rows per interval; elytral microsculpture transverse-obsolescent, forming 
meshes. Head rounded, as long as wide; labrum singly emarginate; last 
segment of maxillary palp about 0.2 longer than penultimate segment; 
antenna rather short, 0.6 body length. Pronotum transverse-cordiform, 
0.8 as long as wide, width at base and apex subequal and 0.75 greatest 
width, which occurs in apical fourth behind anterior marginal setae; 
anterior angles prominent, sides shallowly sinuate, subparallel or conver- 
gent in basal fifth, hind angles large and sharp, right or slightly obtuse; 
secondary angles of base prominent but rounded. Elytra elongate-oval, 
1.8 times longer than wide, subconvex; prehumeral borders a little 
oblique, humeri prominent but slightly rounded, apexes bluntly rounded; 
short scutellar stria present, longitudinal striae deep, inner 3-4 complete 
with clear traces of 5,6,7, and 8, intervals convex, apical groove elongate, 
bisinuate, running to 3rd stria without crosier at level of 7th umbilicate 
puncture. Aedeagus of paratype 0.55 mm long, moderately arcuate, apex 
slender and produced, slightly falciform; parameres with 4-5 apical setae. 
Type series. — Holotype male (American Museum of Natural His- 
tory), 1 male and 2 female paratypes. Old Quarry Cave, 1.8 km SSE 
Ashcamp, Pike Co., Kentucky (Hellier IVi Quadrangle, 37^15'09" X 
82°25'29''), 2 August 1979, T. C. Barr, 
Measurements (mm). — Holotype, total length 3.92, head 0.72 long X 
0.70 wide, pronotum 0.69 long X 0.84 wide, elytra 2.23 long X 1.22 wide, 
antenna 2.42. 
Discussion. — This species, near the northeast end of Pine Mountain, 
is immediately differentiated by the unusually deep elytral striation and 
reduced pubescence. Old Quarry Cave is situated 100 m east of an old, 
abandoned limestone quarry at an elevation of 620 m. The beetles were 
taken from under rocks at the back of the entrance room and in the lower 
of two subparallel crawlways, all within 20-60 m of the entrance. Abun- 
dant cave rat debris was present. 
Pseudanophthalmus hypolithos and the next three species are re- 
stricted to caves in Pine Mountain, a huge fault block 125 km long, 
extending from Elk Gap, Campbell County, Tennessee, to Breaks Inter- 
state Park near Elkhorn City, Kentucky. The Newman limestone (Missis- 
sippian) crops out on the northwest face of Pine Mountain, dipping to 
the southeast at about 25-35°. Caves of Pine Mountain are of the Appala- 
chian pattern, with major passages along the strike and passages connect- 
ing different levels along the dip.
