Notropis is a genus of freshwater ray-finned fish in the family Leuciscidae, the shiners, daces and minnows.[1] They are known commonly as eastern shiners.[2] They are native to North America, and are one of the continent's most speciose genera.[3][4]

A 1997 phylogenetic analysis placed the genus in a clade with Campostoma, Cyprinella, Phenacobius, Platygobio and Rhinichthys.[5] The systematics of the genus is still unclear. It has not been confirmed to be monophyletic. While it has been divided into several subgenera and species groups, the relationships between the taxa are not yet understood.[6]

Characteristics

[edit]

Members of the genus Notropis have eight dorsal rays and have no barbels. Scales for most species are not usually that much taller than they are wide. Their scales are usually not diamond shaped.

Their intestines are short and usually have one loop at the front.[4]

Species

[edit]

These are the currently recognized species in this genus:[7]

Notropis girardi
Notropis maculatus
Notropis stilbius
