Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. R. Westrop and E. Landing 2025 | Palpebral lobes large but shorten somewhat during holaspid ontogeny from length (exsag.) equal to about 50% of glabellar length (e.g., Figs. 8b and 9a) to 41% of glabellar
length (e.g., Fig. 8a). Pygidium elongate, and lengthens (sag.) by posterior extension of marginal spines during holaspid ontogeny.Median embayment of posteriormarginwell defined in small specimens, becoming longer (sag.) during ontogeny, with posterior corners becoming increasingly spinelike. External surface of cranidium granulose, augmented with terrace ridges on frontal glabellar lobe and margins of L2–L4. External surface of pygidium with scattered coarse granules, most closely spaced on axis and adjacent part of pleural field, but become sparse on pygidial spines; subdued over entire surface on largest specimens. |
