Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Basse and U. Lemke 2020 | (updated, after Hahn 1967a: 92): Pseudowari bole with following relevant features: Glabella more or less tightly rounded anteriorly, opposite γ and ε narrowing (tr.), longer than wide, with fine granulation dorsally. Pregla- bellar field not developed, or rudimentary (sag.). Upturned anterior cranidial border slightly shorter than occipital ring (sag.), bearing numerous terrace ridges. Palpebral lobes long (exs.), eyes dorsoventrally high. Anterior portions of librigenal fields well-developed and moderately short (tr.). Genal platform indistinct, limited by more or less indistinct ledge distally. Librigenal spines long. Pygidium appears moderately undifferentiated dorsally. Its posterior margin widely rounded. Rachis longer than wide, as wide (tr.) as one flank, and reaching roughly 2/3 of pygidial length, with 7 plus 1 rings followed by more or less indistinct postrachial ridge. Dorsoventrally moderately low-vaulted pleural fields bearing 5 segmental units, anteriormost two of which differentiated as segments. Posterior branches of ribs differ only slightly from anterior ones. Dorsal segmentation generally weaker defined across wide doublure. |
