Appalachian Pseudanophthalmus

to strongly bisinuate, running directly into 3rd stria, no crosier; all fixed 
setae hypertrophied, unusually long. Aedeagus of holotype 0.61 mm 
long, moderately arcuate, apex finely and simply attenuate. 
Type series. — Holotype male (American Museum of Natural History) 
and 3 female paratypes. Little Kennedy Cave, Wise Co., Virginia (Appa- 
lachia IVi' Quadrangle, 36°53'24' x 82''45'01'), 26 November 1970, J. R. 
Holsinger, Roger Baroody, and R. M. Norton. 
Measurements (mm). — Holotype, total length 4.88, head 0.88 long X 
0.78 wide, pronotum 0.84 long X 0.90 wide, elytra 2.49 long X 1.57 wide, 
antenna 3.00, aedeagus 0.61. 
Discussion. — Together with P. longiceps and P. thomasi this species 
forms a trio of rather large, unusually attenuate species with long append- 
ages. Little Kennedy Cave, near the edge of the Allegheny front in 
Newman limestone (Mississippian), was described by Holsinger (1975: 
402). The cave is about 40 km north of the type locality of P. thomasi (to 
which P. cordicollis is most closely similar) and 65 km northeast of the 
type locality of P. longiceps. 
hypolithos group (new group) 
Aedeagus with apex long and slender, not arrow-shaped in dorsal view, 
bluntly rounded or slightly falciform at tip. Size small (3. 7-4. 3 mm, most 
species means about 4 mm), form moderately slender and depressed; 
pronotum transverse-cordiform, sides shallowly sinuate before hind 
angles, disc without long setae. Type species: P. hypolithos, new species. 
Distribution. — Pike, Harlan, Bell, and Whitley cos., KY (Pine Moun- 
tain); Scott Co., VA. 
Discussion. — Four of the small species of this group occupy different 
caves in Pine Mountain, Kentucky, a large fault block in which the 
Newman (Mississippian) limestone is exposed on the northwest face. The 
fifth species {P. praetermissus) occurs in a cave in Hunter Valley, Scott 
County, Virginia, near the base of the Allegheny front but in the edge of 
the Appalachian valley.

Figs. 28, 34 
Etymology. — Greek hypo-, “under,” + lithos, “rock.” 
Diagnosis. — Distinguished from other members of the group by the 
rather deep and complete elytral striation, convex intervals, reduced 
pubescence, and falciform aedeagal apex. 
Description. — Length 3.9-4. 3, mean 4.0 mm (N = 4). Form elongate, 
rather slender, depressed; rufotestaceous, shining, head and pronotum 
subglabrous, elytra with short and sparse pubescence, limited to 1 or 2
