Highlights We investigated phylogeny and diversification rates in the fish genus Nocomis. This genus diverged from its sister taxon in the late Miocene, MYA. Genetic data reveal cryptic diversity within Nocomis leptocephalus. Climate change likely played a significant role in diversification of Nocomis leptocephalus. Patterns of speciation in this group reinforce faunistic and geologic. 1. Introduction. The North American genus Nocomis includes nine formally described taxa of medium sized (up to about 20 cm, SL) cyprinid species occurring primarily in clear, gravel-bottomed upland streams. Three morphologically defined species groups are traditionally recognized (Lachner and Jenkins, a, Lachner and Jenkins, b, Lachner and Wiley, ): the N. 1.

The nominal North American cyprinid fish Notropis henryi interpreted as an intergeneric hybrid, Clinostomus funduloides X Nocomis leptocephalus. Copeia, (1): – Gilbert, C.R. Designation of a neotype for the kyphosid fish Kyphosus sectatrix (Linnaeus, ). Zootaxa (2): – Species can be monotypic or polytypic depending on the classification of the species into subspecies. The Hyacinth macaw is an example of a Monotypic species as it is not divided into any subspecies. In scientific terms, a species is a group of living organisms that belong to the lowest taxonomic level of the biological classification hierarchy. We examined context dependency in a reproductive mutualism between two stream fish species: mound nest‐building bluehead chub Nocomis leptocephalus and mountain redbelly dace Chrosomus oreas, which often uses N. leptocephalus nests for spawning. We hypothesized that increased predator density and decreased substrate availability would increase the propensity of C. oreas to associate with N.
