The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Ecology: Inhabits medium to large streams with moderate current, over sandy areas where it will bury itself leaving only the eyes and mouth visible (Etnier and Starnes 1993).

Means of Introduction: These fish likely gained access to the Wolf system via the Wisconsin-Fox Canal (Becker 1983).  Mechanism of transport to West Virginia is unknown.

Status: Established in Wisconsin and West Virginia.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: Voucher specimens: Michigan (UMMZ 232910), Wisconsin (UWSP 1155), West Virginia (WVWR 771, 785, 1063, 1117, 1185).
