N1 - Funding Information:
This study was performed as part of Molecular Sequencing and Systematics, an upper-level course offered through the Department of Ecology and Evolutionary Biology at KU. Partial support for this work was provided by an IMSD grant from the NIH Minority Opportunities in Research Program (NIGMS; NIH 1 R25 GM 62232). We especially thank Drs. James Orr and Leonard Kristhalka for inviting us to offer this course and EEB and the Biodiversity Research Center and Natural History Museum at KU for obtaining funding to provide necessary equipment and to cover laboratory expenses.

N2 - We infer the phylogenetic relationships of finescale shiners of the genus Lythrurus, a group of 11 species of freshwater minnows widely distributed in eastern North America, using DNA sequences from the ND2 (1047 bp), ATPase8 and 6 (823 bp), and ND3 (421 bp) mitochondrial protein-coding genes. The topologies resulting from maximum parsimony, Bayesian, and maximum likelihood tree building methods are broadly congruent, with two distinct clades within the genus: the L. umbratilis clade (L. umbratilis + L. lirus + (L. fasciolaris + (L. ardens, L. matutinus))) and the L. bellus clade (L. fumeus + L. snelsoni + (L. roseipinnis + (L. atrapiculus + (L. bellus, L. algenotus)))). Support is weak at the base of several clades, but strongly supported nodes differ significantly from prior investigations. In particular, our results confirm and extend earlier studies recovering two clades within Lythrurus corresponding to groups with largely "northern" and "southern" geographic distributions. Several species in this genus are listed in the United States as threatened or of special concern due to habitat degradation or limited geographic ranges. In this study, populations assigned to L. roseipinnis show significant genetic divergence suggesting that there is greater genetic diversity within this species than its current taxonomy reflects. A full accounting of the biodiversity of the genus awaits further study.
