Appalachian Pseudanophthalmus 
85 
Diagnosis. — Differs from other species of the group in the attenuate 
elytral apexes, deflexed aedeagal apex, and somewhat more robust form. 
Description. — Length 3.9 mm (in 2 specimens of the type series). 
Form as in P. hypolithos but more robust; pubescence moderate on 
genae and pronotum disc, dense on elytra, longer than in P. hypolithos, 
2-3 rows per interval. Head rounded; labrum singly emarginate; last seg- 
ment of maxillary palp 0.3 longer than penultimate segment; antenna 0.6 
body length. Pronotum 0.8 as long as wide, apex and base widths sub- 
equal and about 0.7 greatest width, which occurs in apical fourth; sides 
conspicuously sinuate and subparallel in basal fifth, anterior angles 
prominent, hind angles large, sharp, slightly obtuse, secondary angles of 
base low, broad, rounded. Elytra elongate-oval, prehumeral borders a 
little oblique, humeri prominent though somewhat rounded, apexes 
attenuate; no separate scutellar stria, longitudinal striae finely impressed, 
intervals weakly subconvex, inner 4 striae present, outer striae obsolete; 
apical groove elongate and bisinuate, running to 3rd stria via short cro- 
sier. Aedeagus of holotype 0.55 mm long, apex produced, slender, and 
conspicuously deflexed, finely and bluntly rounded at tip. 
Type series. — Holotype male (American Museum of Natural History) 
and one female paratype. Sawmill Hollow Cave, 2 km NNW Nolansburg 
and 600 m ESE Pine Mountain Settlement School on the northwest side 
of Pine Mountain, Harlan Co., Kentucky (Nolansburg IVi Quadrangle, 
36°56'50" X 83°I0'31"), 23 August 1979, T. C. Barr, Jr., and T. C. Barr, 
III. 
Measurements (mm). — Holotype, total length 3.95, head 0.69 long X 
0.70 wide, pronotum 0.73 long X 0.87 wide, elytra 2.33 long X 1.29 wide, 
antenna 2.25, aedeagus 0.55. 
Discussion. — This species coexists with P. rogersae (jonesi group) in 
Sawmill Hollow Cave, the only known case of sympatry in Pine Moun- 
tain caves. While P. scholasticus occurs in the upper level near the 
entrance, P. rogersae was collected in the lower level beside a small 
stream. A similar microhabitat segregation was observed in the same cave 
between a troglophilic (upper level) and a troglobitic species of Pseudo- 
tremia millipeds. The elytral apexes in P. scholasticus are more attenuate 
than in the other species of the group, and the deflexed aedeagal apex is 
also diagnostic.

Etymology. — Latin calcareus, “pertaining to limestone.” 
Diagnosis. — Distinguished from other group species by the elongate 
head, narrower pronotum, and wider elytra with rounded apexes and
