From the IUCN Red List Species Account:


Range Description

This species is so far known only from Sungai Semawak, in Endau-Rompin National Park, Johor Province, Peninsular Malaysia at 46m asl (Grismer, 2006). The type locality is 5km west of the Endau-Rompin National Park visitor centre at Peta (Grismer, 2006). This species presumably occurs more widely, beyond the confines of Endau-Rompin National Park.

Habitat and Ecology

All individuals were collected from the same small, rocky stream (Sungai Semawak) which runs through a closed-canopy portion of lowland forest (Grismer, 2006). They were found at night following periods of afternoon precipitation, and were perched no higher than one metre above the ground on small leaves overhanging the streambed (Grismer, 2006). Its breeding has not been observed (Grismer, 2006), but it is presumably by larval development in streams.


There is no information on its abundance. It is so far known from only four specimens (Grismer, 2006).

Population Trend


Major Threats

Its only known location is in a well-protected location. However, it is occurs more widely, it could be found to be present in places where its habitat is at risk from logging and agricultural expansion (especially oil palm plantations).

Conservation Actions

It occurs in the Endau-Rompin National Park. Surveys are needed to determine its geographic range, abundance, ecological requirements, threats and conservation needs.
