Adelophryne Hoogmoed and Lescure, 1984
Adelophryne Hoogmoed and Lescure, 1984, Zool. Meded., Leiden, 58: 92. Type species: Adelophryne adiastola Hoogmoed and Lescure, 1984, by original designation.
Shield Frogs (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 70).
Northern South America east of the Andes (roughly, the Guiana Shield).
This nominal genus shows variation in the number of phalanges in the 4th digit: 2 or 3. In part, this character is shared with Euparkerella, Phyllonastes, Phyzelaphryne, and Brachycephalus. Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 197-198, suggested this to be synapomorphic, but also (p. 199) noted a character that would ally Adelophryne with Phyzelaphryne and the Eleutherodactylus diastema group. Silva, Campos, and Sebben, 2007, Zootaxa, 1422: 59-68, suggested that this might be mistaken although they presented no evidence to reject the topology. Hedges, Duellman, and Heinicke, 2008, Zootaxa, 1737: 93, placed Adelophryne and Phyzelaphryne in Phyzelaphryninae and rejected a close relationship to Euparkerella, Phyllonastes, and Brachycephalus. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, confirmed the sister-taxon relationship of Adelophryne and Phyzelaphryne. See comment under Phyllonastes. See Hoogmoed, Borges, and Cascon, 1994, Zool. Meded., Leiden, 68: 271-300, for discussion and key to the species. Fouquet, Loebmann, Castroviejo-Fisher, Padial, Orrico, Lyra, Roberto, Kok, Haddad, and Rodrigues, 2012, Mol. Phylogenet. Evol., 65: 547-561, provided a molecular phylogenetic analysis and suggested that many species remain to be named in this clade. Padial, Grant, and Frost, 2014, Zootaxa, 3825: 60, found this taxon to be in Phyzelaphryninae, but only dubiously distinct from Phyzelaphryne.
