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.

Status: Established, possibly introduced, in extreme western part of Virginia.  Collected in Connecticut, New Hampshire, North Carolina, and Ohio. 

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: Although Lee et al. (1980 et seq.) suggested that this species was possibly introduced into the upper Tennessee drainage of Virginia, Jenkins and Burkhead (1994) concluded that Clinostomus funduloides was native to that area. Gilbert (personal communication) stated that the species is clearly native to the middle and lower Tennessee River drainage, and he believes there is a good chance that the fish is native to the upper reaches as well. There is also some uncertainty concerning the native versus introduced distribution of this species in other areas. For example, the distribution map of Lee et al. (1980 et seq.) seems to indicate the occurrence of this species in the Delaware drainage (Pennsylvania), an occurrence that seems to be based on a single record. Consequently, Gilbert (personal communication) is suspicious of its natural occurrence there, particularly considering that the fish faunas of the Delaware and Susquehanna drainages are substantially different.
