Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| V. Jaanusson 1957 | Unisulcate, with a distinct adductorial pit. Some species with a flattened, indistinct ventral lobe, a ridge around the ventral part of the sulcus, and dose to each cardinal corner with a low, rounded dorsal plica; other species without any conspicuous elevations on the lateral surface of the domicilium. Tecnomorphs with a frill-like velar flange, velar ridge, or without a velar structure. Heteromorphs with a strongly convex velar dolon; the inner part of the lateral surface of the dolon lies almost at the same leve! as the general lateral surface of the domicilium, and has usually also the same type of ornamentation . |
