Rohanixalus is a genus of tree frogs in the family Rhacophoridae native to the Andaman islands and Indo-Burma region. [2] [3] The genus was established in 2020 by Indian herpetologist S.D. Biju of the University of Delhi and his colleagues. [1] The genus comprises eight species. [2]

Contents

Etymology

The genus was named after Sri Lankan taxonomist Rohan Pethiyagoda, who is a prominent Ichthyologist responsible for the discovery and/or description of almost 100 new species of vertebrates from Sri Lanka, including fishes, [4] amphibians [5] and lizards, [6] [7] in addition to 43 species of freshwater crabs. [8]

Description

The species of the genus characterised by a small and slender body with a size about 2 to 3 cm (0.79 to 1.18 in) long. There is a pair of contrastingly colored lateral lines on either side of the body. [3] Some minute brown speckles can be found scattered throughout the upper body surfaces. Females known to lay light greenish eggs in arboreal bubble-nests. Female mothers show maternal egg attendance where the mother attends the egg clutches until hatching and later assists in release of the tadpoles into the water. [9]

Distribution

The species are distributed throughout northeast, the Andaman islands, Myanmar, Thailand, Malaysia, Indonesia, Vietnam, Laos, and Cambodia, up to southern China. [9]
