Head about 1.15 times longer than wide, last segment of maxillary palp 
one-third longer than penultimate segment. Pronotum almost as long as 
wide, greatest width slightly behind anterior marginal setae, apex and 
base widths subequal, sides shallowly sinuate in basal fourth, hind angles 
acute, secondary angles of base prominent, disc with 2 long setae each 
side. Elytra nearly 1.8 times longer than wide, subparallel, depressed, 
humeri prominent even though prehumeral borders a little oblique, apex 
rounded; disc densely pubescent, inner 4 striae feebly impressed, traces of 
5th and 7th striae discernible, apical groove elongate, bisinuate, subparal- 
lel to suture. Aedeagus 0.47-0.48 mm long, evenly arcuate, closely similar 
to that of P. hirsutus, with simple apex. 
Compared with P. hirsutus, the pronotum of P. digitus is longer with 
acute (rather than obtuse) hind angles, and the elytral apexes are con- 
spicuously more rounded. Neither Valentine (1932) nor Jeannel (1949) 
was able to examine a male of this species, but they correctly surmised 
that it is closely related to P. hirsutus. Examination of the aedeagus in 
freshly collected material confirms this supposition. The species coexists 
in caves of Lookout Valley, Hamilton County, Tennessee, and Dade 
County, Georgia, with P.fulleri {engelhardti group). The type locality is 
Tennessee Caverns, Hamilton County. J. R. Holsinger and S. B. Peck 
collected a total of 9 specimens from Johnsons Crook and Byers caves, 
near Trenton, Dade County. 
Pseudanophthalmus ventus, new species 
Fig. 24 
Etymology. — Latin ventus, “wind.” 
Diagnosis. — Resembles P. digitus in size, habitus, rounded apexes of 
elytra, and aedeagal form; differs in longer head, shorter and wider pro- 
notum with convergent (=nonsinuate) sides and right hind angles, and 
more convex elytra. 
Description. — Length 3. 8-4. 2, mean 4.0 ± SD 0.1 mm (N = 6). Head 
1.3 times longer than wide, labrum with low median lobe, last segment of 
maxillary palp one-third longer than penultimate segment; antenna 0.75 
body length. Pronotum about 0.9 as long as wide, widest in apical sixth, 
sides convergent, not sinuate or barely sinuate before hind angles, which 
are right or slightly more than right; apex and base widths subequal and 
0.75 maximum width, secondary basal angles subdued; disc with 2-3 long 
setae each side in addition to sparse, short pubescence. Elytra 1.8 times 
longer than wide, moderately convex, elongate-oval, prehumeral borders 
slightly oblique to midline, humeri nevertheless prominent, apex rounded, 
with slight subapical sinuation; longitudinal striae all discernible (outer 
striae obsolescent in one specimen only), at least at base, intervals feebly
