This species is known only from two sites in Peninsular Malaysia: Sungai Lembing logging camp (3° 52.26” N, 103° 3’.13” E), in Pahang Province, at 255m asl; and Gunung Benom in the western part of Pahang Province (Grismer, 2006). The elevation of the Gunung Benom records is not recorded, though it is likely to be higher than Sungai Lembing logging camp. The species presumably occurs more widely, especially in locations between the currently known sites.
Habitat and Ecology
This species is associated with streams in closed-canopy hill dipterocarp forest (Grismer, 2006). These toads perch no higher than two metres above the ground on leaves overhanging the streambed or on the tops of large rocks along the edge of the stream (Grismer, 2006). The ability of this species to adapt to modification of its forest habitat is not known.
It is very common at Sugai Lembing, and probably locally common at Gunung Benom.
There is currently no direct information on threats to this species, but it is very likely to occur in places where its forest habitat is being lost to logging and agricultural expansion (indeed, Sugai Lembing was a logging camp).
Gunung Benom is in a protected area. Surveys are needed to determine its geographic range, abundance, ecological requirements, threats and conservation needs.
