posterior border, and broadly rounded posterior corners. Worker 
eyes reduced to dots. Frontal lobes and median clypeal lobe large; 
clypeal lobe squarely truncate. Antennae very robust; scapes over- 
reaching posterior border of head; funiculus dominated by a long, 
thick, 4-merous apical club. Trunk compact, weakly convex, sepa- 
rated into two subequal parts by a distinct but not sunken metanotal 
groove. Petiolar node short and high, summit posterior and acutely 
rounded, posterior face vertical and feebly concave. Gaster con- 
stricted behind first segment. Integument smooth and shining, with 
separated minute punctures. Color dark yellowish brown. 
Worker, holotype: TL 4.1, HL 0.79, HW 0.70 (Cl 89), ML 0.30 
(MI 38), MLO 0.54, SL 0.66 (SI 94), EL 0.04, WL 1.27, hind femur 
L 0.68, hind tibia L 0.61 mm. 
Worker paratypes (15 from type nest series) range downward 
from size of holotype to smallest individual, TL 3.9, HL 0.75, HW 
0.68 (Cl 91), ML 0.29 (MI 39), MLO 0.49, SL 0.62 (SI 91), EL 0.04, 
WL 1.20 mm. 
Head a little longer than broad, with parallel gently convex sides, 
straight posterior border, and rounded posterior corners. Frontal 
lobes broad, median clypeal lobe thick and wide (CLL 0.07, CLW 
0.14), squarely truncate at apex, sides slightly convergent towards 
apex. Median frontal sulcus very short, not extending rearward past 
constricted ends of frontal carinae. 
Mandibles basically of the ordinary ponerine, rather than Myopias- 
like, form, triangular and strongly downcurved, with distinct basal 
and oblique masticatory margins, each furnished with five coarse, 
spaced teeth, the most basal of which, corresponding to the basal 
angle, is subacutely dentiform; apical tooth the largest and most 
acute; masticatory margins crossing over one another at full closure. 
Basal oblique groove and its lateral extension (strix) strongly 
developed. 
Eyes small, round and dot-like, with indistinct facets, only 
0.03-0.04 mm long, and distant from mandibular insertions by 
about 0.20 mm. Antenna massive, scape thick, especially toward 
apex, and overreaching posterior border of head (when held straight 
back in full-face view) by more than half apical scape width; funicu- 
lus with 4-merous club (which takes up more than 0.6 of funicular 
length) following six short, transverse ring segments (II through 
VII); pedicel (funiculus I) about 5X length of II.
