on anterior and sides of head, where most are contiguous and yield a 
reticulate-foveolate surface that is subopaque in most lights. This 
kind of sculpture, a bit more loosely distributed, covers the upper 
sides and dorsum of trunk and petiole, except for median posterior 
part of vertex, midline of trunk, and dorsal midline of petiole, which 
have wide spaces free of most foveolae, and are smooth, shining. 
Sides of trunk below largely smooth, with sparse foveolae, and 
posteriorly, low down, with a few fine, longitudinal costulae. Sides 
of petiolar node foveolate-striate. Caster with spaced foveolae, 
becoming smaller (0.02 mm) and sparser caudad, interspaces 
smooth and shining, but a double band of foveolae along apical 
margin of second gastric tergum. Mandibles and legs with sparse 
punctures, generally otherwise smooth and shining; scapes and 
middle tibiae, and all tarsi, more densely punctulate, but still 
shining. 
Hairs numerous, fine, tapered, suberect to decumbent, mostly 
0.04 to 0.25 mm long; those on head and appendages mostly short, 
while those on clypeal lobe, trunk, petiole, and especially gastric 
apex are longer. 
The species is named for Dr. Ruth Lippitt Willey. 
Holotype (MCZ) a unique worker specimen from Bubia, about 13 
km NW of Lae, Papua New Guinea, about 20 m above sea level, in 
high-graded rainforest, 26 March 1955, by E.O. Wilson (MCZ). The 
worker was foraging under the bark of a large Zoraptera-stage (rot- 
ting) log. 
This species is distinct from all congeners, but difficult to place to 
a group. Probably it comes closest to the tenuis group than any 
other so far described, but the longish head, bulging eyes, short 
scapes and coarsely foveolate sculpture will distinguish it from all 
tenuis-gxoup species.

(Figs. 2, 3, 25) 
Diagnosis, worker and queen: Head distinctly longer than broad; 
median clypeal process obsolete; labrum without median tubercle. 
Mandibles much broadened, each with the two major teeth before 
the apex exaggerated into triangular lobes; blades of mandibles 
sharply curved ventrad and rotated so that their blades lie nearly 
parallel to the sagittal plane of the head at full closure. Antennal
