See account by Brown and Alcala, 1994, Proc. California Acad. Sci., Ser. 4, 48: 185–220 (as Philautus emembranatus, and who considered it to be in the Philautus surdus group). Brown, Alcala, and Brown, 1998, J. Herpetol., 32: 131–132, discussed the nomenclature of the species, removing the senior name from the synonymy of Platymantis guentheri, where it had been placed by Inger, 1954, Fieldiana, Zool., 33: 362.
