Two new microhylid frogs in the genera Choerophryne and Oreophryne are described from the Foja Mountains in Papua Province of Indonesia. Both are small species (males 15.9 – 18.5 mm snout-urostyle length SUL and 21.3 – 22.9 mm SUL respectively) that call from elevated positions on foliage in primary lower montane rainforest. The new Choerophryne species can be distinguished from all congeners by, among other characters, a unique advertisement call consisting of an unpulsed (or very finely pulsed) peeping note lasting 0.29 – 0.37 seconds. The new Oreophryne species belongs to a group that has a cartilaginous connection between the procoracoid and scapula and rattling advertisement calls. Its advertisement call is a loud rattle lasting 1.2 – 1.5 s with a note repetition rate of 11.3 – 11.7 notes per second.
