Common Name: tonguetied minnow
Taxonomy: available through 
Identification:
Smith (1985); Page and Burr (1991); Jenkins and Burkhead (1994).
Size: 16 cm.
Native Range:
Three disjunct areas of upper Ohio River basin; upper Allegheny River drainage, New York and Pennsylvania; upper New River drainage, West Virginia, Virginia, and North Carolina; and Great Miami and Little Miami River systems, Ohio; also in upper Genesee River (Lake Ontario drainage), New York and Pennsylvania (Page and Burr 1991).
Nonindigenous Occurrences: Although the tonguetied minnow is generally regarded as native to the Monongahela system, Ohio River drainage, of West Virginia, Stauffer et al. (1995) indicated its presence in that water body may have been the result of a past introduction.
Means of Introduction: Unknown; possible bait bucket release.
Status: Based on information given in Stauffer et al. (1995), this species is apparently established, possibly introduced, in Monongahela drainage, West Virginia.
Impact of Introduction: Unknown.
Remarks: In their discussion of the species, Stauffer et al. (1995) reported that there is one record of E. laurae from the Tygart Valley River, a Monongahela River tributary, which they indicated was the only record of the species in West Virginia outside of the New and lower Kanawha drainages. However, only in their table on page 14 of their book did Stauffer et al. (1995) hint that the species may have been introduced to the Monongahela drainage.
