A single male each was reported by Harp and Harp (1996 ) from Clark County, Arkansas, and by Bick and Bick (1957 ) from Latimer County, Oklahoma (previously reported by Bird (1932a ) as Epitheca canis McLachlan, Beaverpond Baskettail). This species has also only been documented from Houston County within Texas.
