This species is so far known only from Peta Visitor Centre in Endau-Rompin National Park, Johor Province, Peninsular Malaysia at 46m asl (Grismer, 2007). This species presumably occurs more widely, beyond the confines of Endau-Rompin National Park.
Habitat and Ecology
The only record so far of this species was of individuals heard calling from a swampy area centered on a slow-moving, shallow stream beneath a closed-canopy portion of lowland forest. All individuals were collected during the early evening following a brief period of afternoon precipitation. They were seated no higher than 0.5 m above the ground on dead vegetation along the streambed.
There is no information on its abundance. It is so far known from only three specimens (Grismer, 2006).
Its only known location is in a well-protected location. However, if it is occurs more widely, as is very likely, it will most likely be found to be present in places where its habitat is at risk from logging and agricultural expansion (especially oil palm plantations).
It occurs in the Endau-Rompin National Park. Surveys are needed to determine its geographic range, abundance, ecological requirements, threats and conservation needs.
