All are linked together with fine axial striae. The body whorl is round in two adult shells. The sculpture continues on the base with 11 equally spaced spiral ribs. The umbilicus is white colored, open and small. Columella with a tendency to form teeth. Base color brown to olive brown with a pattern of pale flames that runs all over the shell.

Interchangeable taxa

Gibbula eikoae n. sp. is here compared with G. houarti n. sp. Readily distinguished by the shape of the shell which is stepped in G. houarti n. sp. and globose in G. eikoae n. sp. The sculptures as well as the base colors are completely different.
Gibbula eikoae n. sp. is a rare species. We could only obtain the type material in 3 years and thousands of dredging.
