If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

R. Feist and K. J. McNamara 2013Glabella 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).
