Thorax elongate-elliptical, slightly broader than the head; mesonotum as long as broad; base of epinotum convex, decidedly shorter than the subperpendicular, concave declivity. Superior border of petiolar node rather deeply and semicircularly excised. Surface of head and thorax much smoother and more shining than in the worker. Erect hairs on the head and thorax shorter and sparser. Head and appendages reddish yellow; thorax and petiole deep red.
