This species is represented by 574 records from 23 sources: 526 museum (
), 7 literature (
), 0 research (
), and 23 observation (
), with 18 additional Trauth et al. (2004) locality points remaining unsourced (
). It has been museum vouchered for 15 of 75 counties (), with 3 additional counties having other forms of reported occurrence (). Years of collection range from 1932 to present.
This species occurs throughout much of the Ozark Highlands and Boston Mountains. A questionable record from Ft. Chaffee, Sebastian County (OMNH 38398 from 1992), is almost certainly a mistake in attribution, as this species is not known to occur south of the Arkansas River.
