A recent analysis of cytochrome b sequence data suggested the presence of two distinct lineages of stoneroller (Campostoma anomalum) in West Virginia: one form that occurs throughout most waters of the Ohio and Potomac River basins, and a second that is restricted to the New River basin.

In Michael Sovic and Dr. Kody Kuehnl's study, cytochrome b data are presented for individuals sampled from the upper reaches of Shavers Fork, a tributary of the Cheat River that is geographically proximate to, but not within the New River drainage. Haplotypes observed in the individuals from Shavers Fork are most similar to those from the New River. This result is consistent with the hypothesis of a historical connection between Shavers Fork and waters of the New River basin. In addition, if the two forms are formally recognized taxonomically, these data suggest that the range of the New River form may extend into Shavers Fork, and highlight the need for additional sampling in nearby drainages to better understand the full extent of the distribution of this unique stoneroller lineage in West Virginia.
