with small secondary angles on base. Elytra with one or both posterior 

 discal setae absent in about half of specimens examined (+0+). Aedea- 

 gus 0.71-0.80, mean 0.75 ± .04 mm long (N = 18). 



Type series.— Holotype male (American Museum of Natural His- 

 tory) and 18 paratypes, Bland Cave, 1.8 km NW Spurrier on N side 

 Akers Valley, Hardin Co., Kentucky (Millerstown 7%' Quadrangle), 28 

 December 1962, T. C. Barr, R. A. Kuehne. Measurements of holotype 

 (mm): total length 5.52, head 0.93 long X 0.74 wide, pronotum 0.99 long 

 X 1.09 wide, elytra 3.10 long X 2.02 wide, antenna 3.97 long. 



Distribution.— Limited to northwestern Hart County, Kentucky, 

 north of the Hart County Ridge, an extrinsic barrier (Barr 1979b), and 

 southwestern Hardin County (to Star Mills). 



Pseudanophthalmus globiceps , new species 

 Fig. 4 



Etymology. — Latin globus, "round," + -ceps, "head." 



Diagnosis.— Resembles pilosus in very convex, vaulted elytra with 

 dense discal pubescence, but head more rounded and pronotum propor- 

 tionately wider, base more nearly rectilinear than in other species close 

 to menetriesi, barely emarginate behind hind angles; aedeagus with 

 median lobe more strongly arcuate than other species of the menetriesi 

 series. 



Description.— Length 4.8-5.8, mean 5.3 ± 0.3 mm (N = 10). Head 

 and pronotum as described above. Elytra broad and quite convex but a 

 little less so than in pilosus; 6-7 finely impressed and strongly punctulate 

 striae, sutural stria deepest, intervals flat or nearly so, discal chaetotaxy 

 normal (+++); subhumeral margin slightly sinuate, greatest width behind 

 middle. Aedeagus of a paratype 0.73 mm, about as in pilosus but a little 

 narrower and more strongly arcuate, apex not briefly reflexed. 



Type series. — Holotype male (American Museum of Natural His- 

 tory) and 3 paratypes, Barnes Smith Cave, 5.7 km N Hinesdale, Hart 

 Co., Kentucky (Canmer l l / 2 ' Quadrangle), 30 December 1956, T. C. 

 Barr; 6 additional paratypes, same cave, 30 August 1963, T. C. Barr, J. 

 R. Holsinger; 2 July 1980, T. C. Barr, Jr., T. C. Barr, III. Measure- 

 ments of holotype (mm): total length 5.84, head 1.05 long X 0.98 wide, 

 pronotum 1.13 long X 1.23 wide, elytra 3.39 long X 2.26 wide, antenna 

 3.63 long. 



Distribution. — Known only from the type locality, a cave at the 

 south base of the Hart County Ridge, where P. globiceps coexists with 

 Neaphaenops tellkampji from the Mammoth Cave region and P. orien- 

 talis Krekeler, from the Greensburg area. There are few other caves in 

 the vicinity; an interaction with P. menetriesi is perhaps feasible, 

 although no suitable intervening caves have been sampled. The unusu- 

 ally convex elytra suggest common ancestry with P. pilosus, however, 

 not menetriesi.
