FALSE MAP TURTLE
Found in the rivers and streams of eastern Kansas, making it out onto the plains along the Arkansas, Saline, 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.

There is currently some confusion as to the taxonomy of this complex in Kansas. The work of Vogt (1993) represents the most recent and comprehensive assessment of intra- and interpopulation relationships in this complex. He demonstrated that head marking patterns among individuals were highly variable in this complex, and that they could be explained by changes in incubation temperatures within a single brood. He was able to differentiate the Ouachita Map Turtle from the others using detailed statistical analyses of skull and shell characters, and reported individuals of all three forms in Kansas.
Pleistocene fossils are known from Meade County. This record lies well west of the currently recognized distribution of this species.
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.
