New genus of tree frog discovered, found in Andamans and Northeast India

Context: Scientists and researchers from the University of Delhi and the Zoological Survey of India have discovered a genus of tree frog found in the Andaman islands and the northeast.

• Named after Sri Lankan taxonomist Rohan Pethiyagoda, the frogs of the new genus Rohanixalus are characterised by a
  • rather small and slender body (size about 2 to 3 cm long),
  • a pair of contrastingly coloured lateral lines on either side of the body,
  • minute brown speckles scattered throughout the upper body surfaces, and
  • light green coloured eggs laid in arboreal bubble-nests.
• Based on DNA studies, the new genus is also revealed to be a distinct evolutionary lineage from all previously known tree frog genera.
• Frog species in this genus Rohanixalus, which are known to inhabit forested as well as human-dominated landscapes right from the northeast, the Andaman islands, Myanmar, Thailand, Malaysia, Indonesia, Vietnam, Laos, and Cambodia, up to southern China.
• Another interesting aspect is that the first member of the tree frog family, Rohanixalus vittatus (Striped Bubble-nest frog), is reported from the Andaman islands.
