This species is known from mountain areas on Mindanao Island in the Philippines. It has been recorded in at least half a dozen separate localities, and is found at 600-850m asl, and probably ranges higher than this.
Habitat and Ecology
It is known from lowland and submontane rainforest and associated agricultural habitats, where the adults are subterranean. The larvae inhabit unpolluted streams, rivers and quiet pools near streams. The adults and larvae have also been found in mud in recently cleared agricultural fields at forest edges.
It is apparently common, but is very localized and patchily distributed.
It has been suggested that the main threats to this species are logging, habitat conversion to agriculture, and pollution of streams and rivers from mining and agricultural effluents. However, the limited information available suggests that, as with other species of Ichthyophis, it is fairly adaptable to habitat modification, and might not be significantly threatened, except in local situations.
It is in need of taxonomic review (Wilkinson pers. comm.)
The taxonomic status of this species is unclear. Records of caecilians from several localities on Mindanao Island need to be properly identified.
