Original Description
Shell urceolate, smooth, very similar to the preceding species; also with eighteen longitudinal ribs, but differing in the larger size of the cephalis and its pores, and in the more slender and ovate form of the thorax. Length of the two joints = 5: 10, breadth = 5: 8. Pores of the cephalis more numerous. Mouth half as broad as the thorax.

Cephalis 0.05 long, 0.05 broad; thorax 0.1 long, 0.08 broad.

Etymology: Latin "costatus" (-a, -um) = ribbed

Editors' Notes
Haeckel listed Sethamphora costata under the subgeneric name Dictyoprona, but did not include the subgeneric name in the species name.
