This species is so far known only from the eastern flank of Phnom Samkos, in Pursat Province, in the Cardamom Mountains of Cambodia, at 501m asl (Grismer et al., 2007). It is expected to occur more widely.
Habitat and Ecology
The only known specimens were found seated 1.5m above the ground on the leaves of small shrubs among grassy vegetation along the edge of a temporary rain pool at the edge of a wide trail surrounded by hill evergreen forest (Grismer et al., 2007). It is presumed to breed in water by larval development. It is not known whether it can adapt to anthropogenic habitats.
There is no information on its abundance. It is known from only two specimens (Grismer et al., 2007) found among large choruses of other Chiromantis species.
A wide road has just been graded through the type locality in the exact place where the two specimens were found (L. Grismer pers. comm.). If the species occur more widely, as is expected, it might be affected by habitat loss for other reasons.
It is found in the Phnom Samkos Wildlife Sanctuary (L. Grismer pers. comm.). Surveys are needed to determine its geographic range, abundance, ecological requirements, threats and conservation needs.
