Abstract:

Choerophryne burtoni sp. nov. is described from lower-montane rainforest in the Kikori Integrated Conservation and Development Project area, Southern Highlands Province, Papua New Guinea. It is distinguished from congeners by a combination of moderately small size (three males 12.1-12.4 mm SV), reduced snout overhang and its unique advertisement call. The call is a series of 1-6 notes, each containing 9-15 pulses and produced at a rate of 1.5 notes/s. The dominant frequency is 4590-4800 Hz. Males called from hidden sites in curled leaves about 0.2-1.0 m above the forest floor during and after heavy rain.
