Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. A. Sundberg and L. B. McCollum 1997 | Oryctocephalinae with cranidium with medially to anteriorly expanded glabella; lateral glabellar fur rows with pits at SI-S3, not extending to axial furrows, typically SI pits connected with transglabellar furrow, S4 pits small and faint; occipital ring typically without longitudinal furrows pro jecting from So depression to the posterior margin; anterior mar gin of rostral-hypostoma plate slightly wider than maximum gla bellar width. Pygidium with typically 5 or 6 pairs of cylindrical spines and moderately developed interpleural furrows. |
