Range Description

This species is known from five locations in Thailand: Tasan (in Chumphon Province); Mamoh and Khlong Naka Wildlife Sanctuary (in Renong Province); Khlong Saeng National Park (in Surat Thani Province); and Khaolak Lamru National Park (in Phagnga Province), near the Isthmus of Kra. One recent record is from Tong Pha Phume in Kanchanaburi Province further north in western Thailand (Wichase Khonsue pers. comm.). Possible records from Phuket (P. van Dijk pers. comm.) remain to be verified. It probably occurs in southern Tenasserim (Myanmar), but this has not yet been confirmed. It has been recorded at around 1,000m asl.

Habitat and Ecology

It lives in primary rainforest near streams. It has also been observed on near-vertical bedrock in the spray zone of rainforest waterfalls. It presumably breeds by direct development, like other members of its genus.

Population

It is an uncommon species.

Population Trend
