Arkansas Herpetological Atlas 2019
This species is represented by 544 records from 24 sources: 454 museum (), 0 literature (), 0 research (), and 67 observation (), with 23 additional Trauth et al. (2004) locality points remaining unsourced (). It has been museum vouchered for 53 of 75 counties (), with 3 additional counties having other forms of reported occurrence (). Years of collection range from 1917 to present.
This species has been documented throughout much of the northern half of the state and southwest quarter, with scattered records elsewhere. The large gaps in distribution may be an artifact of undersampling. Recent observations of numerous subadults along portions of the eastern edge of Crowley’s Ridge (K. G. Roberts, pers. obs., 2019) suggest this species likely occurs along the entirety of this ecoregion. An isolated record reported by Trauth et al. (2004) from the vicinity of Monticello, Drew County, remains unsourced.
