Abstract
A new species of frog with a prominent rostral spike is described from the Sepik Basin, northern lowlands of Papua New Guinea. The new species is most similar to Litoria prora (Menzies) and L. humboldtorum Gunther but differs from those species in its smaller size, reduced dermal lappets on the limbs, and unique advertisement call. It is the sixth species of Australopapuan hylid frog known to possess a dermal projection on the snout.References
