Indirana leithii (Leith's leaping frog, Leith's frog, Boulenger's brown frog, Matheran leaping frog, or Matheran Indian frog) is a species of frog in the family Ranixalidae. [3] 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. [3] [4] [5] [1]
The specific name leithii honours Andrew Henderson Leith, a physician who worked as Sanitary Commissioner in Bombay. [6]
Adult males measure 19–29 mm (0.7–1.1 in) and adult females 24–36 mm (0.9–1.4 in) in snout–vent length. [4] The tympanum is two-thirds of the eye diameter; a strong supra-tympanic fold runs from the eye to the shoulder. The fingers and toes bear enlarged discs; the toes are two-thirds webbed. Dorsal skin is rough with number of folds. Colouration is brownish with many, closely set black spots. The limbs are cross-barred. The venter is white while the throat is finely mottled with brown. [7]
The following description is adopted from George Albert Boulenger's "Fauna of British India": [8]
Vomerine teeth in two oblique groups are set just behind the level of the choanae. A free, pointed papilla sits on the middle of the tongue. The head is moderate; the snout is obtuse, with obtuse canthus rostralis and concave loreal region; the nostril is nearer to the end of the snout than to the eye; the interorbital space is a little narrower than the upper eyelid; the tympanum is distinct, two thirds the diameter of the eye. The fingers are moderate, the first extending not quite as for as second; the toes are two-thirds webbed, the web reaching the disks of the third and fifth toes; tips of fingers and toes dilated into small but well-developed disks; subarticular tubercles moderate; a single, small, oval inner metatarsal tubercle; no tarsal fold is present. The tibio-tarsal articulation reaches halfway between the eye and the end of the snout. The skin of the back has small scattered longitudinal warts; a strong fold runs from the eye to the shoulder. It is brown above, with small dark spots; limbs with dark transverse bands; lower parts white, throat mottled with brown. From snout to vent 1.25 inches.
This frog has no call within the human audible range. [1]
This frog lives in the northern part of the Western Ghats. It is a terrestrial species, inhabiting evergreen and partially evergreen forests near basalt cliffs. It has been observed on the ground near streams and in cracks in rocks or among the leaf litter. This frog has been observed between 25 and 1329 meters above sea level. [1]
During the breeding period, the frogs convene in caverns, sometimes in great numbers. The frog lays eggs on wet rocks or in cracks in rocks. The tadpoles use their mouths to adhere to the rocks, where they eat algae. The tadpoles are only semi-aquatic. The hind legs grow in at an earlier age than on the tadpoles of other species. [1]
The frog's range includes several protected parks: Bhimashankar Wildlife Sanctuary, Kalsubai Harishchandragad Wildlife Sanctuary, Tamhini-Sudhagad Wildlife Sanctuary, Phansad Wildlife Sanctuary, Sahyadri Tiger Reserve, and Vansda National Park. [1]
The adult frog eats ants, grubs, and hemipterans. The tadpoles eat algae. [1]
Scientists believe this frog is not in danger of dying out, but it is in some danger from habitat loss due to the conversion of forest to agriculture and infrastructure construction. Anti-landslide measures involving shortcrete can harm this frog by filling in the cracks in the rocks where frogs would lay their eggs. Wood harvesting at a subsistence level also poses some threat, but a minor one. [1]
Scientists also think climate change could hurt this frog. Because climate change has changed the weather, some of these frogs have dried out and died. [1]
Scientists have seen the fungus Batrachochytrium dendrobatidis on this frog, but they do not know its specific morbidity or mortality. Batrachochytrium dendrobatidis causes the fungal disease chytridiomycosis. [1]
The fungoid frog or Malabar Hills frog is a colourful frog found on the forest floor and lower vegetation in the Western Ghats in south-western India from Bombay to Kerala. It is very similar to another species with which it overlaps partly in range, Hydrophylax bahuvistara which extends further into parts of central India. Although restricted in range within peninsular India, they are of least conservation concern. Their upper parts vary in colour from brownish-red to bright crimson.
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".
Indirana beddomii, Beddome's leaping frog, Beddome's Indian frog, or simply Beddome's frog, is a species of frog found in the Western Ghats. They are usually detected by their long leaps as they flush from the ground when disturbed. The species is named after the naturalist Richard Henry Beddome.
Micrixalus saxicola is a species of frog in the family Micrixalidae, found in forest streams in the Western Ghats of India.This frog has a brown colored dorsum and a white ventral side with irregular white specks on its dark brown throat and chest. Its smooth skin and cryptic coloration allow it to blend into its surroundings while resting or calling. The males of the species are territorial, and will use calling, foot tapping, and foot flagging to warn off competition. M. saxicolais is described by the IUCN as a vulnerable species due to habitat loss, fragmentation, and human interference.The frog also threatened by infection by the fungus Batrachochytrium dendrobatidis.
Indirana semipalmata is a species of frog endemic to the Western Ghats region of southern India. They are small frogs, reaching lengths of about 36 mm (1.4 in) from snout to vent. The species breeds during the monsoons, laying their eggs on moist rocks and tree bark. Their tadpoles are terrestrial – hatching, feeding, and undergoing metamorphosis without ever entering any standing bodies of water.
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.

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.
Walkerana is a genus of frogs in the family Ranixalidae. The genus is endemic to the Western Ghats in the states of Kerala and Tamil Nadu, India.
