New species of urban lizard found in Guwahati-THE HINDU-17-02-2020

News:

Guwahati, the largest city in the Northeast, has yielded a new species of lizard – the urban bent-toed gecko.

Markedly different

The study on the urban bent-toed gecko has been published in the latest edition of Zootaxa, a peer-reviewed scientific mega journal for animal taxonomists. “All bent-toed geckos in Northeast India were thought to be a single species, the Cyrtodactylus khasiensis found primarily in the Khasi Hills of Meghalaya. Photographs I had taken of the urban bent-toed from the Basistha area of Guwahati in 2011, when compared with other species, made global experts realise it was a different species,” Mr. Purkayastha told The Hindu. Though the urban bent-toed gecko falls within the khasiensis group, it differs from other members of this group in mitochondrial sequence data as well as aspects of morphology such as the number and arrangement of certain pores in males, the number of mid-ventral scales and colour pattern.

The study on the urban bent-toed gecko also provided additional information on the Guwahati bent-toed gecko, the first of the two Cyrtodactylus endemic to the areas covered by the city and the fourth from Assam.

12th from Northeast

Guwahati is home to 26 species of amphibians, 57 species of reptiles, 214 species of birds and 36 species of mammals. The city provides that edge for urban biodiversity to thrive because it encompasses 18 hills, eight reserve forests, two wildlife sanctuaries and a Ramsar site besides the Brahmaputra river.
