This occurs in northeastern and Atlantic coastal regions, locally in the Blue Ridge but rarely in the Ohio River watershed. In Ky. it is known only from Pine Mt. in HARL, where discovered by Kearney (1893) and rediscovered a century later by M. Evans (KSNPC). The species might also be expected in western regions of the state, since it is known from s. Ohio, s. Ind. and s. Ill. (K); Short (1840) reported it from Harrison Co., Ind.
