Pseudanophthalmus paulus, new species 
Fig. 18 
Etymology. — paulus, “little, small.” 
Diagnosis. — Related to P. hirsutus and P. digitus', pronotum only 0.7 
as long as wide, hind angles right, greatest width in apical third behind 
anterior marginal setae; elytral apexes individually rounded, only 2 com- 
plete longitudinal striae, inner 3 intervals subconvex, medial umbilicate 
punctures widely spaced: distance between 4th and 5th punctures about 
1.2 times distance between 5th and 6th punctures. 
Description. — Length 3. 7-3. 8 mm. Head 0.1 longer than wide; ante- 
rior margin of labrum with low median lobe, 3rd segment of maxillary 
palp 0.75 as long as 4th segment; antenna 0.6 total length. Pronotum 0.7 
as long as wide, more transverse than in other species of hirsutus group, 
apex about 0.1 wider than base and 0.7 greatest width, which occurs in 
apical third behind anterior marginal seta, sides subparallel in basal fifth, 
hind angles right, secondary angles of base obsolescent; disc with usual 
sparse, short pubescence and 2 or 3 long setae each side, but these less 
conspicuous than in other species of the group. Elytra 1.8 times longer 
than wide, depressed, prehumeral borders nearly perpendicular but 
humeri not unusually prominent, apexes individually rounded, with 
slight subapical emargination; only inner 2 longitudinal striae complete, 
but inner 3 intervals subconvex, each with 2-4 rows of fine pubescence; 
apical recurrent groove elongate, bisinuate, slightly oblique, connected to 
3rd stria by crosier. Male unknown. 
Type series. — Holotype female (American Museum of Natural His- 
tory) and one female paratype, Nobletts Cave, 4.8 km W Sweetwater on 
the west side of Watson Ridge, Monroe Co., Tennessee, 4 January 1967, 
Russell M. Norton. 
Measurements (mm). — Holotype, total length 3.73, head 0.82 long X 
0.73 wide, pronotum 0.67 long X 0.99 wide, elytra 1.99 long X 1.13 wide, 
antenna 2. 19. 
Discussion. — The cave in which P. paulus occurs is 0.8 km south of 
Tennessee Highway 68 and only 0.5 km east of the McMinn County line 
(Niota IVi Quadrangle, 35°35'33" X 84°31'02"). It is a small, muddy 
Stream cave about 1 15 km northeast of the range of P. digitus and 215 km 
southwest of that of P. hirsutus.
