Material.—One cranidium, thoraco−pygidium, and free cheek (repository numbers: NIGP−152046, 152051, 152055).
Remarks.—The cranidium differs from other co−occurring Vietnamia species in having a very strongly developed intermediate lobe, more strongly depressed sagittal area between most strongly elongated (tr.) L1, relatively longer (sag.) preglabellar area, and more laterally convex posterior half of anterior branch of facial suture. The pygidium also differs in having shallower inter−ring furrows and pleural furrows.
