Nannophrys
''Nannophrys'' is a genus of frogs endemic to Sri Lanka.

Nannophrys Ceylonensis
''Nannophrys ceylonensis'', commonly known as the Sri Lanka rock frog or the Ceylon streamlined frog, is a species of frog.

Nannophrys Guentheri
''Nannophrys guentheri'' (Gunther's streamlined frog) is an extinct species of frog in the family Dicroglossidae. It was endemic to Sri Lanka. The species was first identified in 1882 by George Boulenger and named after the German-born British zoologist Albert Günther. It is not known where in Sri Lanka the specimens were found. Taxonomy ''Nannophrys guentheri'' has not been observed since the type specimens were collected. These are poorly preserved and might not be distinct from ''Nannophrys ceylonensis''. Genus ''Nannophrys'' used to be placed in the large frog family Ranidae but a phylogenetic study was undertaken using DNA sequences and it is now included in the family Dicroglossidae. Description ''Nannophrys guentheri'' was a small species, with snout to vent length given as 28.5 mm for males. Vomerine teeth are in two indistinct groups behind the choanae (the inner part of the nostrils). Lower jaw has slight traces of bony prominences in front. Head is rather sma ...

Nannophrys Naeyakai
''Nannophrys naeyakai'', also known as the Sri Lanka tribal rock-frog or Sri Lanka tribal rock frog, is a species of frogs in the family Dicroglossidae. It was described as a new species in 2007. It is endemic to Sri Lanka, where it is only known from two localities in Ampara and Monaragala Districts. ''N. naeyakai'' can be distinguished from the other ''Nannophrys'' species by the details of the tubercles on the fourth toe, sharp and narrow symphysial knob on the anterior edge of mandible and small palmar tubercles. The specific name ''naeyakai'' refers to the "''naeyaka''", spirits of deceased relatives in the believes of Vedda people living in the type locality area. Description Adult males measure and adult females in snout–vent length. The head is depressed and wider than it is long. The snout is rounded. The tympanum is distinct. The finger and toe tips are bluntly rounded; no webbing is present. Skin is somewhat rough dorsally with warty pustules on the flanks. The ...

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Amphibian Genera
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Dicroglossidae
The frog family Dicroglossidae 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. The Dicroglossidae were previously considered to be a subfamily in the family Ranidae, but their position as a family is now well established. __TOC__ Subfamilies and genera The two subfamilies contain 231 species in 13–15 genera, depending on the source. Dicroglossinae Anderson, 1871 — 211 species in 13 genera: Occidozyginae Fei, Ye, and Huang, 1990 — 20 species in two genera: * '' Ingerana'' Dubois, 1987 (two species) * '' Occidozyga'' Kuhl and Van Hasselt, 1822 (18 species) Phylogeny The following phylogeny of Dicroglossidae is from Pyron & Wiens (2011) with the split of Euphlyctis sensu lato based on Yadav ''et al.''

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Sri Lanka
Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, also known historically as Ceylon, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, separated from the Indian subcontinent, Indian peninsula by the Gulf of Mannar and the Palk Strait. It shares a maritime border with the Maldives in the southwest and India in the northwest. Sri Jayawardenepura Kotte is the legislative capital of Sri Lanka, while the largest city, Colombo, is the administrative and judicial capital which is the nation's political, financial and cultural centre. Kandy is the second-largest urban area and also the capital of the last native kingdom of Sri Lanka. The most spoken language Sinhala language, Sinhala, is spoken by the majority of the population (approximately 17 million). Tamil language, Tamil is also spoken by approximately five million people, making it the second most-spoken language in Sri Lanka. Sri Lanka has a population of appr ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
