Identification
Zhou (2001) - Resembles Stigmatomma rubiginoum, but differs from the latter in each side of clypeus with a tooth and the median portion with 4 denticles; frontal lobes well forward, slightly surpassing the anterior clypeal border; anterior face and dorsal surface of the node forming an obtuse angle.

Worker
Holotype. TL 7.7, HL 1.38, HW 1.38, CI 100, SL 0.78, SI 56, ML 1.22, MI 88, AL 1.94, PW 0.91, NW 0.84, NL 0.72.

Head as long as broad, occipital corners and anterior corners of head roundly angular, occipital border concave. Eye small, situated behind the midlength of the sides of head, about .two-thirds the length from the anterior corner to the posterior corner. Mandible more than four-fifths as the length of head, widest at base, the inner border with 10 acute, bicuspid and curved teeth, apical teeth longest, the 3rd smallest, and the remaining teeth are in the same size except the basal teeth which much longer. Clypeus short, the area between .frontal carinae flat, anterior border straight, each side with a large tooth, in the median portion there are 4 denticles, each with the same distance from another. Frontal lobes well forward, slightly surpassing the anterior clypeal border beneath them. Antennal scapes reaching back nearly to the·level of the eyes; funiculi thickened towards the apex; the first segment slightly longer than broad; all the remaining segments broader than long except the terminal segment which about 1. 5 X as long as broad. Alitrunk rather short, sides rounded in dorsal view, mesonotum constrict; in profile view, dorsum flat; mesopropodeal suture distinct; pronotum slightly broader than long; basal face of propodeum subtrapizoidal in dorsal view, slightly longer than broad, broader posteriorly than in front, as long as the declivity which sloping and forms an angle with the basal face; sides of the declivity submarginate, slightly concave in the middle. Petiolar node broader than long in dorsal view, semicircularly rounded in front, with straight and subparallel sides; anterior face slope, dorsal surface straight in profile view, forming an obtuse angle with the anterior face. Ventral border of subpetiolar process bluntly rounded. Gaster stout and long. Sting rather long.

Mandibles, clypeus, frontal lobes finely striate; head, alitrunk and gaster punctate, punctures on head much coarser and with striations among the punctures. Lower half of the declivity of propodeum smooth.

Hairs yellow, short, rather abundant, longer at the apex of the gaster. Pubescence short, fine, more abundant on the gaster.

Color reddish brown; occipital border of head, borders of mandibles and teeth, and dorsum of pronotum darker. Legs lighter.
