𝐺𝑎𝑟𝑟𝑎 ℎ𝑒𝑥𝑎𝑔𝑜𝑛𝑎𝑟𝑜𝑠𝑡𝑟𝑖𝑠, a new member of the ‘proboscis species group’, is described from the Chakpi River of Chindwin basin in Manipur, India.
The new species is distinguished by the following combination of characters: a prominent hexagon-shaped unilobed proboscis with five large-sized conical tubercles on anterior margin, and three or four medium-sized conical tubercles on anteroventral region; transverse lobe with 13−35 small- to medium-sized conical tubercles; lateral surface of snout swollen with 8−18 small- to medium-sized conical tubercles; 31−32 lateral-line scales including three pored scales on caudal fin; and a large arch-shaped black spot on each side of opercle, immediately anterior to upper angle of gill opening.
The taxonomic status of several species of 𝐺𝑎𝑟𝑟𝑎 from Arunachal Pradesh and Mizoram, is reviewed and accordingly 𝐺𝑎𝑟𝑟𝑎 𝑚𝑖𝑛𝑖𝑚𝑢𝑠 is considered as a junior synonym of 𝐺. 𝑞𝑢𝑎𝑑𝑟𝑎𝑡𝑖𝑟𝑜𝑠𝑡𝑟𝑖𝑠; 𝐺. 𝑛𝑖𝑔𝑟𝑖𝑐𝑎𝑢𝑑𝑎 as a junior synonym of 𝐺. 𝑎𝑟𝑢𝑛𝑎𝑐ℎ𝑎𝑙𝑒𝑛𝑠𝑖𝑠; 𝐺. 𝑎𝑙𝑡𝑖𝑐𝑎𝑝𝑢𝑡𝑢𝑠 and 𝐺. 𝑘𝑖𝑚𝑖𝑛𝑖 as junior synonyms of 𝐺. 𝑏𝑖𝑟𝑜𝑠𝑡𝑟𝑖𝑠; and 𝐺. 𝑡𝑦𝑎𝑜 as a junior synonym of 𝐺. 𝑟𝑎𝑘ℎ𝑖𝑛𝑖𝑐𝑎.
