Etymology
The Latin epithet "arunachalensis" in Pinus arunachalensis was named for the state of Arunachal Pradesh, India.{{cn|date=June 2023}}
It was originally listed under the now regarded synonym: Pinus parva (Pinus wallichiana var. parva), but the same scientific name was already taken for a fossil pine species, hence it was renamed and revised as such.
