Individuals from this region often share characters typical of Tibicen pruinosus & winnemanna. Somewhere in the upper mid-South (Appalachia into the Tennessee River Valley ... west to the Mississippi River), there seems to be a break down in the delineating characters between T. pruinosus and T. winnemanna ... detailed studies of these populations are needed to untangle the relationships.

NOTE: Both "pruinosus" and "winnemanna" may be encountered in the literature as belonging to the "same species" (=subspecies of T. pruinosus) or as distinct taxa. A third taxon, T. latifasciatus, may also be considered a subspecies of pruinosus in some lit.; however, latifasciatus is by far the most distinct member of this complex.
