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 releases.

Status: Reported in Connecticut; no recent collections known (Whitworth 1996). Reported from Delaware drainage.

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: According to Jenkins and Burkhead (1994), the population reported by Cooper (1983) in the Delaware drainage, Pennsylvania, may be introduced. Gilbert (personal communication) also agrees that it probably was introduced, for reasons discussed in Gilbert (1980). Schmidt (1986) did not list this species as occurring in the Delaware drainage and makes no mention of a possible introduction there.
