pubescence rather long, 2-3 rows per interval. Aedeagus 0.47-0.49 mm 
long, similar to that of P. digitus but middle portion of median lobe 
straighter; apex finely attenuate. 
Type series. — Holotype male (American Museum of Natural History) 
and one paratype female, Ellis (=Sequoyah) Cave (AL 333), 3.3 km SW 
Sulphur Springs in T4S/ RlOE/ S20, Dekalb Co., Alabama, 9 August 
1965, S. B. Peck. One paratype male, same cave and collector, 25 August 
1965. 
Measurements (mm). — Holotype, total length 4.24, head 0.82 long X 
0. 73 wide, pronotum 0.78 long X 0.84 wide, elytra 2.33 long X 1.35 wide, 
antenna 2.86, aedeagus 0.49. 
Discussion. — From P. sequoyah, which also occurs in Ellis Cave, P. 
assimilis is easily distinguished by smaller size, cordiform pronotum with 
2-4 discal setae each side, subdued anterior angles and sharper hind 
angles, and shorter and more clearly bisinuate apical groove; the aedea- 
gus is very different. A single female of this species was collected March 
1, 1970, in Kudzu Cave (AL 734, T4S/R10E/S4), Dekalb County, by W. 
W. Torode. The specimen agrees closely with the type series but was not 
made a paratype. Ellis Cave lies on the west side of the Wills anticline in 
Wills Valley; caves on the east side of the anticline are inhabited by P. 
alabamae {alabamae group). Presumably P. assimilis is more closely 
related to P. digitus than is P. ventus, judging from external characters, 
but the less arcuate aedeagus of P. assimilis is distinctive. 
hubrichti group (new group) 
Aedeagal apex not arrow-shaped in dorsal view, but briefly attenuate 
and finely truncate {hubrichti) or bluntly rounded (egberti) or bluntly 
rounded and deflexed (vicarius). Mostly small species, 3. 4-4. 4 mm, but P. 
paradoxus ranges between 4. 3-4. 9 mm. Pronotum subcordiform, disc 
without long setae; form depressed, moderately slender. Type species: P. 
hubrichti Valentine. 
Distribution. — Giles, Russell, Scott cos., VA; Hawkins Co., TN. 
Pseudanophthalmus hubrichti Valentine 
Valentine 1948:13. Barr 1965:47 (in part). 
Length 3. 8-4.0 mm. Form a little subparallel, depressed; head rounded, 
labrum singly emarginate; pronotum transverse-cordiform, hind angles 
obtuse, sides very shallowly sinuate before base, which is oblique behind 
angles and shallowly emarginate between; elytra 1.6 times longer than 
wide, prehumeral borders oblique and humeri rounded, striae shallow 
and punctulate, intervals flat. Apical groove elongate, bisinuate, running 
via crosier to 3rd stria in advance of 7th umbilicate puncture, 5th and 6th
