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: Probable bait bucket introduction into the Gasconade River during the 1950s and subsequent dispersal (Pflieger 1997).

Status: Established in parts of Missouri outside its native range.

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: No records exist for this species in tributaries of the Missouri River before the 1950s. During the last 30 years it has become abundant and widespread in the Gasconade River drainage and other tributaries of the lower Missouri (Pflieger 1997).
