Probarbinae
Probarbinae is a subfamily of freshwater ray-finned fishes belonging to the family Cyprinidae, which includes the carps, barbs and related fishes. The fishes in this subfamily are found in tropical Asia. Fish of the two genera reach large sizes, with all species recorded to exceed in length, with Catlocarpio often being reputed to be the largest cyprinid known to exist, supposedly reaching and in size. The subfamily, originally described as a tribe, is distinguished from other cyprinids by a combination of traits: tetraploidy, a single row of pharyngeal teeth with 4 on each side, the last simple anal-fin ray being segmented and flexible, and scales which cover most of the body.
