DistributionUSA (primarily in large streams of the Mississippi River drainage from Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kansas, NE Oklahoma, Nebraska, South Dakota, Oklahoma, NE Texas, Louisiana, Arkansas, NW Mississippi, Tennessee, W Kentucky, Indiana, Ohio, Alabama)

Type locality: Not stipulated; from Wabash River, New Harmony, Indiana, U.S.A., according to LeSueur 1827 and "Etats-Unis, Indiana, rivière Wabash, entre MontVernon et Chaumetown (=Shawneetown), c'est-à-dire près du confluent de la Wabash et de l'Ohio" according to Bour and Dubois 1983 (cited after KING & BURKE 1989).

kohnii: USA (Arkansas, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee, Texas)

pseudogeographica: USA (Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, Tennessee, Wisconsin)  
TypesSyntypes: MNHN 9136, 9137, 9146, and 9147; MNHN 9147: designated lectotype by Bour and Dubois 1983. 
CommentSynonymy: Graptemys pseudogeographica kohnii (Baur, 1890) has been raised to species status, but later again synonymized with pseudogeographica (Vogt 1993). CONANT & COLLINS 1991 treat kohnii and pseudogeographica as separate species but point out that their relationships are controversial.

Diet: omnivore.

Habitat: freshwater (lakes, rivers) 
Etymologynot genuine map-like; referring to its resemblance of Graptemys geographica
