| D. K. Brezinski 2000 | Glabella mildly laterally inflated in the frontal lobe, nearly as wide between ???? as the width at L1, broadly round- ed in the frontal lobe, meeting margin at sagittal line. Small L1, isolated from glabella, suboval in outline, not extending behind base of glabella, separated from glabella by shallow, broad S1. Posterior facial sutures with very short straight section. Lateral cephalic border narrow, flat, sharply rounded at margin, extending posteriorly on to a short genal spine.
