the surface here prevailingly smooth and shining. Color piceous, 
nearly black, with contrasting tan appendages. 
Worker, holotype: TL 5.2, HL 0.96, HW 0.86 (Cl 90), ML 0.48 
(MI 50), SL 0.73 (SI 85), EL 0. 14, WL 1 .60, hind femur L 0.80, hind 
tibia L 0.83 mm. 
Description mainly directed at details not fully covered in the 
diagnosis and figures. Antennal scape broadly curved in basal half, 
incrassate distad; apical width about 0.12 mm, or slightly less than 
maximum eye length. Funicular segment I about twice the length of 
II. Eye with distinct but fine ommatidia, numbering about 1 1 or 12 
units in the longest diagonal row, darkly pigmented. Median clypeal 
lobe about 0.05 mm long (CLL) and about 0.14 wide (CLW) at 
apex, about 0.15 mm wide at base where it meets frontal lobes; 
anterior border straight, free corners subrectangular. In examining 
the single, intact specimen, no upturned teeth could be seen at the 
apex of each labral lobe, but a dissection would be needed to make 
sure that they are really absent. Mandibular armament consists of 
an acute apical tooth and a small adjacent tooth, then after a gap 
another large, blunt tooth, another gap and a similar-sized but more 
acute median tooth, then halfway from this to the base, a low, 
rounded basal angle. Oblique groove (strix) near dorsal base of 
mandible distinct, continuing along lateral margin to near apex. 
MLO 0.77 mm. 
Trunk robust, dorsal outline in side view nearly straight, the 
mesonotum feebly sunken; metanotal groove slightly impressed, but 
distinct; propodeal dorsum very feebly convex, rounding obtusely 
into declivity, but sides of declivity forming blunt angles with pleu- 
ral faces of trunk. Propodeal spiracle small and round, situated at 
mid height. Petiolar node massive, subcuboidal, slightly wider 
behind than long; slightly higher than long if one ignores the small, 
hooklike anterior subpetiolar process; dorsal surface convex in both 
directions. 
First gastric (postpetiolar) segment higher and wider (by about 
4:3) than long. Succeeding (gastric II) segment about as wide as the 
first, and only slightly longer, but slightly thinner dorsoventrally. 
Sting long and slender, gently upcurved. 
Sculpture distinctive, consisting basically of a smooth, shining 
integument invaded by coarse, mostly umbilicate, piligerous foveo- 
lae. The foveolae are densest and smallest (0.02-0.03 mm diameter)
