Pseudophilautus nasutus (Günther 1869)

Known only from the preserved holotype (Günther 1869). Adult male 17.4 mm SVL. Head dorsally flat. Snout angle of about 80 degrees (category 2 of Manamendra-Arachchi and Pethiyagoda et al. 2005), with sharp canthal edges and concave loreal regions. Interorbital space flat; internarial space concave. Tympanum discernible, oval-shaped, and vertically oriented, with prominent supratympanic fold. Pineal ocellus lacking. Vomerine teeth lacking. Lingual papilla not present. Lateral dermal fringe absent on fingers. Supernumerary tubercles present on palm and sole. Toes webbed medially. Calcar present. Tarsal tubercle present. Dorsum tuberculated; dorsal and lateral regions of head with glandular warts. Median dermal ridge runs from tip of snout to vent. Limbs have a few glandular warts dorsally. Upper flank smooth, with lower flank granular. Throat, chest, belly, and underside of thigh are all granular, but the chin is smooth. Male holotype lacks nuptial pads but has internal vocal slits (Manamendra and Pethiyagoda 2005).Coloration in preservative: Uniform dark brown dorsum; limbs crossbarred (Manamendra and Pethiyagoda 2005).

Endemic to Sri Lanka, but the type locality is described only as "Ceylon" (Stuart et al. 2008). Habitat requirements are unknown (Stuart et al. 2008).

Known only from the holotype; Pseudophilautus nasutus has not been recorded since its description (Günther 1869). It is believed to have been a direct developer, like other species in the genus Pseudophilautus (Stuart et al. 2008).

The exact reason for this species' decline is not known, but it is believed that habitat loss was the major factor in its eventual extinction(Stuart et al. 2008).
