ABSTRACT: Samples of the Notropis rubellus complex were localities in Kentucky and Tennessee during the late spring of 1998-2001. Based on nuptial coloration, scale and fin-shape, two taxa were diagnosed and recognized as species Notropis rubellus (Agassiz) occupies upland streams of upstream of the mouth of the Green River and in the drainage above Cumberland Falls. Notropis micropteryx land streams of the Cumberland River drainage downstream Falls and the Tennessee River and Green River drainages. from N. rubellus in having modally fewer circumferential 25-26), modally fewer scales below the lateral line (three red on the dorsum of the head of nuptial males. Green exhibit more mean scales below the lateral line and slightly than other N. micropteryx populations. Support for recognition evolutionary species includes zoogeographic evidence in of morphological characters.
