Description:
False and Ouachita Map Turtles can be differentiated from each other by the shape and placement of the markings on their head. There is not currently a method to differentiate them by the shape or coloration of their shell. The two species are grouped together into one account because many of the specimens in collections are only shells.
Both species have a low keeled ridge along the top of the carapace (top shell) that has rear-pointing projections (knobs) toward the head. Their head color is dark brown with many, cream to yellow lines and spots of various sizes and thicknesses. The carapace is brown to green with thin light colored markings, that fade on larger turtles. Specimens often have 2-4 dark diffuse-edged spots along the side. The entire carapace is sometimes obfuscated by algae growing on the shell. The plastron (lower shell) is cream to light yellow with occasional paired diffuse-edged dark spots. Their legs and tail are brown with cream to yellow stripes running down them.
The range of head markings on the False Map Turtle (G. pseudogeographica) is quite variable. Typically, they have prominent (yet thin) yellow line behind each eye on the top of the head. The inside of each line tapers toward the mid-line of the head and turns toward the neck. In many specimens, the bar behind the eye will form a thin crescent around the back of the eye on the side of the head.
The head markings of the Ouachita Map Turtle (G. ouachitensis) are less variable and consists of a large squarish blotch behind each eye on the top of the head, which tapers abruptly toward the mid-line and then turns toward the neck. They typically possess a prominent yellow spot between their eye and mouth on each side of the head, and another below it on the lower jaw. In a few specimens, the large blotch behind the eyes may connect with the spot below the eye, to form a thicker jagged 'angled' crescent.
Adults normally 90-200 mm (3½-8 inches) in carapace length; largest specimen from Kansas: female (KU Color Slide 11236) from Riley County with a carapace length of 256 mm (10 inches) collected by Steven Seitz and Robert Seitz on 2 August 1996; maximum carapace length throughout range: 10 5/8 inches (Conant and Collins, 1998).

Distribution:
The False Map Turtle (G. pseudogeographica) is known from the following river basins in Kansas: Kansas (Kansas [including the Solomon to Glen Elder Lake and Saline to Wilson Lake], the entire lengths of the Walnut, Caney, Verdigris, Fall, Neosho, and Spring rivers, and the upper Marais des Cygnes River). They have not been reported from much of the Marais des Cygnes River basin in Kansas.
The Ouachita Map Turtle (G. ouachitensis) is known from the following river basins in Kansas; Marais des Cygnes, Spring, Neosho, Verdigris, Fall, Walnut, and Arkansas/Pawnee [to Pawnee County]. There are localized populations along the Kansas River to Geary County.
These turtles are found in the rivers and streams of eastern Kansas, making it out onto the plains along the Arkansas, Pawnee, Saline, Smoky Hill, and Solomon Rivers. 
Localities mapped in Collins (1994) from Coffey County (KU 3287-8) are too imprecise to map. Pleistocene fossils are known from Meade County. This record lies well west of the currently recognized distribution of this species.

Natural History:
False/Ouachita Map Turtles occur in a wide variety of aquatic habitats, including lakes, rivers, streams, and ponds. Predominantly eat snails, mussels, and aquatic insects, although females will also eat a considerable amount of aquatic vegetation.
Can often be observed from bridges over the streams where they occur. Like other map turtles, the males are much smaller than the females.

Occurrence Activity:
Remarks:
First reported in Kansas by Hallowell (1856). The earliest existing specimen is from 1911 (KU 3297).
Many of the available specimens from Kansas do not permit examination of the skull or they exist as a shell only. Consequently, we cannot with certainty assign any particular specimen to a species and have elected instead, to retain the complex which recognizes that separate, but cryptic, species do exist. Genetic analyses coupled with additional morphological examination are needed to adequately address the distribution and status of all three species of this complex in the state.
