Anterior clypeal margin weakly projected, forms a small rounded lobe. Eyes comparatively small: head 4.4 times longer than maximum eye diameter. Frontal carinae short, divergent, reach the anterior margin of eye. Scape does not reach posterior margin of eye; head 3.5 times longer than scape. Mandible triangular, with 5 massive blunt teeth. Most part of the head brownish yellow, anterior part of head and spot near ocelli more dark, mandibles dark brown.
