Etheostomatinae

Etheostoma is a genus of small freshwater fish in the family Percidae, and within the subfamily Etheostomatinae, native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.

Ammocrypta is a genus of freshwater ray-finned fish, commonly known as the sand darters, which is classified in the subfamily Etheostomatinae, part of the family Percidae which also includes the perches, ruffes and pikeperches. The species in the genus occur in eastern North America in Canada and the continental United States.

Percina is a genus of small freshwater ray-finned fish belonging to the subfamily Etheostomatinae, which is part of the family Percidae. The Percidae family also includes the perches, ruffes and pikeperches from North America. Along with similar fishes in other genera, members of Percina are commonly known as "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of Percina displaying vertical bars on their flanks are called logperches.

Crystallaria is a genus of freshwater ray-finned fish which is classified in the subfamily Etheostomatinae, commonly known as the darters, part of the family Percidae which also includes the perches, ruffes and pikeperches. They are found in the Mississippi River basin from Ohio to Minnesota and in southern Mississippi, northern Louisiana, and southeastern Oklahoma, and on the Gulf Slope of Escambia, Mobile Bay, and the Pearl River drainages. They have now been extirpated from Ohio, Kentucky, Indiana, and Illinois.

Nothonotus is a genus or subgenus of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the southeastern United States. First proposed as a sub-genus of Etheostoma in 1988, there is still debate regarding the appropriate taxonomic rank of Nothonotus in the literature. Darter species comprise more than 180 of the Percidae taxa.
