The Seychelles frogs (Sooglossidae) are a family of frogs found on the Seychelles Islands and India. Until recently, this family was believed to include the genera Nesomantis and Sooglossus, but following a major revision of amphibians in 2006,[1] the genus Nesomantis was named a junior synonym of Sooglossus; conversely, the recently discovered purple frog, which was initially assigned to a distinct monotypic family (Nasikabatrachidae), is now included in the Sooglossidae.[2]

All of the species are relatively small terrestrial frogs, about 4 cm (1.6 in) in length, hiding under fallen leaves or in rock crevices. They are unusual for the neobatrachials, in that they undertake inguinal amplexus, a primitive version of amplexus. Except for N. sahyadrensis, they lay their eggs on moist ground, rather than in water. Several species lack tadpoles, with the eggs hatching directly into froglets.[3] The tadpoles of S. sechellensis are carried, abnormally, on the backs of the female frogs until metamorphosis.[4]

There is no fossil record for the family. Ancestors diverged when the Seychelles Islands split from India about 100 million years ago.

Taxonomy[edit]

The family was first described in 1931 by Gladwyn Kingsley Noble (1894–1940).
