 Introduction:

• A team of researchers has discovered a new species of the venomous green pit viper in Arunachal Pradesh. Two specimens of these spp have been found. The new species has been discovered in the thick ,evergreen forests of Pakke Tiger Reserve  in Pakke –Kessang district in Arunachal Pradesh during a field expedition in held in July 2019.
• It has been named Trimeresurus salazar after Salazar Slytherin-a fictional character from Harry Potter series of J.K Rowling.
• Pit vipers are venomous snakes with heat-sensing pit organs between the eye and the nostril.
• Arunachal Pradesh belongs to Himalayan Biodiversity Hotspot and shows high degree of heterogeneity in its landscape with elevation ranging from 100m -700m and distinct climate regimes that harbour flora and fauna.

Highlights of the discovery:

• The new spp T.salazar is the fifth variety of reptile to have been discovered in Arunachal Pradesh.
• It  belongs to the genus-Trimeresurus lacepede comprising-‘’chareacterstic venomous serpents with morphologically as well as ecologically diverse spp.’’
• Atleast 48 spp are distributed across East and South -East Asia and of these15 are found in India.
• Before T.salazar, 7 of the fifteen spp. have been already found in  North –East.
• Findings of the discovery have been reported in the paper published by a team of researchers-Zeeshan A Mirza,Harshal Bhonsle, Pushkar Phansalkar,Mandar Sanwant,Gaurang Gowande and Harshil Patel.
• Paper is published in the International Science Journal-“Zoosystematics and Evolution”.
• Researchers come from different organisations- Zeeshan- National Centre for Biological Sciences Bengaluru, Harshal and Mandar from  Bombay Natural History Society Mumbai,Gowande – Pune Fergusson College,Pushkar- Wildlife Institute Of India,Dehradun.
• Discovery funded by -Shripad Halbe of Brihad Bhartiya Samaj and Singinawa Conservation Foundation .
