Taxonomic notes: Section empty

This species is found in the mountains of Mindanao and Dinagat Islands, in the Philippines.

It is fairly common where it occurs, but it has a patchy distribution.

It inhabits cool mountain streams and rivers in montane rainforest where it also breeds and the larvae develop.

Section empty

This species inhabits high-elevation forests, which are generally less threatened by habitat conversion, agriculture, and human encroachment, and the pollution of streams and rivers. Regardless, some populations of this species are subject to these threats.

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

It is known from several protected areas, including Mount Malindang National Park. Conservation measures must include the regulation and proper disposal of pesticides and herbicides, and the protection of the remaining rainforest, especially high-elevation riverine habitats and gallery forests, on Mindanao. The taxonomic status of this species requires further study.

• 5.1.2 National level
• 2.1 Site/area management

Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on Mindanao and Dinagat in the Philippines.
