Comment

Key and systematic discussion provided by Blum and Menzies, 1989 "1988", Alytes, 7: 125-163. Removed from the synonymy of Asterophrys by Zweifel, 1972, Bull. Am. Mus. Nat. Hist., 148: 426, where it had been placed by Parker, 1934, Monogr. Frogs Fam. Microhylidae: 58. Kraus and Allison, 2002, Herpetologica, 58: 56, noted that recognition of Xenobatrachus may render Xenorhina paraphyletic. See Blum and Menzies, 1989 "1988", Alytes, 7: 125-163, for discussion of former Xenobatrachus. Menzies, 2006, Frogs New Guinea & Solomon Is.: 255-271, discussed the difficulty in separating former Xenorhina from Xenobatrachus, abandoned the Xenobatrachus rostratus group as undiagnosable, and provided brief accounts for the species. Köhler and Günther, 2008, Mol. Phylogenet. Evol., 47: 353-365, on the basis of molecular evidence regarded Xenobatrachus as phylogenetically imbedded within Xenorhina and supported the synonymy. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, suggested that Xenorhina is polyphyletic, with Xenorhina obesa (a former member of Xenobatrachus) falling far from the remainder of their exemplars (composed of species formerly assigned to both Xenobatrachus and Xenorhina) of this genus.
