Vine snakes in the Western Ghats: In a revolutionary moment for reptilian taxonomy, researchers found that the commonly occurring green vine snake (Ahaetulla nasuta) from the Western Ghats was actually four distinct species. Clockwise from top left, they are the Northern Western Ghats vine snake (Ahaetulla borealis), Farnsworth’s vine snake (Ahaetulla farnsworthi), Malabar vine snake (Ahaetulla malabarica) and Wall’s vine snake (Ahaetulla isabellina). They look similar but are separated by ecological and geographical barriers. (Photo courtesy Ashok Kumar Mallik)

A frog from the Eastern Ghats: The Raorchestes kollimalai is a new species of bush frog from the understudied Eastern Ghats. Apart from its physical features and geographic data, the clinching factor in identifying it was call-acoustics. Frogs are active on torrential monsoon nights, and while in the field on one such night, the scientists found that one of the calls they were hearing was different and previously undescribed. The frog has been named for the Kolli hills of Tamil Nadu, where it was first found.(Photo courtesy Zeeshan Mirza)

New species of moray eel from the Andaman and Nicobar Islands: A new white-spotted moray eel (Gymnothorax aurocephalus) was discovered off the Swaraj Deep islands. Moray eels, including the new find, are almost exclusively marine, and characterized by irregular white spots on their body. Unlike the others in its genus, the G. aurocephalus is a chocolate brown with golden skin shadings. It also has pointed and serrated jaw teeth.  (Photo courtesy K K Bineesh)

Sea slugs from Maharashtra & Gujarat: The Cratena poshitraensis (images A and B) has been named after the Poshitra region in Gujarat and the Cratena pawarshindeorum (images C and D), which was found on the rocky intertidal shores of Uran and spreads across the shores of Mumbai, was named after Rajendra Pawar and Vishwas Shinde, researchers from the Bombay Natural History Society (BNHS), for their contributions to the study of sea slugs.

Barklice from the Western Ghats: Of the 400-odd discoveries made last year, one belonged to the order of microscopic insects (booklice, barkflies, etc). The Soa papanasam is a species of barklice (named so because they typically feed on algae and lichen on trees) found in the Kalakkad Mundanthurai Tiger Reserve and Meghamalai Wildlife Sanctuary in Tamil Nadu. This is the first species of the genus Soa described from India.  (Photo courtesy KA Subramanian)
