Genus Antriadesmus Loomis 
Fig. 3 
Three species of this genus are known from the Appalachian re- 
gion. All are about 6.5 mm long and can be separated only by the 
form of the male gonopods, and for the present, the collection lo- 
cality. Antriadesmus fragilis Loomis (Fig. 3) was described from 
females (Loomis, 1953) collected in White’s Cave, Mammoth Cave 
National Park, Kentucky; subsequently Loomis (i960) illustrated 
the male gonopod, and noted that the species occurs nowhere else in 
the entire Mammoth Cave complex. Causey (1959b) described A. 
mollis from Cumberland Caverns, Warren Co., Tennessee, and A. 
debilis from Walker Spring Cave, Wayne Co., Tennessee.
