Cephalon ovoid, glabella with tectiform flanks. S1 short, sloping backwards. L1 weakly inflated and axial furrows effaced at junction of L1 and alae. Occipital furrow shallow, occipital ring pitted and in lateral view, higher than glabella anterior to S0. Genal area very broad (tr.). Anterior boss joined to glabella and preglabellar furrow effaced. Perforations becoming smaller for a short distance away from girder. Girder kink pronounced. Brim narrowing strongly posterolaterally. Marginal band with ridge top and bottom. Tubercles on dorsal surface of internal rims. Pygidium with four pleurae and tubercles on terminal piece.
