Taxonomy:  Graptemys geographica is a monotypic species with no recognized subspecies (Iverson et al. 2012). 

Distribution:  The Northern Map Turtle is found throughout Middle and East Tennessee in streams of the Tennessee and Cumberland River drainage basins.  One questionable literature record (see below) exists from the Reelfoot Lake area.

Questionable and/or Erroneous Records: Wells et al. (1974) reported collecting several (exact number not given) females from “the Reelfoot Lake area of West Tennessee” for use in a laboratory study to determine the effects of aldrin and dieldrin on the ATPase system.  Apparently the remains of these animals were discarded following the study, thus no voucher material exist.  This record, though not being disputed, must be considered problematic until verified with voucher specimens or photographs of the species from this part of Tennessee.

Conservation Status: None.
