Walkerana is a genus of frogs in the family Ranixalidae. [1] [2] The genus is endemic to the Western Ghats in the states of Kerala and Tamil Nadu, India. [2] It was erected in 2016 to host three species of Indirana that represented a genetically and morphologically distinct clade within the then broadly defined Indirana. [1] Until Walkerana muduga was described in 2020, the genus was only known from the southernmost part of the Western Ghats south of the Palghat Gap. [3]
This genus is named for Sally Walker, conservationist from the Zoo Outreach Organisation. [1] The genus was then renamed into Sallywalkerana because of homonymy with the cricket genus WalkeranaOtte and Perez-Gelabert, 2009, but the latter may be nomen nudum . [2]
Walkerana is genetically distant clade within the family Ranixalidae. It differs from its sister taxon Indirana in having extremely reduced webbing, with one phalange free of webbing on first and second toes (none in Indirana), and three phalanges free on the fourth toe (2–2½ in Indirana). Furthermore, the first finger is shorter than the second one in Walkerana, while in Indirana (with the exception of I. leithii ) they are of equal length or the first finger is longer than the second. [1]
There are four recognized species: [2] [3]
Dinesh and colleagues have identified one additional species based on one specimen from north of the Palghat Gap, but did not describe it because of the poor preservation of the specimen in question. [3]
Nyctibatrachus is a genus of frogs endemic to the Western Ghats of southwestern India. Their common name is night frogs. Their scientific name also means "night frog", in reference to their habits and dark color. They are the only extant members of the monotypic subfamily Nyctibatrachinae. Currently, 35 species belong to Nyctibatrachus.
Indirana is a genus of frogs in the family Ranixalidae. These frogs are endemic to the Western Ghats of India. They are sometimes known under the common name Indian frogs, whereas members of their parent family are named "leaping frogs".
Sphaerotheca is a genus of true frogs. They can be found in South Asia. Molecular data suggest that they are closely related to Fejervarya, perhaps as a monophyletic group within a paraphyletic Fejervarya.
The Malabar gliding frog or Malabar flying frog is a rhacophorid tree frog species found in the Western Ghats of India.
Indirana leithii is a species of frog in the family Ranixalidae. It is endemic to the northern Western Ghats of India. As currently defined, its range is restricted to the states of Maharashtra and southern Gujarat; earlier records elsewhere refer to other species.
Bufoides is a small genus of true toads, family Bufonidae. The genus is endemic to Northeast India, with one species known from the Garo and Khasi Hills.
Walkerana diplosticta, also known as the spotted leaping frog, Malabar Indian frog, rufous leaf-hopper frog, and Günther's frog, is a species of frog in the family Ranixalidae. It is endemic to the Western Ghats south of the Palghat Gap and only known with certainty from the states of Kerala and Tamil Nadu, India. Localities with confirmed records include the Kalakkad Mundanthurai Tiger Reserve.
Walkerana phrynoderma is a species of frog endemic to the Anaimalai Hills, of the Western Ghats of Kerala and Tamil nadu states in southern India. This species is known from Munnar, Eravikulam National Park, Valparai tea gardens, Anamalai Tiger Reserve, Grass Hills National Park and Palni hills. It is a very rare terrestrial frog species associated with leaf-litter in tropical moist forest. It is threatened by habitat loss caused by subsistence wood collecting. It has the status of one of the "Top 100 Evolutionarily Distinct and Globally Endangered Amphibians".
Indirana tenuilingua is a species of frog that is considered nomen inquirendum. It is only known from the type series, now lost, from its type locality, Kemphole, in the Western Ghats of India. It is sometimes known as Rao's Indian frog or slender-tongued frog.
Raorchestes flaviventris is a species of arboreal, nocturnal, frog of the family Rhacophoridae. It is endemic to the Western Ghats, South India. Its common name is yellow-bellied bush frog.
Rhacophorus lateralis is an endangered rhacophorid tree frog endemic to the Western Ghats in South India. It has several common names: small tree frog, Boulenger's tree frog, small gliding frog, and winged gliding frog. After its original description in 1883 by George Albert Boulenger, the frog was rediscovered in Coorg in 2000 and has since been found in many parts of the Western Ghats around southern Karnataka and northern Kerala. Along with R. malabaricus, it is one of the few anuran amphibians in India that constructs its nest above the ground using leaves.
Microauris is a monotypic genus of agamid lizard. Its only species is Microauris aurantolabium, also known as the small-eared dragon or orange-lipped forest lizard, found in the forests of the southern Western Ghats and is currently known from the Kalakkad Mundanthurai Tiger Reserve. The species was formerly included in Pseudocalotes andamanensis of the Andaman Islands, but recognized as distinct in 2008. It was also classified under Calotes until 2018, where it was transferred to its own genus, Microauris, on the basis of its divergence from Calotes.
Raorchestes ochlandrae is a species of shrub frog in the family Rhacophoridae. It is endemic to the Western Ghats, India. This species of the oriental shrub frog was first described from Kakkayam Reserve Forest of Calicut district, Kerala state, in the southern Western Ghats in 2007 but has since been recorded at many other sites along the Western Ghats. The specific name ochlandrae refers to microhabitat of the species, bamboo Ochlandra setigera.
Raorchestes is a genus of frogs in the subfamily Rhacophorinae that are found in mountainous regions of South Asia, Southeast Asia, and southern China. A recent study places Raorchestes as a sister taxon of Pseudophilautus. Before the description of the genus in 2010, species now in Raorchestes had been assigned to genera Ixalus, Philautus, and Pseudophilautus.
Ranixalidae is a family of frogs commonly known as the leaping frogs or Indian frogs. They are endemic to central and southern India.
Indirana chiravasi is a species of frog endemic to the Western Ghats of India. It is only known from its type locality, the laterite plateaus by the hill-station of Amboli, Maharashtra. It was described in 2014 by a team of three scientists from IISER, Pune and MES Abasaheb Garware College.
Monilesaurus is a genus of lizards in the draconine clade of the family Agamidae and is a new genus described in 2018. Currently it consists of 4 species, with 2 new species and 2 species split from the genus Calotes.
Walkerana muduga, also known as the Muduga mountain leaping frog or Muduga leaping frog, is a species of frog in the family Ranixalidae. It is endemic to the Western Ghats of India and known from the Elivai Malai range, north of the Palghat Gap in Tamil Nadu. All other known species of Walkerana occur south of the Palghat Gap, and molecular data suggest that Walkerana muduga is deeply divergent from the more southern species. However, there is another, as yet undescribed lineage from north of the Palghat Gap that is known from a single, poorly preserve specimen.
Nyctibatrachus periyar is a species of frog endemic to the Western Ghats of India. It is known only from the Periyar tiger reserve from where it was described in 2011.
Indirana tysoni, also known by its common name Tyson's leaping frog is a species from the genus Indirana. The species was originally described in 2016 by Neelesh Dahanukar, Nikhil Modak, Keerthi Krutha, P. O. Nameer, Anand D. Padhye, and Sanjay Molur.
