This species is known in Peninsular Malaysia from two localities: Batu Caves near Kuala Lumpur (the type locality), and Kuala Tahan in the Taman Negara National Park. In Sumatra it is known from three localities: two in Gunung Leuser National Park in Aceh (Iskandar pers. comm.), and one near Lahat in south Sumatra (Mumpuni pers. comm.). It is a low altitude species.
Habitat and Ecology
The type locality of this species was originally a limestone crag area surrounded by lowland forest. It is found in forested areas in Sumatra. It presumably breeds in slow-flowing streams, but no data are available to confirm this.
In Peninsular Malaysia there are no population data available for this species, which has not been reported in recent decades despite its type locality being extremely easy to access. In Sumatra this species is rare but it has been collected as recently as 1999.
The most serious threat through most of this species' range is likely to be forest clearance through logging. The type locality is now a partly quarried limestone crag surrounded by housing estates, and is annually flooded with pilgrims.
This species has been recorded from Gunung Leuser and Taman Negara National Parks. Remnants of the Batu Caves limestone outcrop should be effectively protected and restored where possible. This species' taxonomic status should also be reviewed.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
This species might be synonymous with Microhyla palmipes (see Berry 1975). However, Iskandar (pers. comm.) considers that it is a separate species.
