Removed from the synonymy of Philautus by Dubois, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 257, where it had been placed by Smith, 1931, Bull. Raffles Mus., 5: 19. See comment under Theloderma moloch. Wilkinson, Drewes, and Tatum, 2002, Mol. Phylogenet. Evol., 24: 265-273, Grosjean, Delorme, Dubois, and Ohler, 2008, J. Zool. Syst. Evol. Res., 46: 169-176, and Li, Che, Bain, Zhao, and Zhang, 2008, Mol. Phylogenet. Evol., 48: 302-312, and Yu, Rao, Zhang, and Yang, 2009, Mol. Phylogenet. Evol., 50: 571-579, suggested on the basis of molecular evidence that Nyctixalus is the sister taxon of Theloderma. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, confirmed this placement in their study of Genbank sequences. Li, Li, Klaus, Rao, Hillis, and Zhang, 2013, Proc. Natl. Acad. Sci. USA, 110: 34413446, further confirmed this placement.
