations assigned to this species from Bolivia. Both now require confirmation as does the taxonomic status of Oreobates discoidalis itself.
