apex produced and cuspate ventrally, cusp sharply recurved. 
Type series. — Holotype male (American Museum of Natural His- 
tory), and 87 paratypes, Nickajack Cave, 1.0 km S Shellmound Station 
near the mouth of Nickajack Cove, Marion Co., Tennessee, 2 July 1967, 
S. B. Peck and A. Fiske; 10 paratypes, same cave, 29 July 1967, S. B. 
Peck, A. Fiske, J. E. Cooper; 8 paratypes, same cave, 1 1 November 1967, 
J. E. Cooper, J. R. Holsinger, M. Richmond. 
Measurements (mm). — Holotype, total length 4.72, head 0.88 long X 
0.84 wide, pronotum 0.88 long X 1.06 wide, elytra 2.65 long X 1.59 wide, 
antenna 2.08, aedeagus 0.65. 
Discussion. — Pseudanophthalmus nickajackensis is readily diagnosed 
by the recurved cusp on the ventral side of the aedeagal apex. The species 
is known only from the type locality, a large stream cavern which was 
unfortunately flooded late in 1967 by the waters of Nickajack Reservoir 
and is no longer accessible. The cave was described by Barr (1961:305), 
and a map of the cave was published by Matthews (1971: 133). Nickajack 
Cave is on the south (left) side of the Tennessee River; most of the cave 
lies in Marion County, Tennessee, but a small part extends under Jack- 
son County, Alabama.

Fig. 10 
Etymology. — Place name, noun in apposition. 
Diagnosis. — Resembling P. fulleri, but differing in slightly longer 
head, pronotum hind angles right, elytral humeri less angular and inter- 
vals convex, aedeagus more arcuate with shorter copulatory pieces. 
Description. — Length 4. 5-5.0, mean 4.7 ± SD 0.1 (N = 10). Moder- 
ately robust, subconvex, pubescent, rufotestaceous; microsculpture of 
head rather strongly isodiametric, satiny-smooth isodiametric at center 
of pronotum apex and base but very finely transverse elsewhere on disc, 
very fine and transverse without forming meshes on elytral disc. Head 
one-eighth longer than wide, labrum singly emarginate, maxillary palp 
with last segment a little longer than penultimate segment; antenna two- 
thirds body length. Pronotum transverse-subquadrate, a little less than 
0.9 as long as wide, width at apex and base subequal and about 0.75 
greatest width, which occurs in apical fifth; anterior angles very promi- 
nent, produced; sides subparallel in basal fourth, hind angles large, about 
right, somewhat reflexed, and blunt; base with conspicuous secondary 
angles; disc glabrous. Elytra almost subparallel, 1.6 times longer than 
wide, prehumeral borders not quite perpendicular to midline, humeri 
prominent though rounded, disc subconvex; very short scutellar stria 
present, inner 3 longitudinal striae well impressed, outer striae progres- 
sively feebler and irregular, intervals convex with 3-4 rows of pubescence;
