Abstract
We present a novel mitogenome assembly of the Redlip Shiner, Notropis chiliticus, and assemblies for the Greenhead Shiner, N. chlorocephalus (Cypriniformes: Leuciscidae). Both are charismatic minnows in the taxonomic group Hydrophlox and are endemic to the eastern United States. The N. chiliticus genome contains 16,711bp and N. chlorocephalus 16,706bp each comprising a total of 13 protein coding genes, 22 tRNAs, two rRNAs, and a control region. Sequence order and genome composition are similar to other Notropis. We provide evidence supporting a monophyletic Hydrophlox, while other phylogenetic relationships within Notropis support convoluted taxonomic revisions throughout the history of the genus.
