at apex and base subequal and 0.75 maximum width; sides rather 
abruptly sinuate at basal 0.4, then convergent to large, obtuse hind angles, 
base oblique behind angles, secondary angles small and inconspicuous; 
disc rather convex, with 3 long setae each side and scattered pubescence. 
Elytra 1.75 times longer than wide, widest behind the middle, prehumeral 
borders oblique to midline, humeri somewhat rounded, antapical sinua- 
tion shallow; disc convex, deplanate near scutellum, rather densely 
pubescent; striae regular and shallow but deeper than usual for jonesi 
group, intervals subconvex, apical groove elongate and subparallel to 
suture, running into 3rd stria. Male unknown. 
Type series. — Unique holotype female (American Museum of Natural 
History), Sawmill Hollow Cave, 2.0 km NNW Nolansburg and 600 m 
ESE Pine Mountain Settlement School on the northwest slope of Pine 
Mountain, elevation 700 m (Nolansburg IVi Quadrangle, 36°56'50" x 
83^10'31"), 23 August 1979, T. C. Barr, Jr., and T. C. Barr, HI. 
Measurements (mm). — Holotype, total length 4.65, head 1.01 long X 
0.80 wide, pronotum 0.83 long X 0.92 wide, elytra 2.63 long X 1.50 wide, 
antenna 3.21. 
Discussion. — Even though no male is available, the species is readily 
differentiated on external characters alone. It is evidently related to P. 
jonesi and P. scutilus, differing in the pronotal and elytral strial charac- 
ters cited in the diagnosis. Sawmill Hollow Cave is a small cave (length 
about 300 to 400 m) consisting of muddy crawlways on two or three 
levels, with a small stream and a pool in the lowest level; the cave is in 
Newman limestone dipping southeast at about 32^. The unique holotype 
was collected at the lower end of a section of the cave called “The Emper- 
or’s Palace”, a small stream channel intersected by a 10-m dome. 
Pseudanophthalmus seclusus, new species 
Figs. 42, 50 
Etymology. — Latin seclusus, “remote, separated.” 
Diagnosis. — Distinguished from other species of the group by the 
following combination of characters: labrum with prominent median 
lobe, elytra subconvex with subparallel sides and broadly rounded 
apexes, head nearly 1.3 times longer than wide, elytral striae shallowly 
impressed and inner intervals subconvex, aedeagus with apex briefly 
reflexed and obliquely truncate. 
Description. — Length 4.2-5. 0, mean 4.6 ± SD 0.2 mm (N = 40). Pale 
rufotestaceous, form rather elongate and subconvex, pubescent. Head 
1.25-1.28 times longer than wide, labrum with prominent median lobe in 
anterior margin (doubly emarginate), antenna 0.6 times body length. 
Pronotum 0.85 times as long as wide, greatest width in apical fourth
