This species is endemic to south-western Sri Lanka. It has been recorded at elevations of 20-1,525m asl.
Habitat and Ecology
It is a subterranean species present in forests, rubber plantation areas, paddy fields, rural gardens and farms, wetlands (boggy and muddy areas), and pastureland. Adults are often found in humus and other rotten vegetation. It is oviparous with terrestrial eggs and aquatic larvae in streams.
It appears to be less common that Ichthyophis glutinosus. It is not known from many specimens.
The species might be threatened locally by extreme habitat loss, due to agroindustry, and agro-chemical pollution (land and water based).
It has been recorded from Peak Wilderness Forest Reserve and Sinharaja Forest Reserve, which is a World Heritage Site.
Red List Status
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 habitat in Sri Lanka.
