strate. The fish species found associated with P. tennesseensis include Campostoma 

 anomalum and Semotilus atromaculatus (Starnes & Jenkins 1988, Schilling & Ryon 1993). 

 Diet is not well known. The intestine of some contained mainly organic detritus, algae, 

 and diatoms. Starnes & Jenkins (1988) estimated that diet of the species might be simi- 

 lar to that of P. oreas and cumberlandensis because of the similarity of the intestine in 

 these three species. 



P. tennesseensis may spawn over the nest of gravel-nest-building cyprinids, such as Cam- 

 postoma and Semotilus w hich are normally found with this dace and generally in aggre- 

 gations of eight to more than 100 individuals. The spawning season occurs from late April 

 to middle June (Schilling & Ryon 1993). 



Distribution 



P. tennesseensis is restricted to small streams of the Upper Tennessee River drainage in 

 Virginia and Tennessee (Starnes & Jenkins 1988; Schilling & Ryon 1993). Starnes & Jen- 

 kins (1988: fig. 3) mapped the localities where the dace had been found. 



Etymology 



The epithet "tennesseensis" is a combination of Tennessee and the Latin suffix "-ensis" 

 in reference to the type locality and endemism in the Tennessee River drainage (Starnes & 

 Jenkins 1988).
