Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. R. Westrop and E. Landing 2025 | Librigena with broad, strongly convex border; firmly impressed border furrow. Genal spine incompletely preserved, but likely long and robust. External surface of cranidium and librigena (aside from furrows) coarsely granulose; granules typically developed over background of minute punctate (usually visible only under high magnification). Paired fixigenal tubercles defined most clearly on smaller sclerites; additional small tubercles present on anterior border. Some granules of librigenal field arrayed along caecal markings. Pygidial outline roughly elliptical; anterior margin curved strongly backward along wide (tr.) articulating facet. Coarse granules of external surface match cephalic sculpture. |
