front margin slightly concave; hind margin slightly concave; disc 
finely punctulate ; finely striolate. 
Elytra fused; at base slightly wider than base of pronotum; widest 
near middle; anterior margins subparallel; surface punctate, punc- 
tures indicating striae; finely striolate; sides and apex smooth. Pro- 
tibia straight on outer margin ; sinuous on inner margin ; widening 
to apex in apical 2/3; setose on apical half of inner margin; spinose 
along outer margin ; two large spines at outer apical angle ; two 
shorter spines on inner margin at origin of tarsus; comb of short 
spines below origin of tarsus. Mesotibia straight and spinose along 
outer margin; curved and setose along inner margin; expanding to 
apex in apical 2/3; outer apical angle sharp, possessing two spines; 
one large spine along ventral edge of apical margin. Metatibia 
stout, gradually widening to apex ; outer and inner margin smooth ; 
curved slightly so that apex is deflected outward ; straight in lateral 
view; one large spine at outer apical angle and one in middle of 
apical margin; dense patch of setae along upper and inner margin 
of apex. Fifth abdominal segment evenly rounded. 
Male first three protarsomeres widely expanded and supplied with 
a dense mat of hairs; first three mesotarsomeres less expanded and 
hairy. Aedeagus in lateral view bent near base, basal anterior pro- 
jection deflected downward, body of aedeagus slightly sinuous and 
tapering, ventral surface projecting posteriorly to form shelf under 
genital orifice, dorsal surface curving downward slightly; in ventral 
view robust, sides parallel, dorsal surface tapering only at apex and 
smooth in outline, ventral surface with apical tooth-like projection; 
parameres gradually tapering to point, terminating close to aedeagal 
apex, basal pieces thin (figs. 8, 9). 
Female tarsomeres not expanded. 
Variation. No noteworthy variation is evident in the seven known 
specimens. 
Etymology. I am pleased to name this species for Dr. Walter B. 
Jones, retired State Geologist of Alabama, in recognition of his as- 
sistance to me and to other students of Alabama cave fauna. 
Distribution. Known only from Morgan, Marshall and Jackson 
Counties in northeastern Alabama (map 1 ).
