This species is known only from the type locality "Kottigehar, Kadur", and from a recently discovered population at Bhadrea, in Chicamangalore District, Karnataka, in the Western Ghats of India. The altitude of the type locality is not known, but it was most recently collected at an altitude of approximately 1,000m asl. It appears to have a very small distribution.
Habitat and Ecology
Presumably a forest species, it was recently collected close to a road and a stream. Like other members of the genus, it probably has aquatic larvae in streams.
The population status of this species is unknown.
The major threat to the species is general habitat loss as a result of agriculture, including paddy fields and cash crops such as coconut and cashew.
It is not known whether or not this species occurs in any protected areas. Further survey work is required to determine the current population status of the species and the limits of its distribution range. It is protected by national legislation.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Area of Occupancy is probably less than 100 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat
Rao (1937) originally described this taxon as Philautus kottigeharensis based on a single specimen from Kottigehar. Bossuyt and Dubois (2001) transferred the species from Philautus to Micrixalus. The holotype was lost and recently Bossuyt and Milinkovitch (2001) relocated the species from Bhadrea in Chicamangalore District very near to the type locality. Formal designation of the neotype is under way (S.D. Biju pers. comm.).
