This species complex occurs throughout most of the Ozark Highlands, Boston Mountains, and Arkansas Valley north of the Arkansas River. The North Fork and White Rivers may approximate the northeastern range boundary, but further work is needed to examine and confirm identifications for a number of records from east of these rivers. Questionable records come from the vicinity of Swifton, northern Jackson County (ASUMZ 21502 from 1994), and Imboden, Lawrence County (AMNH 16102 from 1922, ASUMZ 10426-10436 from 1988, and FMNH 91035 from 1928).
