Cephalon ovoid in shape, widest just posterior to eye lobes. Genicranium narrow, widest at alae. Glabella inset, flanks tectiform. S1 very shallow and L1 not inflated. Axial furrow convex, converging weakly anteriorly. Preglabellar furrow bowed upwards in anterior view. Occipital furrow deep, medially straight in dorsal view, and very broad (sag.), broader than posterior border (exsag.). Occipital ring same width (sag.) as posterior border (exsag.) and, in lateral view, same height as glabella anterior to S0. Tubercles present on dorsal surface. Alae laterally directed, broad, width (tr.) same as length (exsag.) at axial furrow. Alar furrow shallow, well defined and alar depression present. Preglabella furrow wide; genal area with fine pits. Eye lobes oval, large (exsag.), ≈43% of width of glabella at S1, and inflated. Genal ridge present, and narrow eye ridge well defined. Anterior boss inflated and joined to glabella. Inner margin of fringe barely concave across anterior of genal areas.

doctoral thesis, but it has no S1 furrow, eye ridge or caeca on the genal roll, and it has a much lower brim width ratio. Also, the inner margin of the fringe passes well away from the eye lobe, while in the case of the material described in the thesis, the inner margin of the fringe passes immediately below the eye lobe.
