Head in full face view subtrapezoidal, wider behind than in front, posterior margin wide and weakly convex with widely rounded posterior corners. Eyes relatively large and protruding. Mesosoma stout, evenly convex in profile. Pronotum laterally marginate, the margination interrupted a little in front of the promesonotal suture; mesonotum and propodeum immarginate. Pronotal teeth anteriorly diverging, relatively short and sharp. Promesonotal suture distinct, metanotal suture weaker and hardly interrupting the sculpturation. Propodeal teeth reduced to minute tubercles. Propodeal dorsum and declivity confluent in a blunt curvature. Petiole with four thin spines, the dorsal pair directed upward and slightly backward and about 1.5 times as long as the lateral pair. Petiolar dorsum in frontal (or posterior) view obtusely angled in the middle. First gastral tergite anteriorly concave.</paragraph>

The smaller specimen does not significantly differ from the holotype. Yet an unexpectedly large specimen has a seemingly stouter mesosoma and pronotal teeth, and stronger petiolar spines (dorsal and lateral pairs more similar in size also). In my opinion, these differences are slight and possibly due to allometry.
