Semotilus is the genus of creek chubs, ray-finned fish in the family Leuciscidae. The term "creek chub" is sometimes used for individual species, particularly the common creek chub, S. atromaculatus. The creek chub species of minnows can grow from . They can be found in the United States and Canada in any small stream or creek. They hide under small rocks for protection. They have a small black spot on the dorsal fin for easy identification.

Lepidomeda is a genus of freshwater ray-finned fishes belonging to the family Leuciscidae, which includes the daces, Eurasian minnows and related species. The fishes in this genus are commonly known as the spinedaces, found in western North America. Of the known species, one is extinct and two are threatened. They appear to be fairly close to the spikedaces in the genus Meda, but the phylogeny and indeed the validity of the proposed "plagopterin" clade is insufficiently resolved.

Margariscus, known as the pearl daces, is a genus of leusiscid fishes found in North America. There are currently two recognized species in this genus. Margariscus comes from the Greek word margariskos, meaning pearl.
