Sculpture of head, petiole, postpetiole, legs and gaster as in the soldiers. Dorsum of mesosoma with sparse foveae, space between foveae microalveolate. Propleura deeply striate. Anepisternum deeply and denselyfoveate, withoutspacebetween foveae; katepisternum and metapleura finely rugose with some sparse foveae (Fig. 7b).
