Stweard B. Peck


A summary is given of families, genera, species numbers, and state distributions of the obligate subterranean (cave and groundwater) faunas of the contiguous United States and Canada. A total of 425 aquatic and 928 terrestrial species (1353 species in all) is now known. Total genus level diversity is greatest (in descending order) in the states of Texas, Alabama, Kentucky, Tennessee and Virginia. This genus and species richness is vulnerable to a variety of land use and pollution problems.
