|---|---|---|
| A. R. Palmer and L. N. Repina 1993 | Species of Olenellus with posterior margin of cephalon nearly straight or only slightly angled forward distal to position of intergenal spines. Intergenal spine or swelling generally closer to genal spine than to axial fur- row. Sagittal length of preglabellar field characteristically greater than twice sagittal length of anterior border. Posterior tips of palpebral lobes convergent toward glabella, opposite or posterior to posterior part of Li. |
