Original Description

Very large, robust; low sinistral trochospire, very tight. Equatorial outline circular, very weakly lobate; lateral outline biconvex, umbilical side higher. Chambers angular-rhomboid, very closely appressed, about 17 in total, 6! in final whorl; increase slow. Dorsal view: chambers much longer concentrically, flat; sutures flush; intercameral sutures strongly directed anteriorly then recurved posteriorly 1/3 way to periphery, leaving posterior portion of next chamber extending along peripheral border; distal spiral suture and distal portion of intercameral sutures of final whorl limbate. Ventral view: chambers moderately inflated; sutures radial or curved posteriorly, not meeting because of wide umbilicus. Lateral view: periphery keeled; dorsal side of final chamber weakly convex; ventral face weakly and irregularly convex; umbilical shoulder subacutely recurved close to umbilicus; aperture an umbilical--extraumbilical interiomarginal low slit except weakly raised near periphery; keel thick in early chambers of the final whorl. Wall densely perforate, smooth, but heavily pustulose in early chambers of the final whorl.

Size:
Length, 750 µm; width, 625 µm; height, 360 µm.

Etymology:
Latin, latus, broad, wide; umbilicatus (m.), navel; -us, adjectival termination.
