Acrossocheilus longipinnis is a species of cyprinid fish from the Pearl River basin in southern China. It has sometimes been included as a subspecies of A. iridescens, but recent authorities recognize them as separate species. M. longipinnis reaches at least in length. Juveniles are pale yellowish with 5âÂÂ6 narrow dark bars, but in adults (over long) the dark bars are broad.
