Description
Apex nitellopsidoid, with distinct periapical thinning and variable narrowing of spirals, general shape prolate to perprolate, with apex protruded and base tapered, spirals generally smooth, in some species, spirals with wavy or nodular crest, basal funnel present, basal plate thicker than half width, visible from exterior, size small to medium.

WANG, LU, & ZHAO, 1985.]
