Oxydactyla Van Kampen, 1913
Oxydactyla Van Kampen, 1913, Nova Guinea, 9: 464. Type species: Oxydactyla brevicrus Van Kampen, 1913, by monotypy.
Removed from the synonymy of Sphenophryne by Zweifel, 2000, Bull. Am. Mus. Nat. Hist., 253: 74, where it had been placed by Parker, 1934, Monogr. Frogs Fam. Microhylidae: 152; Loveridge, 1948, Bull. Mus. Comp. Zool., 101: 422. Revision in Zweifel, 2000, Bull. Am. Mus. Nat. Hist., 253: 1-130. Köhler and Günther, 2008, Mol. Phylogenet. Evol., 47: 353-365, suggested on the basis of molecular evidence that Oxydactyla is part of a monophyletic group containing Liophryne rhododactyla, Liophryne dentata, and Sphenophryne. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, came to a different conclusion; see comment under Liophryne.
