1&54] Wilson, Eis7ier, and Valentine — North American Paralirnulodes 155 
Alabama: Bryce Lake, Tuscaloosa, Tuscaloosa Co. [host 
N eivamyrmex carolinense (Emery)]; Hurricane Creek, 
near Peterson, Tuscaloosa Co. [host N. carolinense] ; 
King Cove, Bankhead National Forest, Lawrence Co. [host 
N. nigrescens (Cresson)]. The species has been tentative- 
ly determined as P. ivasmanni. Since syntypes of ivasman- 
ni are not available at present, we have relied on Bruch’s 
original description and detailed drawings. No difference 
could be found on this basis, and we feel confident in stat- 
ing that the two populations must be very close if not

Morphology. (See figures. Most of the specimens used in 
this study were cleared with 10% KOH and stained with 
Chlorazol Black E, acid fuchsin, or fast green. Because of 
the minute size of the material, most of the examination 
was made under oil immersion lens.) 
Size extremely small, total length approximately 0.6 mm 
Antenna 8-segmented. Antennal fossa deeply excavated 
but nevertheless capable of accommodating only the scape. 
The antenna is otherwise well protected, being able to 
move freely between the prosternum and the concave ven- 
tral surface of the remainder of the prothorax. The ter- 
minal four segments are flattened dorsoventrally. A pair 
of what seem to be sensory pegs, one dorsal and one ven-
