Appalachian Pseudanophthalmus

less than right angle to median lobe, which is swollen near base of inter- 
nal sac; apex briefly attenuate, deflexed, slightly knobbed, rounded at tip; 
parameres rather broad, with 3 or 4 long apical setae. 
Type series. — Holotype male (American Museum of Natural His- 
tory), Sensabaugh Saltpeter Cave, about 8 km W Kingsport, Hawkins 
Co., Tennessee (Church Hill IVi' Quadrangle, 36^33'57" X 82''38'05"), 
May 1968, Sam Taylor and Dick Powers, leg. One paratype female, same 
cave, 16 June 1963, L. G. Conrad. Six paratypes, same cave, 17 July 
1979, T C. Barr, Jr., T. C. Barr, III, and J. R. Holsinger. 
Measurements (mm). — Holotype, total length 4.92, head 0.94 long X 
O. 88 wide, pronotum 0.85 long X 1.03 wide, elytra 2.73 long X 1.58 wide, 
antenna 3.21, aedeagus 0.95. 
Discussion. — The form of the aedeagus is strikingly similar to that of 
P. vicarius. At present P. paradoxus is the only known Tennessee 
Pseudanophthalmus species in the Holston Valley and the only known 
species south of Clinch Mountain. The type locality cave opens near the 
top of a wooded ridge in a subdivision of Kingsport; from the mouth a 
steep, muddy slope drops about 40 m to a small stream. The specimens 
collected in July 1979 were taken from under rocks and rotten wood near 
a ceiling drip, and no specimens were encountered along the stream. The 
microhabitat is thus similar to that of P. longiceps (jonesi group), another 
species of rather large size which inhabits caves high on a ridge. Sensa- 
baugh Saltpeter Cave is also known as Moffitt Saltpeter Cave or simply 
“Saltpeter Cave;” another cave in the vicinity, described as Click Creek 
Cave by Barr (1961), is sometimes locally called “Sensabaugh Cave” 
because it is near the Sensabaugh (railroad)Tunnel. 
jonesi group (new group) 
Aedeagus with apex produced, long and slender, not arrow-shaped in 
dorsal view, in lateral view tapering to a point (P. cordicollis), with a 
terminal button {P. seclusus), or simply bluntly rounded. Most species 
large to medium-large (4. 2-6. 2 mm), although one species {P. pallidus) is 
3. 9-4. 3 mm. Form slender to very slender, convex, appendages elongate; 
pronotum elongate-cordiform with sides shallowly sinuate before small 
hind angles, disc with 1-4 long setae each side. Type species: P. jonesi 
Valentine. 
Distribution. — Lee, Scott, and Wise cos., VA; Harlan Co., KY; 
Campbell, Claiborne, Cumberland, and Hancock cos., TN.
