This species may occur statewide, outside of high gradient streams of the Interior Highlands. The Graptemys ouachitensis / pseudogeographica complex has historically presented taxonomic challenges and the occasional Arkansas specimen has proven difficult to determine specific assignment. Many localities plotted by Trauth et al. (2004), particularly along the western Arkansas Valley, remain unsourced. An isolated record from a city lake in northwest Arkanasas is currently attributed as a likely transplant. Powell et al. (2016) show a large intergrade zone with the G. p. pseudogeographica subspecies (■) across the northeast corner of the state.
