Gymnobela


Gymnobela is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
This genus can sometimes be hardly differentiated from species in the genera Spergo Dall, 1895, Theta Clarke, 1959 and Speoides yoshidae Kuroda & Habe in Habe, 1961

The protoconch has a fine cancellated sculpture. The subsutural band is not strongly marked. The posterior notch of the lip is shallow and usually not very distinct. The operculum is absent.
