Pseudophilautus oxyrhynchus (Günther 1872)

Known only from the lectotype, an adult female of 18.6 mm SVL. Elongate body, dorsally flat head with a concave interorbital region. Snout angled at about 70 degrees (category 0 of Manamendra-Arachchi and Pethiyagoda 2005), with a concave internasal area, sharp canthi, and flat loreal region. Tympanum oval-shaped, oblique, with a supratympanic fold. Toes medially webbed. Calcar present. Dorsum, flanks, and venter are smooth; the belly is granular (Manamendra-Arachchi and Pethiyagoda 2005). Color in preservative: Dark brown dorsum and venter. Limbs have indistinct crossbars (Manamendra-Arachchi and Pethiyagoda 2005).

Endemic to Sri Lanka, but the exact type locality is unknown ("Ceylon") (Stuart et al. 2008).

This species is only known from the lectotype. It has not been rediscovered 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).

Habitat loss is likely to have been the major factor in the population decrease and eventual extinction of this species (Stuart et al. 2008).
