North America: Historically in several tributaries of Tennessee River in Virginia, North Carolina, Tennessee, Georgia to Alabama, USA; now present only in Little Tennessee River in North Carolina, Buffalo and Emory river in Tennessee, and Holston River in Virginia and Tennessee, USA.
北美洲: 在歷史上在許多的田納西河流域, 從維吉尼亞，北卡羅萊那州，田納西州, 到阿拉巴馬州的喬治亞州。 最近曾經觀察只在小田納西河，北卡羅萊那州中; Duck 河與 Emory 河, 田納西州; 而且霍爾斯頓河的北方分支，維吉尼亞與美國田納西州。

Maturity: Lm ?, range 6 - ? cm
Max length : 11.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 86798); common length : 7.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 4 年 (Ref. 12193)
Found in rocky riffles and runs of clean small to medium rivers (Ref. 5723, 86798). Juveniles are associated with small gravel substrates and moderate current, while adults are encountered in swift currents and boulder substrates. Feed on aquatic insects, predominated by midge, blackfly, and caddisfly larvae (Ref. 10294).
