This uncommon species has a very spotty distribution record in the Mississippi Alluvial Plain, South Central Plains, and Arkansas Valley. The unusual habits of this species, such as long aestivation retreats, and preferred habitat of temporally-flooded edge backwaters make sampling challenging. Several records from the Missouri Bootheel (Daniel and Edmond, 2020) suggest a wider distribution in the northeast corner of the state. A 2016 record from Miller County illustrates the need for further surveys across the South Central Plains. Trauth et al. (2004) plotted a number of localities along the western Arkansas Valley and scattered in the Ouachita Mountains which remain unsourced.
