Fig. 12 
Pseudanophthalmus tenesensis Valentine 1937:98 (emendation). 
Length 3. 7-4. 2, mean 3.9 ± SD 0.2 mm (N = 12). Slender and 
depressed, somewhat parallel, pubescent. Head rounded. Pronotum wid- 
est in apical seventh, apex one-eighth wider than base, sides convergent 
and shallowly sinuate before somewhat obtuse, sharp, and slightly 
reflexed hind angles; base with prominent secondary angles; disc subgla- 
brous except 2-3 long setae each side. Elytra with humeri prominent, 
prehumeral borders perpendicular to midline, striae shallow, intervals 
nearly flat, apical groove short, joining 3rd stria behind level of 7th 
umbilicate puncture; pubescence of disc dense and not in rows. Aedeagus 
0.61-0.65, mean 0.63 mm, moderately arcuate, apex with small button. 
Pseudanophthalmus tennesseensis occupies caves in a long strike band 
of the Knox group which lies south of the Copper Creek fault in Knox 
and Roane counties, Tennessee. It is known from four caves: Grand 
Caverns (type locality, also known as Atomic Caverns), George Light 
Cave (1.7 km S Solway), and Rock Hill Cave (3.3 km S Heiskell), all in 
Knox County; and Eblen Cave (1.7 km SE Bradbury), Roane County. 
The known geographic range is approximately 40 km long. In all the 
caves P. tennesseensis was collected from under rocks on damp silt, not 
beside streams. Total length measurements given by Barr (1965:66) were 
0. 1-0.2 mm too small; the aedeagal lengths I previously reported are 
incorrect because of a typographical error.
