Physalaemus albonotatus (Steindachner, 1864)

Class: Amphibia > Order: Anura > Family: Leptodactylidae > Subfamily: Leiuperinae > Genus: Physalaemus > Species: Physalaemus albonotatus

Physolaemus albonotatus Jan, 1857, Cenni Mus. Civ. Milano: 52. Type(s): MSNM. Type locality: Not stated. Nomen nudum, likely in this synonymy (DRF), attributed to Tschudi and Fitzinger, presumably based on jar label names.

Leiuperus albonotatus Steindachner, 1864, Verh. Zool. Bot. Ges. Wien, 14: 275. Type(s): Not designated; presumably originally NHMW but not noted in recent type lists. Type locality: "Caiçara, [Caceres,] Matogrosso, Pará" (Pará, in error), Brazil. Restricted to "Caiçara, Cáceres, Mato Grosso", Brazil by Bokermann, 1966, Lista Anot. Local. Tipo Anf. Brasil.: 70, who noted that some of the original type material is referable to Physalaemus ephippifer.

In the Physalaemus cuvieri group of Nascimento, Caramaschi, and Cruz, 2005, Arq. Mus. Nac., Rio de Janeiro, 63: 308. Physalaemus albonotatus is a sibling species of Physalaemus cuvieri with which it has been commonly confused; see Barrio, 1965, Physis, Buenos Aires, 25: 421–448. Márquez, De la Riva, and Bosch, 1995, J. Zool., London, 237: 313–336, reported on vocalization in Bolivia. Köhler, 2000, Bonn. Zool. Monogr., 48: 138–139, provided a brief account. See note by Herrera and Voglino, 2002, Cuad. Herpetol., 16: 91, on range in Argentina. Kehr, Schaefer, and Duré, 2004, J. Herpetol., 38: 145–148, reported on larval morphology. Brusquetti and Lavilla, 2006, Cuad. Herpetol., 20: 17, briefly discussed the range in Paraguay.Jansen, Bloch, Schulze, and Pfenninger, 2011, Zool. Scripta, 40: 567–583, noted genetic variation within this species in Bolivia. Köhler, John, and Böhme, 2006, Salamandra, 42: 21–27, provided a record for the Yungas de La Paz region of La Paz Province, Bolivia. Weiler, Núñez, Airaldi, Lavilla, Peris, and Baldo, 2013, Anf. Paraguay: 101, provided a brief account, image, and dot map for Paraguay. In the Physalaemus cuvieri clade, Physalaemus cuvieri species group, of Lourenço, Targueta, Baldo, Nascimento, Garcia, Andrade, Haddad, and Recco-Pimentel, 2015, Mol. Phylogenet. Evol., 92: 204–216, who also noted that cryptic species exist under this name. Schulze, Jansen, and Köhler, 2015, Zootaxa, 4016: 31–34, described, diagnosed, and pictured the larva of their Physalaemus cf. albonotatus, treated so in recognition of the lack of DNA sequence information from the type locality. Borges, Oliveira, Santos, Souza, Morais, Maciel, and Oliveira, 2019, Herpetol. Notes, 21: 901–904, reported a record from Emas National Park, Municipality of Mineiros, western Goiás, Brazil, and mapped the species' range in South America. Hepp and Pombal, 2020, Zootaxa, 4725: 1–106, discussed this species as part of a genus-wide discussion of bioacoustical traits among the species.
