the Ozarks eastward throughout much of the Appalachian region and 
includes numerous caves (Hubbell 1936, Holsinger and Peck 1971, Peck 
and Lewis 1978). No attempt has been made to collect Ceuthophilus 
systematically from caves in Virginia and east Tennessee; thus its 
occurrence in study-area caves is more common than indicated by the 
few records cited below. 
In comparison with Ceuthophilus , Euhadenoecus , the other genus 
found in regional caves, is light brown in color, lacks conspicuous 
banding, and has a more slender body with longer legs. Euhadenoecus 
puteanus , a threshold trogloxene like C. gracilipes, is widely distributed 
throughout much of the Appalachian region and a part of the Interior 
Low Plateaus. It is recorded from numerous caves and epigean localities, 
many of these in Virginia and east Tennessee (see Hubbell and Norton 
1978). Euhadenoecus fragilis, in contrast to E. puteanus , is a habitual 
trogloxene, or a troglophile under some circumstances. It is lightly 
pigmented, has attenuated legs (Fig. 32B), and is closely associated with 
the cave environment. It breeds in caves and commonly occurs far from 
entrance zones. The range of this species (Fig. 27) extends from Bath 
County, Va., and southern Randolph County, W.Va., southwestward to 
Claiborne County, Tenn., and includes Pine Mountain in southeastern 
Kentucky; the majority of locality records are from caves (see Hubbell 
and Norton 1978). Although common in the Clinch and Powell valleys, 
it is to date unrecorded from the Holston Valley. In addition to the 
localities listed below, we have made many unrecorded sightings of E. 
fragilis in southwestern Virginia caves.
