Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Breton 1992 | Species of large size defined on enlarged ultimate superomarginal plates. Plates large, high, outer face highly but regularly rounded and developed abactinally. Raised central area smothed to covered by granule-pits. Depressed margin relatively large. When partially covered, granule-pits are lacking on the abactinal side. Adradial face ovale, with a slight abactino-distal indentation. Enlarged ultimate superomarginal plates in contact with five to six inferomarginals. |
