Thomas C. Barr, Jr. 
less hyaline hemisheath, its apex a bluntly rounded knob, left piece a little 
shorter, broadly triangular, densely but minutely spiny, with apex twisted 
90° to right and thus appearing as narrow, nipplelike or broadly 
spatulate, depending on orientation; parameres rather slender, with 4 
apical setae. 
Type series . — Holotype male (American Museum of Natural 
History) and one female paratype, Carter Cave, 5.5 km ssw of Flynns 
Lick, Jackson Co., Tennessee, 23 October 1960, T. C. Barr. Two ad- 
ditional paratypes from same cave, 9 June 1955 and 20 July 1957, T. C. 
Barr. Three paratypes from Hailes Cave, 0.5 km n of Flynns Licks, 6 
May 1959, T. C. Barr, and 19 October 1948, J. M. Valentine and W. B. 
Jones. (See Barr 1961 for detailed locations and descriptions of these and 
other caves mentioned in this paper.) 
Measurements (in mm).— Holotype male, total length 4.60, head 
0.80 long X 0.80 wide, pronotum 0.90 long X 1.10 wide, elytra 2.66 long 
X 1.72 wide, antenna 3.06, aedeagus 0.86 long. 
Distribution. — The material seen of this species includes the type 
series of 7 specimens and one specimen (not a paratype) from Cherry 
Cave, northeast Jackson County, Tennessee. The three caves from which 
the species is known are located at the northeast edge of the Central 
Basin in the upper Cumberland River drainage; all of the caves are on the 
south (left) side of Cumberland River. 
Discussion . — In Carter Cave the species occurs sympatrically and 
syntopically with a more abundant species, P. productus, of the 
cumberlandus group, under rocks and on silt banks by the cave stream. 
Females and undissected males can be distinguished by the more robust 
and more depressed form and by the deeper elytral striation. The 
aedeagus of simplex has a shorter and less produced apex than that of 
productus, and the transfer apparatus consists of two prominent sclerites 
instead of the small, single, very slender sclerite characteristic of the 
cumberlandus group.

Etymology. — Patronymic honoring Mrs. Otia Fowler, owner of the 
type locality cave. 
Diagnosis.— Differs from simplex in shallow, irregularly punctate 
elytral striae, glabrous and non-pruinose elytral disc, microsculpture with
