Masticatoiy margin of mandible with five teeth ar- ranged as the strongest apical + the sec- ond strongest preapical + a diastema + three small denticles of similar size; the length of diastema is about equal to the distance covered by three small denticles. Basal margin of mandible lacking a tooth- like prominence. Clypeus depressed, with a short median carina that does not reach the anterior clypeal margin but runs through the frontal area.
