Interorbital and internarial regions are concave. Vomerine teeth absent. Lingual papilla present. Subdermal tympanum with prominent supratympanic fold. Supernumerary tubercles present on palm. Fingers have weakly developed dermal fringes. Toes are medially webbed. Calcar absent and tarsal fold absent. Dorsum and snout are shagreened, with a few glandular warts. Interorbital area and the side of the head are shagreened. Throat and chest are granular and smooth, while the belly and underside of the thigh are granular and rough. Flanks are granular. The dorsal forelimb, thigh, shank, and foot are shagreened, with a few granular warts (Manamendra-Arachchi and Pethiyagoda et al. 2005).

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Sri Lanka

 

View distribution map in BerkeleyMapper.
This species was endemic to Sri Lanka, but a precise distribution map cannot be made since the locality is described only as "Ceylon". The exact habitat that this species required is not known (Stuart et al 2008).

Life History, Abundance, Activity, and Special Behaviors
This species is only known from the holotype (NHMB 1236), which was donated to the NHMB collection (Basel, Switzerland) in 1882; it has not been rediscovered since 1882 despite extensive searches and is presumed extinct. Breeding is believed to have been through direct development, as is the case for other members of the genus Pseudophilautus (Stuart et al 2008).

Trends and Threats
The exact reasons for extinction are not known, but the major factor is likely to be habitat loss (Stuart et al 2008).
