Comment

Removed from the synonymy of Eleutherodactylus and redelimited on the basis of molecular evidence by Heinicke, Duellman, and Hedges, 2007, Proc. Natl. Acad. Sci. USA, 104: 10092-10097, and Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 1–182, where it had been placed by Caramaschi and Canedo, 2006, Zootaxa, 1116: 43. See comment under Brachycephalidae. Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 1–182, defined species series noted in the comments; these are also summarized by Padial, Grant, and Frost, 2014, Zootaxa, 3825: 121, who reported on the phylogenetics of the group, as did Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543–583, and Canedo and Haddad, 2012, Mol. Phylogenet. Evol., 65: 610–620, who both confirmed the sister-taxon relationship with Brachycephalus
