Abstract
Based on morphological, anatomical, ecological, ethological, and molecular traits, two new genera of microhylid frogs from mainland New Guinea are described. Metamagnusia gen. n. includes two species, M. marani sp. n., the type species found in the Wondiwoi Mountains at the base of the Wandammen Peninsula (Papua Province, Indonesia), and M. slateri (Loveridge, 1955) comb. n., from eastern New Guinea (Papua New Guinea). The second new genus, Pseudocallulops gen. n., also includes two species, P. eurydactylus (Zweifel, 1972) comb. n. from the Fakfak Mountains on the Bomberai Peninsula (Papua Province, Indonesia), and P. pullifer (Gunther, 2006) comb. n., which is designated as the type species and which occurs in the Wondiwoi Mountains at the base of the Wandammen Peninsula. Both new genera belong to the group of asterophryine genera with a symphignathine state of the maxillary bones. Metamagnusia gen. n. is most closely related to the genus Asterophrys, while Pseudocallulops gen. n. forms a sister-clade of the taxa Asterophrys + Metamagnusia. The new genera are erected to recognize their differences in fundamental traits from the presently recognized genera. Another goal was to dissolve polyphyletic taxa and to avoid creation of paraphyletic taxa within the symphignathine genera of the Australopapuan microhylids. (© 2009 WILEY-VCH Verlag GmbH & Co.
