From the IUCN Red List Species Account:


Range Description

This species is only known with certainty from Gua Tengkuk Air cave at the top (1,000m asl) of Gunung Kajang, Pulau Tioman, Pahang, West Malaysia. Larvae matching the morphology, but not coloration, of this species have also been found at 400m asl on this mountain, so either L. kajangensis is not restricted to its highest elevations, or an additional species of Leptolalax might occur lower down. At most, it seems likely that the species is restricted to this island, so has a very small range.

Habitat and Ecology

The species occurs in a subterranean, obliquely oriented cavern, formed from the overhang of a pile of large boulders. The cave contains a small pond (3m by 4m) drained by a small subterranean stream (1-3m in width by 2-4cm in depth) that runs for 3-4m along the cave floor. Tadpoles of this species are found in the pond. Adults have been found sitting on large rocks next to the stream, 10m from the cave entrance and 10m below the external ground level.


There is no information on the current population status of this species.

Major Threats

There is no information available on threats to this species.

Conservation Actions

Pulau Tioman is designated as a wildlife reserve. There is a need for close monitoring of the population of this species, given its apparently extremely restricted range, and further research is needed to determine whether or not there are any major threats to this species.

Red List Status

Vulnerable (VU)


Listed as Vulnerable since it is only definitely known from one cave near the summit of a small island, and it is likely to have an area of occupancy of less than 20km2 and a correspondingly low population.
