An SEM of the protoconch can be found in Warén & Bouchet, 1993, p.34, Fig. 26F.
| Size under dissecting microscope: 300-310µm Size under compound microscope: 290-300µm |
| Morphology: This is the largest peltospirid protoconch we have found at EPR. Lineate sculpture, narrowly spaced, covers the posterior half of the protoconch. The anterior portion is smooth. The aperture is deeply sinuous, unlike all other peltospirids we have found. |
| Frequency: Pump EPR 1999-2000: Not collected Pump EPR 2004: Rare Trap EPR 2004-2005: Rare |

Because of its size and distinctive sculpture and morphology, this species is unlikely to be confused with any other protoconch. Rhynchopelta concentrica (pictured at left) is nearly as large, but is quite different in appearance. |
