distribution

Distribution and natural history. Currently, Megophrys nanglingensis sp. nov. is known from Nanling Nature Reserve and the neighboring Mangshan Nature Reserve (between elevations of 1000 - 1300 m), together with Mt. Qiyun (between elevations of 690 - 1400 m). It inhabits streams in bamboo forests. Males are frequently heard calling during August and December. Tadpoles could be found in this period. Megophrys nanlingensis sp. nov. is sympatric with M. mangshanensis and M. popei in Nanling Nature Reserve and the neighboring Mangshan Nature Reserve.
