Pseudophilautus zimmeri (Ahl 1927)

Male holotype 31.6 mm SVL. Slender body. Head dorsally convex, with flat interorbital area. Snout blunt in profile, angled at 105 degrees (category 7 of Manamendra-Arachchi and Pethiyagoda 2005), with sharp canthal edges, concave loreal region, and flat internarial space. Tympanum oval, vertical, with prominent supratympanic fold. Pineal ocellus present. Vomerine teeth present. Lingual papilla absent. Fingers have lateral dermal fringe. Toes webbed medially. Tarsal fold lacking; tarsal tubercle present. Supernumerary tubercles present on palm and sole. Dorsum smooth with a few glandular warts. Head, dorsal surfaces of forelimb, thigh, shank and foot have glandular warts. Flanks, throat, chest, belly, and ventral surface of thigh granular.

Pseudophilautus zimmeri was a species endemic to Sri Lanka and was only known from the type locality of Galle ("Point de Galle, Ceylon"). The exact habitat that this species required is not known (Stuart et al. 2008).

This species has been found only at the type locality and is only known from the holotype, described by Ahl (1927). It has not been rediscovered despite extensive searches and is presumed extinct. Breeding is thought to have been through direct development, as is the case for other members of the genus Pseudophilautus (Stuart et al. 2008).

Habitat loss is believed to be the major factor in this species' extinction, since the area of the type locality is now heavily urbanized (Stuart et al. 2008).
