This species is represented by 2 records from 1 source: 0 museum (), 0 literature (), 0 research (), and 2 observation (), with # additional Trauth et al. (2004) locality points remaining unsourced (). It has been museum vouchered for 0 of 75 counties (), with 1 additional county having other forms of reported occurrence (). Years of collection range from 2013 to 2014.

This species was first reported from Arkansas in 2013 (M. Morris and K. G. Roberts, unpublished data), based on a gravid female found within the city limits of Bentonville, Benton County. Another specimen from 2014 was taken at a different locality, but within the same general area. Residents at both localities claimed to have previously observed this species, lending legitimacy to the presence of an established population. Further occurrence could be expected along the western border of the state, based on a record from southeastern Cherokee County, Oklahoma (Sievert and Taggart, 2020), and in the southwest corner of the state, given it has been recorded from all bordering Texas counties in this region (Dixon, 2013). However, the species has not been reported from Louisiana (Boundy and Carr, 2017; Powell et al., 2016). A record traced to the Ozark Biological Laboratory, Imboden, Lawrence County (CUMV 1146 from 1929; not shown), is clearly in error, with the provided locality likely in reference to the institution source rather than collection site.
