Appalachian Pseudanophthalmus 
49 
with very sparse and short pubescence. Elytra 0.67 times longer than 
wide, elongate-oval, prehumeral borders perpendicular to midline, humeri 
serrate and setose; all longitudinal striae impressed, intervals subconvex, 
with 1-4 rows of pubescence, apical recurrent groove bisinuate, conspicu- 
ously oblique to suture, connected to 3rd stria by crosier; microsculpture 
obsolete on center of disc. Aedeagus 0.57 mm long (holotype), strongly 
arcuate, apex with ventral cusp. 
Type series. — Unique holotype male (American Museum of Natural 
History), Grassy Creek Cave, 0.7 km S Washington, Rhea Co., Tennes- 
see, 3 July 1967, R. M. Norton. 
Measurements (mm)." — Holotype, total length 4.28, head 0.80 long X 
0.80 wide, pronotum 0.86 long X 0.95 wide, elytra 2.30 long X 1.38 wide, 
antenna 2.63 long, aedeagus 0.57. 
Discussion. — The type locality cave lies between the Allegheny front 
(Waldens Ridge) and the west (right) bank of Tennessee River; it is 
developed along a sinking section of Grassy Creek (Evensville IVi Quad- 
rangle, 35^3 T40" X 84°54"44"). Judging from overall habitus and aedea- 
gal morphology, P. nortoni is closer to P.fulleri, P. nickajackensis, and 
other “southern” species of the group than to the more geographically 
remote species along the Virginia-Tennessee border. 
Pseudanophthalmus fulleri Valentine 
Valentine 1932:272. Barr 1965:66. 
Length 4.0-4. 5 mm; head rounded, labrum singly emarginate; prono- 
tum transverse, almost subquadrate, with shallow lateral sinuation and 
large, obtuse hind angles; elytra with angular humeri, widest at middle, 
subconvex, striae very shallow, intervals flat to weakly convex, apical 
groove elongate, oblique, bisinuate; apex of aedeagus hatchet-shaped, 
with sharp ventral cusp, moderately arcuate. 
In a previous paper (Barr 1965) I reported a 20 km range extension for 
this species, from Tennessee Caverns, Hamilton County, Tennessee (type 
locality), to Howards Waterfall Cave, 3.5 km southwest of Trenton, 
Dade County, Georgia, predicting that future collecting in Dade County 
caves “will eventually yield more P.fulleri and perhaps even the less well 
known P. digitus. ...” In 1967 and subsequently, J. R. Holsinger, S. B. 
Peck, and their associates collected P. fulleri in the following Dade 
County caves, all of them in Lookout Valley on the west side of Lookout 
Mountain: Byers Cave, 2.5 km SW Rising Fawn; Johnsons Crook Cave, 
7.5 km NE Rising Fawn; Howards Waterfall Cave (additional speci- 
mens); Morrison Cave, 3.5 km E Trenton; Sittons Cave, 3.5 km SE 
Trenton; Deerhead Cove Cave, near Trenton (T. lies and A. Dobson, 
•eg).
