Masticbarbus is a genus of ray-finned fish in the family Cyprinidae (carps, minnows and allies), native to Vietnam and southern China.Fricke, Ron, Eschmeyer, William N. & van der Laan, Richard (eds.). "Species in the genus Masticbarbus". Catalog of Fishes. California Academy of Sciences. Retrieved 22 May 2026.
Species Masticbarbus was previously a synonym of Acrossocheilus, but has recently been resurrected, and it currently contains the following four species:
Masticbarbus clivosius (Lin, 1935) Masticbarbus iridescens (Nichols & Pope, 1927) Masticbarbus longipinnis (Wu, 1939) Masticbarbus microstoma (Pellegrin & Chevey, 1936)
The type species of Masticbarbus was called Masticbarbus pentafasciatus upon its description; this binomial is now under the synonymy of M. longipinnis (Wu, 1939).
Habitat All but one species in this genus live exclusively in freshwater habitats; the exception is M. iridescens, which can live in both freshwater and brackish environments.
