Justification: Aborichthys elongatus is found in Arunachal Pradesh and western Bengal; it is not known from intermediate watersheds. At present the species is assessed as Least Concern, given the relatively wide distribution, and the assumption that it is probably present in watersheds between the two known localities. Further taxonomic work is required, and the assessment should be revised given further information.
Aborichthys elongatus is distributed in North Bengal and Arunachal Pradesh in India. Nath and Dey (2000) reported the species to occur in different parts of Arunachal Pradesh, but the distribution is fragmented.

♦ Continuing decline in extent of occurrence (EOO):
♦ Extreme fluctuations in extent of occurrence (EOO):
Aborichthys elongatus is known from hill streams which vary in volume with season. There is a need for improved habitat protection at sites where this species is known to occur. Further survey work is needed to determine whether this species is experiencing a decline or is undergoing natural population fluctuations. In Darjeeling, part of the species currently known range, hill streams are pollutde from agricultural run-off and the there is reported widespread use of poison fishing.
It is also known from Namdapha National Park. There is a need for improved habitat protection at sites where this species is known to occur. Further survey work is needed to determine whether or not this species is experiencing a decline or is undergoing natural population fluctuations.
