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.

Exoglossum maxillingua (Lesueur, 1817)

Common name: Cutlip Minnow

Synonyms and Other Names: Exoglossum annulatum Rafinesque, 1818; E. lesurianum Rafinesque, 1818; E. nigrescens Rafinesque, 1818; E. vittatum Rafinesque, 1818.

Taxonomy: available through www.itis.govITIS logo

Identification: Smith (1985); Page and Burr (1991); Jenkins and Burkhead (1994). Exoglossum be distinguished from most other North American cyprinids by the presence of a central bony plate flanked by fleshy lobes on the lower jaw. Exoglossum maxillingua can be distinguished from the Tonguetied Minnow E. laurae by the size and distinctiveness of the fleshy lobes on the lower jaw (much larger and distinct in E. maxillingua) and the absence of barbels at the corner of the mouth (present in E. laurae).

Size: 16 cm.

Native Range: Atlantic Slope from St. Lawrence River drainage, Quebec, to upper Roanoke River, North Carolina (absent in Connecticut River and other rivers in Northeast); Lake Ontario drainage, Ontario and New York (Page and Burr 1991).

Means of Introduction: Probable bait bucket release. The first records of this species (and hybrids with E. laurae) in the New drainage are from 1956 from the Walker Creek system, a heavily fished area (Jenkins and Burkhead 1994).

Status: Established in Massachusetts, Virginia, and West Virginia. Reported in Connecticut and Vermont.

Impact of Introduction: Cutlips minnows in the New drainage are known to hybridize with the Tonguetied Minnow E. laurae (Jenkins and Burkhead 1994).

Remarks: In their treatment of this species in the New-Kanawha drainage, Jenkins and Burkhead (1994) listed it as introduced possibly established, whereas Stauffer et al. (1995) listed the species as native, but possibly introduced. Jenkins and Burkhead (1994), citing Smith (1905), reported that the occurrence of E. maxillingua in the Passaic drainage, New Jersey, may be due to dispersal via a canal.
