Limnonectes timorensis (common name: Timor river frog [3] and Timor wart frog [5] ) is a species of frogs in the family Dicroglossidae. It is endemic to the island of Timor at the eastern end of the Lesser Sunda Islands. [5] In Timor-Leste it is an infrequent species associated with rivers in tropical montane forests above 1000 m altitude. [3]

Frog Order of amphibians

A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura. The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforests. There are over 6,300 recorded species, accounting for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history.

Dicroglossidae family of amphibians

The Dicroglossidae family of frogs occurs in tropical and subtropical regions of Asia and Africa, with most genera and species being found in Asia. The common name of the family is fork-tongued frogs.

Timor island at the southern end of Maritime Southeast Asia

Timor is an island at the southern end of Maritime Southeast Asia, north of the Timor Sea. The island is divided between the sovereign states of East Timor on the eastern part and Indonesia on the western part. The Indonesian part, also known as West Timor, constitutes part of the province of East Nusa Tenggara. Within West Timor lies an exclave of East Timor called Oecusse District. The island covers an area of 30,777 square kilometres. The name is a variant of timur, Malay for "east"; it is so called because it lies at the eastern end of the Lesser Sunda Islands. Mainland Australia is less than 500 km away, separated by the mentioned Timor Sea.

Description

This species has a brown band on its head that starts near the tip of its snout, continues along the canthus rostralis, and through the eye, and then completely envelops the tympanum. It has warts on its skin that are normally located in a concentration on the dorsum. The fingertips of this species are somewhat swollen and wide at the tips. However, they do not have a marginal fold outlining the disk pad. The first finger is always longer than the second. There is a dorsolateral fold that starts from just behind the eye, and runs dorsally to the groin. The tympanum is almost equal in size to the eye. [3]
