PHYLUM ARTHROPODA: SUBPHYLUM CRUSTACEA 
A significant number of the species recorded from caves in Virginia 
and eastern Tennessee are crustaceans and include copepods, amphipods, 
isopods, crayfishes, and possibly ostracods. The vast majority, however, 
are amphipods and isopods, both of which are frequently well represented 
in aquatic cave communities. 
Class Copepoda 
Cave copepods are very poorly known from the study area and 
only a single species has been recorded to date. However, as pointed out 
earlier, no attempt was made to sample microscopic cave faunas, and 
the lack of data on tiny crustaceans such as copepods and ostracods is 
to be expected. 
Order Cyclopoida 
Family Cyclopidae 
Cyclops vernalis Fischer (TX) 
Virginia. — Tazewell Co.: Hugh Young Cave. 
Comments. — Extremely variable and widespread species sometimes 
recorded from caves (e.g., in Georgia, Kentucky, New Mexico, 
Texas) (see Barr 1967a, Reddell 1965, Barr and Reddell 1967, 
Holsinger and Peck 1971).
