Explanation:

A new species of old world monkey recorded from Arunachal Pradesh has been named after a strategic mountain pass at 13,700 ft above sea level.

• Sela macaque (Macaca selai), the new-to-science primate was identified and analysed by a team of experts from the Zoological Survey of India (ZSI) and the University of Calcutta.
• Their study has been published in the latest edition of Molecular Phylogenetics and Evolution. Phylogenetics relate to the evolutionary development and diversification of a species or group of organisms.
• The phylogenetic analysis revealed that the Sela macaque was geographically separated from the Arunachal macaque (Macaca munzala) of Tawang district by Sela.
• This mountain pass acted as a barrier by restricting the migration of individuals of these two species for approximately two million years, the study said.
• Sela is situated between Dirang and Tawang towns in western Arunachal Pradesh.
• The study says the Sela macaque has a tail longer than the Tibetan macaque, Assamese macaque, Arunachal macaque and the white-cheeked macaque but shorter than the bonnet macaque and toque macaque.
• Sela macaque belongs to the sinica species-group of Macaca, but it differs from all other members of thisgroup through attributes such as brown collar hair and muzzle, and the absence of chin whiskers, the study says.

Hence both statements are correct.
