Cephalon ovoid, nearly oval, with external and internal rims curving strongly adaxially. Glabella broad, crest rounded with fine granulation and pitting, and axial furrows convex. Alae anterolaterally directed and eye lobes located away from axial furrow. Brim straight to slightly concave in profile, gently sloping and with large brim perforations (diameter around 220 μm on standardised brim). Well-developed caeca on brim and genal roll. Length (exsag.) of genal prolongations over 90% of cephalic length (sag.).

Cephalon widest halfway between eye lobes and alae, genicranium moderately narrow, widest at posterior border. Glabella broad, only slightly tapered anteriorly and not carinated or inset. Flanks convex with fine granulation and pitting along crest. L1 inflated, S1 slanting anteriorly, effaced before curving forward near crest. Preglabellar furrow distinct and straight in anterior view. Occipital furrow deep and medially straight (tr.). Occipital ring not medially broadened, same width (sag.) as posterior border (exsag.) and, in lateral view, same height as glabella anterior to S0. Tubercles on occipital ring not prominent but closely packed. Occipital node small, located on anterior slope of occipital ring. Alar furrow anterolaterally directed, small, under 30% of glabella (tr.) at S1 and nearly as wide (tr.) as long (exsag.) at axial furrow. Alar furrow shallow but well defined. Alar depression present and axial furrow partly effaced at junction of ala and L1. Posterior border moderately short (tr.) and preglabellar field wide.

Anterior eye lens slightly larger than posterior lens and central lens, which sits between and slightly higher than other two lenses and is much the smallest. Anterior and posterior eye lenses oval, central lens subcircular. Eye ridge not well-defined. Inner margin of fringe across anterior of genal area straight and marked by larger perforations across anterior boss. Boss barely inflated and not joined to glabella or reaching girder. No girder kink. Genal roll moderately gently sloping anteriorly, laterally steep and with caeca. Perforations smaller than on brim with a single row of larger perforations above girder.
