Anterior clypeal border with its median third straight and almost lobe-like. Frons relatively wide. Eyes protruding and placed slightly in front of the midlength of head sides. Mesosoma entirely laterally marginate; the margination overhanging the sides. Promesonotal and metanotal groove distinct, especially the latter which is also clearly incised in lateral view. Pronotum, mesonotum and propodeum wider than long. Pronotum with anterolaterally directed strong teeth at its anterior corners. Propodeal dorsum bearing at its posterior corners a pair of very stout upturned and weakly outward directed spines. Propodeal dorsum and declivity mostly confluent. Petiolar node with a pair of strong teeth medially and two pairs of long, mostly straight spines laterally. The spines of each lateral pair diverge: the anteriormost spine is slightly in front and dorsolaterally directed, the posteriormost one arises from a lower point and is more backward tilted.</paragraph>
