According to an Indian media report, this rare snake was first spotted in the Lakhimpur Kheri area of Uttar Pradesh state in 1936 from where it got its scientific name ‘Oligodon kheriensis’.
The suffix ‘kukri’ in its name comes from kukri or curved knife of the Gorkhas as its teeth are curved like the blade of the weapon.
It has been spotted a few times in India's hilly state of Uttarakhand.
