Batriasymmodes (s. str.) parki, new species 
Fig. 1 
Etymology. — It gives me great pleasure to name this species in 
honor of my late colleague and friend, Professor Orlando Park. 
Diagnosis . — A species of Batriasymmodes, s. str., resembling quis- 
namus Park in antennal characters but with the general aedeagal pat- 
tern of monstrosus (LeC.) and greeveri Park; projections of ventral plate 
and movable process elongate as in greeveri, but apex of movable pro- 
cess very deeply bifid and bent at right angle to left. 
Description. — Total length 2.96 mm (holotype). Head 0.66 mm long 
x 0.54 mm wide, pronotum 0.60 mm long x 0.56 mm wide, elytra 0.86 
mm long x 0.96 mm wide, abdomen 0.98 mm long x 0.82 mm wide. 
Head with pair of nude vertexal foveae, median vertexal carina fine, 
oblique vertexal carinae replaced by low, noncarinate ridges; eye ovoid, 
rather strongly convex, slightly emarginate on posteroventral side, with 
about 40 facets. Antenna with club formed by distal three segments; 
VIII with large, triangular, laminoid spine directed distally from ventral 
side; IX with very deep, transverse and slightly oblique ventral groove, 
distal margin of which is fimbriate and overhangs the cavity as in quis- 
namus, but much more strongly developed; X slightly knobbed beneath 
and narrowed apically; VII and XI normal, without special modifica- 
tions. Pronotum about as in suteri Park, with deep median fovea 
flanked by an elongate, laminoid spine either side; lateral to each spine 
a fovea which is continued apically as a shallow sulcus. Each elytron 
with three nude antebasal foveae and flank with one nude subhumeral 
fovea, as in suteri and greeveri. Metathoracic wings present. Abdomen 
with five simple tergites and five sternites, second sternite with trans- 
verse tumulus each side, fifth sternite with large, shallow concavity. 
Legs with protibia bearing conspicuous arcuation on distal half of dor- 
somesial face, all femora simple; each metatrochanter with short, re- 
curved spine. Aedeagus with movable process and medial process of 
ventral plate elongate, as in greeveri; apex of movable process deeply 
bifid and bent laterad at right angle. Female unknown. 
Holotype . — Male, a unique, Neely Farm Cave, just southeast of 
Athens, Mercer Co., West Virginia, 31 May 1969, J. R. Holsinger and 
Roger Baroody. Type deposited in Field Museum of Natural History, 
Chicago. 
Discussion . — This is the 15th species to be assigned to Batriasym- 
modes and the fifth cavernicole in the genus. It is most closely allied to 
quisnamus and greeveri; in Park’s (1965:186) key to species it will run 
to greeveri, a species from a cave in Sullivan County, Tennessee, close
