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.

Means of Introduction: Unknown; possible bait bucket release.

Status: Based on information given in Stauffer et al. (1995), this species is apparently established, possibly introduced, in Monongahela drainage, 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: In their discussion of the species, Stauffer et al. (1995) reported that there is one record of E. laurae from the Tygart Valley River, a Monongahela River tributary, which they indicated was the only record of the species in West Virginia outside of the New and lower Kanawha drainages. However, only in their table on page 14 of their book did Stauffer et al. (1995) hint that the species may have been introduced to the Monongahela drainage.
