Tubospirina is an extinct genus of fossil sea snails, marine gastropod mollusks in the family Craspedostomatidae.

[citation needed] They lived in the Silurian Period, Pridoli Age (from 418.7 ± 1.5 to 416 ± 2.8 mya).

[2] The genus Tubospirina is very similar to the genus Spirina, but it can be distinguished by the dextrally coiled shell with a flatly arched upper side.

The shells are large, with a wide aperture and a characteristic ornamentation of rounded costae and interspaces.

[2] This genus has been found in the Silurian of the Czech Republic.
