Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. Fillion and R. K. Pickerill 1990 | Rusophycus with very regular, deeply impressed and
clearly separated scratch marks. V-angle is 90 degrees. Scratch marks are bunched in twos but this does not interfere with their regular appearance. Criss-crossing may produce a faint rhombic pattern. Genal spine ridges absent. |
