Historically, many species of Puntius have been classified in several genera, including Barbus. Despite the reclassifications, the specific epithet remains the same in these – except in cases of homonymies –, as Barbus and Puntius have the same grammatical gender. The closest living relatives of the spotted barbs are the Cyprinion barbs, the Assamese Kingfish (Semiplotus semiplotus), and perhaps the Capoeta barbs. These and the other "typical" barbs and barbels were formerly often separated as subfamily Barbinae, but this group is highly paraphyletic with regards to the Cyprininae and better merged there at least for the largest part (including Puntius). In particular the genus Barbonymus, containing the Tinfoil Barb and its relatives, – for some time included in Puntius – appears to be a kind of carp that has evolved convergently with barbs.
