6(5). Aedeagus with apex strongly deflexed, falciform, slightly knobbed (Fig. 
39); apical groove of elytron subparallel to suture; northwest GA, 
northeast AL alabamae group 
Aedeagus with apex not knobbed, not or but slightly reflexed at tip 
(Figs. 34-38); Pine Mountain, KY, and Scott Co. (Hunter Valley), VA 
hypolithos group (new group) 
Occasional specimens of P. alabamae and P. georgiae {alabamae 
group) have 1-3 long setae on the pronotum, so specimens from 
northwest Georgia or northeast Alabama should be checked against Fig. 
39. 
engelhardti group 
Aedeagus more or less constricted before apex, which is arrow-shaped 
in dorsal view. Length 3. 6-5.4 mm, mean lengths about 4.0-4. 5 mm in a 
majority of species. In many species the aedeagal apex bears a sharp, 
ventral cusp when examined in lateral view (Figs. 5, 7-1 1); in others the 
apex is more or less attenuate and produced, with or without a terminal 
knob (Fig. 6). Form subdepressed, pronotum more or less cordiform and 
moderately to strongly transverse, pronotal disc without long setae in 
addition to normal pubescence (except in west-central Tennessee). Type 
species: P. engelhardti (Barber). 
Distribution. — Lee Co., VA; Anderson, Campbell, Claiborne, 
Decatur, Hamilton, Hancock, Marion, Perry, Rhea, Union cos., TN; 
Blount, Colbert, Dekalb, Jackson, Lauderdale, Lawrence, Madison, 
Marshall, Morgan cos., AL; Dade, Walker cos., GA. The group is appar- 
ently bicentric in distribution with several species along the Virginia- 
Tennessee border and the remainder in the lower Tennessee River valley, 
from Chattanooga westward. 
Pseudanophthalmus engelhardti (Barber) 
Anophthalmus engelhardti Barber 1928:195. 
Length 3.6-4. 1, mean 3.8 mm. Head rounded; pronotum subglabrous, 
5/6 as long as wide, cordiform, greatest width in apical fifth just behind 
anterior marginal setae, sides subparallel in basal fifth, hind angles large, 
about right, sharp; elytra narrow, 1.7 times longer than wide, humeri not 
sharply angular, stria 1-3 well impressed but intervals essentially flat, 
apical groove elongate and bisinuate, joining apex of 3rd stria via crosier 
at level of 7th umbilicate puncture, usually 2 irregular rows of short but 
moderately dense pubescence each interval; aedeagus rather strongly 
arcuate, apex rather narrow, sharp ventral cusp slightly reflexed, para- 
meres slender with 3 apical setae. 
This species is known only from English Cave, Claiborne County, 
Tennessee (see Barr 1961 for location, description, and map), where it is
