Indosylvirana intermedia (Rao, 1937)

New records. INDIA • Karnataka: Udupi: Manipal, Herga , site code E (13.3729°N, 074.8015°E), obs. by MM & RS, 29 Apr. 2017, 41 individuals. Fig. 3N.

Identification. The SVL is 46– 42 mm in males and 66– 74 mm in females. This species has a bright, goldenyellowish dorsum. There are moderately developed dorso-lateral folds on the dorsum. This is the only Indosylirana species that has the thigh and tibia of equal length. We have not made measurements of these lengths, but our analysis of our photographs using ImageJ found the thigh and tibia length to be equal in our specimens. This species can be confused with I. aurantiaca (Boulenger, 1904) ; however, I. aurantiaca is much smaller, with the SVL from 27 to 32 mm, and there are weak dorso-lateral folds ( Biju et al. 2014; Oliver et al. 2015). The call is a series of short, low-pitched, harsh “chuck” sounds.

Habitat. This species is often found in waterlogged paddy fields and ephemeral pools with some grass and small shrubs. This frog is known from near sea level to 1000 m above sea level.

Distribution. This species is endemic to the Western Ghats, from north of the Palghat Gap.
