Description
Female holotype 31 mm SVL (according to original description in Boulenger 1891; now 29.8 mm, according to Bossuyt and Dubois 2001). Dorsum smooth (Gururaja et al. 2007). Snout not pointed (Gururaja et al. 2007). Similar to R. luteolus, but R. travancoricus has conspicuous black markings in the preserved specimen, and a shorter snout that is not pointed (Kuramoto and Joshy 2003).

Endemic to the Western Ghats of India, from the type locality "Bodanaikanur, Travancore, at the foot of the hills on the eastern side", Tamil Nadu. It was an arboreal species found in tropical moist evergreen forests, up to 400 m asl (Stuart et al. 2008).

Life History, Abundance, Activity, and Special Behaviors
Known only from the holotype specimen. Raorchestes travancoricus has not been recorded since its description over 100 years ago (Boulenger 1891), despite extensive searches. This species is presumed extinct. It is believed to have been a direct developer, like other species in the genus Raorchestes (Stuart et al. 2008).

Trends and Threats
This species' demise was due to deforestation of the land for urban development and agricultural use (Stuart et al. 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Urbanization
