This species has a questionable occurrence record from Arkansas. As currently attributed, it ranges east of the Mississippi River into Tennessee, with its sister taxon, T. triunguis, continuing southeastward south of Tennessee (Powell et al., 2016). An observation record from near Helena-West Helena, Phillips County, is currently attributed as a likely transplant (iNat 16589014 from 2016).
Addendum (2022): Since publication, additional corroborating evidence of established occurrence comes from the vicinity of Helena-West Helena, possibly as a result of transplantation.
