List of amphibians of Sri Lanka

Sri Lanka is host to over 110+ species of amphibians, of which over 90 species is being endemic to the country.^[1] The 85% of endemicity ratio makes Sri Lanka the country which has the highest amphibian endemism in Asia.^[2] During the past decade the finding of new amphibians in Sri Lanka has increased significantly.^[3] The first amphibian review in Sri Lanka in 1957 identified 35 species. In 1996 the number of amphibian species has raised to 53 based on research of museum collections and also a field survey. More than 250 species were proposed based on this field survey by Pethiyagoda and Manamendra-Arachchi in 1998. However Meegaskumbura et al. revised the number to around 140 species,^[4] and the discovery of over "new" 100 species has been criticised.^[5] As at 2016, 120 descriptions of amphibian species have been published, with 110 endemics.^[6] Three caecilian species has been identified with one undescribed species.

Sri Lanka harbours three endemic genera, Adenomus, Nannophrys, and Lankanectes.^[3] Most of the new species is of the genus Philautus was assigned to genus Pseudophilautus recently. So, there is no any member in Philautus genus in Sri Lanka. The Pseudophilautus pardus and P. maia, the species known only from collections made prior to 1876 are described as new species in 2007, but both are decided to be extinct species.^[7] Sri Lanka also ranked highest in Asia for having highest percentage of extinct and threatened amphibian species.^[2] In the 20th century the country has lost 20% of its amphibians and more than half of remaining species is on the verge of extinction. Of world's 34 amphibian fauna extinct in last 500 years, 19 of them are from Sri Lanka.^[3] The habitat loss is attributed as the main cause of threats while fragmentation, use of pesticides, and air pollution are among others. In April 2015, Mendis Wickrremasinghe et al. described another endemic Pseudophilautus species P.dilmah.
