Endemic ranges Most member species are endemic to southwestern China, with at least two species in northern Vietnam (O. sterlingae and O. adelphos) and some possibly extending into adjacent Laos. There is also a population in Arunachal Pradesh (Northeast India) that has not yet been assigned to a species, although it may rather be assigned to the genus Scutiger.
Many Oreolalax species are endemic to highly restricted geographical areas in the Eastern Himalayas, especially in Sichuan, China. The ranges often overlap with those of Scutiger species.
