P seudanophthalmus insularis Barr, new status 
Pseudanophthalmus tiresias insularis Barr 1959:18. Type locality, Baker 
Station Cave, Davidson Co., TN. 
The type locality is a small stream cave in Silurian limestones of the 
Highland Rim margin north of Nashville; known only from the type 
locality, where it is rare. The species is small, slender, and depressed. 
Pseudanophthalmus occidentalis Barr, new status 
Pseudanophthalmus tiresias occidentalis Barr 1959:18. Type locality, 
DePriest Branch Cave, Lewis Co., TN. 
Known only from the type locality cave and nearby Cave Branch 
Cave, Hickman County, Tennessee, this small, slender, depressed species 
is rare in both caves. It is potentially sympatric with P. hesperus Barr 
(engelhardti group), which occurs in the Blowing Caves, Perry County, 
Tennessee, but the two species have not yet been shown to coexist. 
Pseudanophthalmus acherontis Barr, new status 
Pseudanophthalmus tiresias acherontis Barr 1959:20. Type locality, Echo 
Cave, Rutherford Co., TN. 
Known only from the type locality cave, apparently a branch of the 
extensive Snail Shell Cave system (in the main trunk of which it has not 
yet been collected), this small, slender, depressed species is found in 
riparian microhabitats. All available specimens are unusually pale, 
rufotestaceous. 
Pseudanophthalmus tullahoma Barr, new status 
Pseudanophthalmus tiresias tullahoma Barr 1959:20. Type locality, 
Carroll Cave, Coffee Co., TN. 
The species is known only from Carroll and Riley Creek caves, Cof- 
fee County, Tennessee, both of which have been flooded by the Ten- 
nessee Valley Authority’s Normandy Dam on Duck River. In Carroll 
Cave this small, slender, depressed species occurred on rotting wood in a 
wet area, and in Riley Creek Cave it occurred in a muddy, periodically 
flooded area on rotting wood in which large numbers of Onychiurus 
collembolans were found.
