It is endemic to Indonesia. his species was described in 1991 by Maurice Kottelat from a type locality of Lake Matano.

Acanthocobitis pavonacea, also known as the spearfin loach, is a species of ray-finned fish belonging to the family Nemacheilidae, the stone loaches. This species is found in the Brahmaputra River ofAssam. This is one of two species in the genus Acanthocobitis, alongside the type species, A. longipinnis. A. longipennis was treated as synonym of this species but in 2021 Maurice Kottelat and Waikhom Vishwanath published a paper that argued that A. longipennis was a valid species and that it was one of two species ofloach in the genus Acanthocobitis, alongside A. pavonacea, with the other species being classified in the genus Paracanthocobitis. This species is the type species of the genus Acanthocobitis.
