Micrixalus kottigeharensis (commonly known as Kottigehar dancing frog, Kottigehar bubble-nest frog or Kottigehar torrent frog) is a species of frog in the family Micrixalidae. It is endemic to the Western Ghats in Karnataka, India.[2] It is one of the "Top 100 Evolutionarily Distinct and Globally Endangered (EDGE) Amphibians".[3] The specific name means "from Kottigehara". The tadpoles of Micrixalus kottigeharensis are fossorial. Females have been observed excavating egg-laying cavities using their hind limbs, with recorded cavity depths of approximately 32 mm.[4]

Taxonomy

Until 2014, both Micrixalus narainensis and Micrixalus swamianus were considered separate species, but have since been classified as junior synonyms of M. kottigeharensis based on phylogenetic analyses.[5]

Description

Male Micrixalus kottigeharensis grow to a snout–vent length of 22–24 mm (0.87–0.94 in) and females to 28–33 mm (1.1–1.3 in).[5]

Habitat

The preferred habitat of Micrixalus kottigeharensis are fast-flowing streams in primary and secondary forests.[5] It is threatened by habitat loss.[1] The species is most often found in shaded, structurally complex stream habitats and is particularly associated with emergent rocks, riffles and braided sections[6]

Geographic distribution

Endemic to the central Western Ghats of India.[7]
