Head in full face view moderately elongate, oval, wider behind than in front, posterior margin widely convex. Eyes moderately large and convex. Mesosoma stout and evenly convex in profile. In dorsal view pro- and mesonotum distinctly transverse; propodeal dorsum somewhat longer than wide. Pronotum laterally weakly marginate and armed with two small diverging teeth; the margination incomplete and somewhat difficult to see even because of sculpturation and pubescence. Mesonotum and propodeum immarginate. Propodeal dorsum with two faint posterolateral ridges at its posterior corners, medially propodeal dorsum and declivity confluent in a blunt curvature. Promesonotal suture slightly impressed, metanotal suture faint. Petiole with a dorsal pair of widely separated, moderately long and diverging spines and a pair of lateral sharp teeth; the space between dorsal spines straight. First gastral tergite anteriorly weakly concave.</paragraph>

look very similar, and share some important features: 1) a shallow clypeal lobe; 2) relatively long scapes, SI> 150; 3) abundant pilosity on body and appendages; 4) mesosoma completely immarginate or almost so; 5) propodeal dorsum and declivity separated by a pair of small, more or less developed, ridges; 6) petiole armed with a pair of moderately long median spines and a pair of lateral much shorter teeth; 7) rough, mostly irregularly longitudinal rugulose sculpturation on head and mesosoma; 8) Body coated with abundant, relatively short and moderately dense greyish pubescence never hiding the sculpturation.
