Description: General form is shown in Figures 1 and 2. Head 
subrectangular, sides sub-parallel, slightly convex; posterior corners 
rounded ; occipital border slightly concave. Scape slightly curved 
distally, exceeding occipital border by a distance about equal to its 
maximum diameter. Antennae 1 1 -segmented, with a 3-segmented 
club, the apical segment about 3 times as long as the preapical. Eyes 
strongly convex, maximum diameter (in all specimens) 0.13 mm; 
their anterior edges at a distance of 0.7 X their diameter from the 
lateral genal border. Outer borders of mandibles convex; masticatory 
border with 5 teeth, the 2 apical enlarged. Clypeus produced ante- 
riorly, forming a shelf over the mandibular bases and bulging out- 
wards; anterior border convex, with thick lateral sections anterior to 
each antennal sulcus; posterior portion extending broadly between 
the frontal carinae. 
Mesosomal profile as in Figure 2 ; lacking a promesonotal con- 
striction, humeral angles indistinctly rounded. Mesometanotal im- 
pression weakly developed on mesosomal dorsum as a very shallow 
concavity, lacking an incised sutural trace. Propodeal spines moderate- 
ly long, pointed, uncurved. Petiolar node from above, oval, distinctly 
wider than long. Postpetiole with convex anterior and posterior 
margins and convex sides. Dorsal width of first gastric segment 2.1 X 
postpetiole width. 
Head and mesosoma strongly reticulate-punctate and mat; petiole, 
postpetiole and gaster moderately reticulate and shining. 
Yellow pilosity on clypeus, mandibles and posterior end of gaster. 
Yellowish adpressed pubescence dense on antennae, moderate on head, 
petiolar node, postpetiolar dorsum, and gaster. 
Entire body yellow to dark yellow.
