Crosbycus goodnighti (Nemastomatidae) is reported from Fountain 
Cave in Augusta County. According to W. A. Shear (in litt.), the 
description and figure of this species by Roewer (1951) apply to the 
juvenile of a European nemastomatid, and the identity of this taxon is 
therefore questionable.

to collect them systematically.

Subclass Araneae 
The cave spider fauna of Virginia and east Tennessee is quite 
diverse and comprises 13 families, 31 genera, and approximately 38 
species. However, about one-third of the species recorded are accidentals 
or only marginal trogloxenes and contribute very little to the fauna of 
most caves. The remaining species are divided roughly equally between 
trogloxenes/ trogophiles and troglobites. As noted in the list below, 
most of the trogloxenic and trogophilic spiders associated with caves in 
the study area are also recorded from caves in other parts of the eastern 
and southeastern United States as well as from epigean localities. Many 
species are associated with ground litter and similar habitats at the 
surface. In caves, spiders occupy a number of microhabitats and are 
often found around decomposing wood, in the damp recesses of passage 
walls and ceilings, and sometimes beneath rocks near the banks of 
streams. 
Troglobitic spiders in the study area, as well as in most of the 
eastern United States, belong to the families Linyphiidae and Nesticidae. 
Five species of linyphiids have been recorded, all of which are presumably
