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: Reported from middle Arkansas River 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: In their summary table on fishes of western Mississippi River drainages, Cross et al. (1986) listed this species as introduced to the Middle Arkansas River drainage. That record is apparently based on Burr et al. (1979) who reported Notropis ozarcanus and Campostoma oligolepis from the Illinois River system of the Arkansas drainage. Both were previously known from all Ozark drainages except the Arkansas. Because of the absence of both species from earlier records, Burr et al. (1979) suggested that these fishes were bait introductions, although these researchers could not rule out the possibility of both being native to the Illinois River system. According to Cross et al. (1986), these records have been considered introductions, but the same records may also be evidence of past stream capture. These authors did not note the locality or state and they provided no additional information concerning the introduction. In their drainage map, Cross et al. (1986) showed the middle Arkansas River as including portions of northwestern Arkansas, southwestern Missouri, northeastern Oklahoma, and southeastern Kansas. Robison and Buchanan (1988), also in reference to Burr et al. (1979) stated that the species has been discovered occurring disjunctly in the Illinois River (Arkansas River system). However, Robison and Buchanan did not discuss the possibility of it being introduced to that system. According to Burr (personal communication), there are no voucher specimens to verify this record, and it may be based on a misidentification.
