Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. Villier 2001 | Enlarged distal superomarginals trapezoidal in dorsal view, the distal extremity turn abradially; 3 to 6 intermarginal plates for articulation with inferomarginals. The most proximal of these intermarginal faces being much larger than the others. External face with an abactinal rounded and elongated tumidity. Adradial face coarsely ovate with an abactinal rim nearly straight. Ornament with a smooth raised central area well-demarcated from a narrow depressed margin. Superomarginal plates as wide as long, with lateral face nearly parallel. Superomarginals articulate each with four abactinal plates that are tabular, polygonal with an ornament of granule-pits and occasionally a reduced smooth raised central area. External face of the superomarginals has a rounded hump. Profile of the lateral faces varies from rectangular, angular to triangular rand regularly convex. Lateral faces concave with a thickened rim along the external edge. |
