New Frogs Genus Found in the Northeast
Jan 22, 2016

An international team of researchers led by a Delhi University-based scientist discovered a class of frogs that grow in tree holes and, as tadpoles feed on eggs laid by their mother in the north-east region.

  • The new frog has been named Frankixalus Jerdonii and was once considered a species lost to science.

  • This genus remained unnoticed by researchers probably because of its secretive life in tree holes.

  • Researchers found these frogs in 2005 during explorations in Assam and Arunachal Pradesh, among other places, but had taken a decade to publish about them because of the complexities involved in ensuring that it was indeed an entirely new genus and not merely a known species.

  • Frogs of the newly described genus are relatively large (between 37-50 mm long) with big, bulging eyes and blunt snouts and are found on forest canopies and inside bamboos slits. 

  • Due to insufficient food resources in tree holes, the mother exhibits ‘remarkable parental care’ by laying unfertilised eggs to feed her tadpoles. 

  • Tree frogs occur across sub-Saharan Africa, China, much of tropical Asia, Japan, the Philippines and Sulawesi.

  • In the last two decades, India has reported a rapid rise in the discovery of frog species from the Western Ghats and, more recently, the north-eastern States. 

The research team comprised Ph.D. students of Sathyabhama Das Biju (renowned Indian Biologist) and researchers from National Centre for Cell Science (Pune), University of Peradeniya (Sri Lanka), Vrije Universiteit Brussel (Belgium) and American Museum of Natural History (USA).

Background:
In 1870, British naturalist T.C. Jerdon collected two specimens of a tree frog from forests of Darjeeling and preserved them at Natural History Museum, London. The frog was not found in the wild for over 150 years and was scientifically deemed lost. It remained a mysterious creature-a victim of mistaken identity ever since.
