Page 1 and Marvin E. Braasch 2 The presence of an undescribed species of FAheostoma (sub-genus Catonotus) in the Duck River system of Tennessee has been known since the 1930's. Recently this darter has been referred to as the "Duck River relative of EtJieostoma virgatum" or as the "Duck River barcheek darter." This darter, described herein, is limited in distribution to the tributaries of the upper Duck River in Redford and Marshall counties, Tennessee. EtJieostoma virgatum is distrib-uted disjunctly in three portions of the Cumberland River system. The characters examined and methods of analysis employed for the following descriptions were the same as those used by Page and Braasch (1976).
