Eastern blacknose dace is a species of ray-finned fish in the genus Rhinichthys. Its name originates from the Old French word "dars" which is the nominative form of the word "dart" in reference to their swimming pattern. The western blacknose dace formerly was considered conspecific. While morphologically the two species are not significantly different, they are allopatric. The eastern blacknose dace is found across the southeast portion of Canada and down along the United States' east coast. It is dark brown to olive on its dorsal surface and silvery white below, the two shades separated by the darkly pigmented lateral line. In the breeding season, males develop darker pigmentation and an orange lateral line. Blacknose dace live in rocky streams and rivers where they feed upon small invertebrates and microscopic biological matter and provide forage for larger fish.
Umpqua dace is a species of ray-finned fish in the genus Rhinichthys. It is endemic to the United States where it inhabits the Umpqua River drainage in Oregon.

Western blacknose dace is a common species of ray-finned fish belonging to the family Cyprinidae and the genus Rhinichthys. Western blacknose dace have tan to dark brown backs, lighter sides, and cream colored undersides. Dark blotches are sporadically scattered across their sides and backs. A distinctive dark colored mid-lateral stripe from the tip of the snout to the caudal peduncle is present. The snout is relatively long and they have a slightly sub-terminal mouth. The stripe is dark brown in females and is a rusty pink color in males during spawning season. The lateral stripe is more pronounced and the caudal spot is present in juveniles. Similar to other species of dace the western blacknose dace give the illusion of having no scales but in actuality the scales are so small they are hard to see. Western blacknose dace are typically 2-3 inches long but can grow to as long as 4 inches.
