RANGE DESCRIPTION
This species is known from the northwest Panay Peninsula and the Central Panay Mountain Range on Panay Island, in the Philippines, separated by an open area without tree cover. It occurs at elevations from 250–1,750 m asl, its extent of occurrence (EOO) is 3,322 km2, and it is considered to occur at two threat-defined locations.

DESCRIPTION
It is common to abundant at high elevations, but scarce at lower elevations. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

HABITAT AND ECOLOGY
This species inhabits arboreal microhabitats in lowland and mossy montane rainforests. It breeds by direct development in shrub layer vegetation, laying its eggs on the upper surfaces of leaves.

Threats in detail
THREATS
Although subpopulations occurring at higher elevations may currently be subject to fewer threats, those found at lower elevations are threatened by extensive habitat loss due to small-scale agriculture, wood collection for firewood and charcoal making, and road building.
