This species is represented by 323 records from 17 sources: 291 museum (), 0 literature (), 0 research (), and 20 observation (), with 12 additional Trauth et al. (2004) locality points remaining unsourced (). It has been museum vouchered for 13 of 75 counties (), with 6 additional counties having other forms of reported occurrence (). Years of collection range from 1926 to present.
This species occurs in the South Central Plains of southcentral Arkansas. It has been found sympatrically with E. multiplicata complex in the vicinity of Caddo Valley, Clark County (K. J. Irwin, pers. comm.), so specimens from this area warrant close examination. A questionable record from southwestern Sevier County (USNM 545607 from 1951) warrants further examination. Trauth et al. (2004) plotted additional localities near Murfreesboro, Pike County, and well into the Ouachita Mountains near Mount Ida, Montgomery County, both of which are likely based on misidentifications but remain unsourced.
