Rhinichthys

Rhinichthys, known as the riffle daces, is a genus of freshwater fish in the carp family of the order Cypriniformes. The type species is Rhinichthys atratulus, the blacknose dace. Rhinichthys species range throughout North America. The genus contains eight living species, one of which is considered Vulnerable. It also includes the extinct Las Vegas dace, which was only first described in 1984 and had disappeared by 1986. The cheat minnow, a natural hybrid of the longnose dace and the river chub, was formerly placed in this genus, but is now valid under Pararhinichthys. The riffle daces are a basal lineage in an insufficiently resolved clade of American Leuciscinae. Such a group had been proposed on anatomical evidence, and was verified using mtDNA 12S rRNA sequences.
