Notropis is a genus of freshwater Actinopterygii in the family Leuciscidae, the shiners, daces and minnows.[ Notropis Système canadien d’information sur la biodiversité (SCIB)] They are native to North America, and are one of the continent's most speciose genera.[McAllister, C.T., Layher, W.G., Robison, H.W. & Buchanan, T.M. (2009): New Distribution Records for Three Species of Notropis (Cypriniformes: Cyprinidae) from Large Rivers of Arkansas. Journal of the Arkansas Academy of Science, 63: 192-194.]
A 1997 phylogenetics placed the genus in a clade with Campostoma, Cyprinella, Phenacobius, Platygobio and Rhinichthys.[Simons, A.M. & Mayden, R. (1997): Phylogenetic Relationships of the Creek Chubs and the Spine-Fins: an Enigmatic Group of North American Cyprinid Fishes (Actinopterygii: Cyprinidae). Cladistics, 13 (3): 187-205.] The systematics of the genus is still unclear. It has not been confirmed to be monophyly. While it has been divided into several subgenera and species groups, the relationships between the taxa are not yet understood.[Cashner, M.F., Piller, K.R. & Bart, H.L. (2011): Phylogenetic relationships of the North American cyprinid subgenus Hydrophlox. Molecular Phylogenetics and Evolution, 59 (3): 725-735.]
Characteristics
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.
