Geographic Occurrence

Natural Resident: Brazil

Endemic: Brazil


Placed in the Eleutherodactylus fitzingeri group by Lynch, 1976, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 61: 10; subsequently not included in the group because of its obscure relationships (see Lynch and Myers, 1983, Bull. Am. Mus. Nat. Hist., 175: 481-572). Unassigned to formal series or species group of Eleutherodactylus by Lynch and Duellman, 1997, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 23: 221. Pimenta and Silvano, 2002, Herpetol. Rev., 33: 144, provided new localities in Brazil. In the Ischnocnema lactea species series of Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 27. Canedo and Haddad, 2012, Mol. Phylogenet. Evol., 65: 610-620, suggested on the basis of molecular evidence that this species is not an Eleutherodactylus or Ischnocnema, but rather of uncertain position, likely close to Noblella + Barycholos within Holoadeninae. Dias, Mira-Mendes, Souza-Costa, Juncá, and Solé, 2017, ZooKeys, 677: 151–159, reported on vocalization and range. Juncá, 2006, Biota Neotrop., 6: 1–17, briefly summarized the presence of this species in the Serra da Jibóia region, Bahia, Brazil, and its habitat.
