Three new species of the microhylid frog genus Choerophryne (Amphibia, Anura, Microhylidae) from Papua New Guinea

摘要

We describe three new species of the microhylid frog genus Choerophryne from the mountains and foothills of southern and northeastern Papua New Guinea. All three species lack elongated snouts and all are arboreal calling from elevated perch sites between ~1 and 10 m above the forest floor. Advertisement calls and habitat preferences are described for each species. Descriptions of these three frogs brings the total number of Choerophryne recognized to 34 but numerous additional species undoubtedly remain to be discovered in poorly-surveyed mountainous regions of New Guinea.
