Removed from the synonymy of Philautus leucorhinus by Manamendra-Arachchi and Pethiyagoda, 2005, Raffles Bull. Zool., Suppl., 12: 210, where it had been placed by Kirtisinghe, 1957, Amph. Ceylon: 69. Manamendra-Arachchi and Pethiyagoda, 2005, Raffles Bull. Zool., Suppl., 12: 210–212, presented an account and noted this extinct species to be similar to Pseudophilautus nasutus, Pseudophilautus adspersus, Pseudophilautus dimbullae, and Pseudophilautus zal (all as Philautus). See map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 140, who regarded the species as extinct. Regarded as extinct by Batuwita, Udugampala, De Silva, Diao, and Edirisinghe, 2019, J. Anim.
