They are endemic to the Western Ghats of southern India. They are the sister taxon to a larger clade consisting of Chiromantis, Feihyla, Taruga, Polypedates, and Rhacophorus.[2][3] The name of the genus combines words "Ghats" and "Ixalus". The former refers to the Western Ghats, and the latter to now-abandoned genus name that lives as the suffix in many generic names for rhacophorid frogs.[1] DescriptionGhatixalus are medium-to giant-sized frogs with adult males measuring {{convert|39|-|82|mm|abbr=on}} and females {{convert|58|-|67|mm|abbr=on}} adults (male SVL 38.8–82 mm, female 58.1–66.7 mm) in snout-vent length. They have a dorsal color pattern with dark brown prominent blotches. Eggs develop in foam nests followed by a free-swimming tadpole stage. Their habitat is associated with mountain streams throughout their life cycle.[1][3] Distribution and natural historyThis exclusively Shola forest specialist genus is distributed only in the high elevations of Nilgiris and Anaimalai-Palnis, only above 1600 m asl. Most of the sightings were near streams and streamside often on bare ground, grass clumps on ground or rocks nearby. Although belonging to rather arboreal frog family, these frogs are terrestrial animals. SpeciesThere are only 3 recognized species in the genus Ghatixalus:[2]
The Palakkad Gap is believed to be a prominent biogeographic barrier that have caused speciation between G. asterops and G. variabilis, which are sister species.
