|E. C. Stumm 1953||Glabella broad, moderately to highly convex, barely tapering anteriorly. Anterior pairs of glabellar furrows typically obsolete, rarely faintly defined; posterior pair well developed, deeply incised, extending in an axially convex direction from the dorsal furrow to the occipital furrow, isolating two posterolateral, subtrigonal glabellar lobes. Occipital lobes of medium size, elongate, suboval in outline. Thorax with wide, convex axis and convex pleurae having deeply sulcate segments. Pygidium with arched axis and highly convex, distinct segments. Entire test heavily tuberculate, tubercles on pygidial segments in two parallel rows.|
