Description of two new taxa of the ceratobatrachid genus Platymantis from western New Guinea (Amphibia, Anura)

Two new taxa of the ceratobatrachid genus Platymantis are described from western New Guinea on the basis of bioacoustic, morphological, ecological and biochemical studies. One of these, described as new species, is known only from in the Fakfak Mountains (Bomberai Peninsula) and the other, described as new subspecies, from Yapen Island. Their nearest relatives appear to be P. batantae Zweifel, 1969, and P. cryptotis Günther, 1999 respectively. Besides data on the new taxa, some morphological, bioacoustic and molecular data are given for P. papuensis Meyer, 1875 from the type locality Biak Island.
