[2] This snake was first described by Thomas Nelson Annandale (the first director of the Zoological Survey of India) in 1906.

There has long been taxonomic confusion due to the sexually dimorphic coloring of species, with the green males resembling the long-nosed whip snake (Ahaetulla nasuta), while females are brown in color and physically resemble the brown-speckled whipsnake (Ahaetulla pulverulenta).

[4] It is limited to India (Odisha, West Bengal, Jharkhand, Bihar) and Bangladesh.

[2] This species is sexually dichromatic, with the males being green, while females are brown in color.

It has rear fangs typical of the Ahaetulla genus, and a long prominent appendage at the tip of its snout, covered by many small scales above, which is unique among related species.
