|---|---|---|
| J. S. Hollingsworth 2005 | An olenellid genus with LA rounded forward, reaching border furrow without preglabellar field. LA approximately equal in width (tr.) to L0; L3 wider than LA. Glabella has distinctly impressed furrows; S2 slightly curved forward. Ocular lobes long, nearly reaching poste- rior border furrow, with distinct ocular furrows; lobes strongly curved with small interocular area. Intergenal spine small, posterlaterally directed, located one-half to two- thirds distance from axial furrow to genal spine angle; inter- genal ridge lacking. Hypostome has five pairs of short pos- terolateral spines. Thoracic axis narrow, less than twice the width of adjacent inner pleural region. T15 has a large axial spine; two thoracic segments posterior to T15. Pygidium elongate. |
