Diagnosis. Head slightly transverse in anterior view, with one discontinuous crest composed of blunt teeth running between the posterior ocelli and the anterior one; clypeal margin straight and narrow; each funicular segment with one row of sensilla; clava brown (Fig. 28); distal tooth of mandible sharp.
