Disclaimer:

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.

Common name: Highback Chub

Synonyms and Other Names: Notropis hypsinotus (Cope, 1870)

Taxonomy: available through www.itis.gov

Identification: Menhinick (1991), Page and Burr (2011). Generally similar to Yellowfin Shiner (Notropis lutipinnis), but can be distinguished by the presence of a barbel at the corner of the mouth, a strongly arched back, and a dorsal fin origin in front of the pelvic fin origin (Page and Burr 2011).

Size: to 7 cm SL (Page and Burr 2011)

Native Range: Above the Fall Line in the Peedee and Santee basins, including the Broad, Catawba, and Yadkin Rivers (Menhinick 1991; Page and Burr 2011).

Alaska	Hawaii	Puerto Rico & Virgin Islands	Guam Saipan

Means of Introduction: Likely bait bucket introduction.

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: Berendzen et al. (2008) showed that H. hypsinotus should not be included as part of the H. amblop species complex.

Museum voucher specimens: North Carolina (NCSM 53287, 53303, 53319, 53338, uncataloged).
