News: New species of gecko recorded in Pachamalai Hills in Tamilnadu

 

What is in the news?

       A team of researchers have identified a new species of rock dwelling large-bodied gecko from the Pachamalai hills near Gingee in the southern Eastern Ghats in Tamilnadu.

 

Key details of the Species:

About:

       The new species has been named as Hemidactylus pakkamalaiensis, after the hill where it was recorded.

       The gecko measures 104 mm from snout to vent (10.4 cm) and is light brown in color.

 

Species in India:

       The genus Hemidactylus goldfuss has 188 species of which 54 are known from India. Members of this group are primarily known to inhabit gigantic boulders.

       The new species can be easily distinguished from other geckos in the region by its large size and prominent tubercles on the body.

       Of the 54 species recorded from India, as many as nine species are restricted to the Western Ghats, while the rest are distributed throughout peninsular India.

       The species discovered off Gingee now increases the total number of species of Hemidactylus in India to 55.

 

Geographical location in Eastern ghats:

       The Gingee hills are characterized by a significant presence of gigantic rock boulders that provide a suitable micro-habitat for rock-dwelling geckos.

       These hills are unique in this regard, and despite being situated in the drier part of peninsular India, Pakkamalai hill is home to a diverse range of vegetation types, including the distinctive Tropical Dry Evergreen Forests.

       The combination of vegetation and the microhabitats availability likely provided an ambient microclimatic condition that facilitated the diversification of this species.

 

Gecko:

       Geckos are reptiles and are found on all the continents except Antarctica.

       These colorful lizards have adapted to habitats from rainforests, to deserts, to cold mountain slopes.

       Most geckos are nocturnal, which means they are active at night, but day geckos are active during the day and depend on insects, fruits, and flower nectar.

       IUCN:

       Indian Golden Gecko (family Gekkonidae) is native to India (Tamil Nadu, Orissa, Andhra Pradesh).

       It is listed in Schedule 1 of WPA (Wildlife Protection Act).

       IUCN Red List: Least Concern (LC).
