Trachycephalus dibernardoi Kwet and Solé, 2008, Zootaxa, 1947: 54. Holotype: MCP 2422, by original designation. Type locality: "'Centro de Pesquisas e Conservação da Natureza' (CPCN) Pró Mata (about 950 m a.s.l.), 29° 30´S, 50° 10´W, municipality of São Francisco de Paula, state of Rio Grande do Sul, Brazil".

English Names

None noted.


Araucaria Plateau in extreme north-eastern and northern Rio Grande do Sul (municipalities of São Francisco de Paula, 950 m elevation, and Machadinho, 760 m a.s.l.) and western Santa Catarina (municipality Seara, 550 m elevation) into northeast-central Paraná; also known from El Soberbio (department Guaraní, 190 m elevation) in the Argentinian province Misiones. Expected to have much wider range, presumably extending into the adjacent regions of northern and northeastern Rio Grande do Sul, Santa Catarina, and Paraná, Brazil, as well as Misiones Province, Argentina, and likely Paraguay.

Geographic Occurrence

Natural Resident: Argentina, Brazil

Likely/Controversially Present: Paraguay


Confused with Trachycephalus imitatrix prior to its naming. Conte, Nomura, Machado, Kwet, Lingnau, and Rossa-Feres, 2010, Biota Neotrop., São Paulo, 10: 201–224, provided a new record from Telêmaco Borba, Paraná. and discussed natural history and the advertisement call. Forti, Foratto, Márquez, Pereira, and Toledo, 2018, PeerJ, 6(e4813): 1–19, characterized the advertisement call. Blotto, Lyra, Cardoso, Rodrigues, Dias, Marciano, Vechio, Orrico, Brandão, Assis, Lantyer-Silva, Rutherford, Gagliardi-Urrutia, Solé, Baldo, Nunes, Cajade, Torres, Grant, Jungfer, Silva, Haddad, and Faivovich, 2021, Cladistics, 37: 36–72, suggested that the taxonomic status of this  taxon relative to Trachycephalus imitatrix requires additional study. Subsequently, Provete, Garey, Picheli, Mello, Gonçalves, Conte, and Rossa-Feres, 2021, J. Herpetol., 55: 237–252, reported that the advertisement calls and tadpoles of this species and Trachycephalus imitatrix differ.
