Scientific Name:	Philautus neelanethrus
Species Authority:	Gururaja, Aravind, Ali, Ramachandra, Velavan, Krishnakumar & Aggarwal, 2007

Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii) ver 3.1
Year Published:	2008
Assessor/s:	K.V. Gururaja
Reviewer/s:	Simon Stuart, Neil Cox
Justification: Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.

Geographic Range [top]

Range Description:	This species is known from several localities in the Sharavathi River basin, in the central part of the Western Ghats, Karnataka State, India, at 534-692m asl (Gururaja et al., 2007). Within this elevational range it occurs quite widely in this river basin (Gururaja et al., 2007), and has also been located further to the north, as far as the Bedti River basin in the Uttara Kannada district of Karnataka, and south as far as Kudremukh National Park (K.V. Gururaja, pers. comm.).
Countries:	Native: India (Karnataka)

Population [top]

Population:	Its abundance varies through its range (Gururaja et al., 2007). There were 6-8 individuals/mhs (man-hours of search) in the Myristica swamps, where densities were relatively high, compared to the densities of 2-4 individuals/mhs observed in forested habitats (Gururaja et al., 2007).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	The region where this species occurs has an undulating terrain, with both evergreen and moist-deciduous forests in which this species occurs(Gururaja et al., 2007). In relatively flat areas there are freshwater habitats known as Myristica swamps, dominated by members of plant family Myristicaceae, and these sites are favoured by the species. The species is absent from unsuitable habitats within its range, such as rock outcrops, recently burnt areas, open/barren lands, agricultural fields, plantations, and built-up areas (Gururaja et al., 2007). It is presumed to breed by direct development without dependence on water.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	This species has lost much habitat within its range due to the construction of dams for hydropower, the extension of agricultural fields into forested areas, and urbanization, and its populations are now severely fragmented (Gururaja et al., 2007).
