Taxonomic notes: Section empty

This species is found in many parts of Luzon including the adjacent smaller islands of Polillo, Palaui, Catanduanes, and Marinduque, in the Philippines. It probably occurs a little more widely than current records suggest, especially in areas between known sites.

It is common in forested areas and disturbed areas near forest.

This species inhabits undisturbed and disturbed streams and rivers in lower montane and lowland forests. It breeds and lays its eggs in clean streams and rivers, and the larvae develop in quiet side pools.

Important threats to this species are the loss of lowland rainforest (due to agricultural development and logging) and the pollution of mountain streams and rivers, especially due to agricultural effluents.

• 2.1.3 Agro-industry farming
• 9.3.2 Soil erosion, sedimentation
• 9.3.4 Type Unknown/Unrecorded
• 5.3.5 Motivation Unknown/Unrecorded
• 2.1.1 Shifting agriculture
• 2.1.2 Small-holder farming

Its range includes a few protected areas. The most important conservation measure needed is to designate the remaining tracts of intact lowland rainforest on Luzon as protected areas.

• 2.1 Site/area management
• 1.1 Site/area protection

Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable.
