Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Feist and K. J. McNamara 2013 | Glabella narrow subconical, slightly constricted behind anterior third; occipital ring as wide as base of preoccipital glabella; palpebral lobe truncated behind without turning point e, anteriorly with marked inward curvature prolonged by oblique palpebral ridge; posterior fixigenae wide; eye inconspicuous, visual surface steeply sloping and merging with subocular area, periph- erally defined by continuous sigmoidal furrows. Pygidium short, of widely parabolic posterior outline, projection of maximum pygidial width across middle of third axial ring; axis robust, approaching posterior border, with 7–8 axial rings; posterolateral border narrow, slightly inflated, defined by conspicuous border furrow; sculpture: sparse granules, pygidial border with terrace ridges (emended from Feist in Feist and Schindler 1994). |
