Redside Shiners
Richardsonius
Richardsonius is a genus of cyprinid fish consisting of two species native to western North America. Commonly known as redside shiners, that term is also used to refer to Richardsonius balteatus specifically. The genus is named after naturalist Sir John Richardson (1787–1865), who described R. balteatus in 1836.
