Taxonomic CommentsSome references to N. INSIGNIS actually may refer to N. LEPTACANTHUS, N. FLAVUS, N. MIURUS, or especially N. EXILIS (Lee et al. 1980). An undescribed form, the spotted margined madtom, occurs in the Dan River, Virginia; evidently it warrants subspecies status (Matthews, in Burkhead and Jenkins 1991). Populations in the upper Roanoke River and certain other waters formerly were recognized as subspecies ATRORUS, but this taxonomic distinction was not regarded as valid in a 1969 revision of the genus NOTURUS (Taylor 1969). See Grady and LeGrande (1992) for a study of phylogenetic relationships, modes of speciation, and historical biogeography of NOTURUS madtom catfishes. See Lundberg (1992) for a synthesis of recent work on the systematic relationships of ictalurid catfishes.
