See text Gymnobela is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.

[2] 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 (a synonym of Gymnobela yoshidae (Kuroda & Habe, 1961) )[3] This genus is highly diverse.

[4] The rather solid shell is in form and general appearance like Bela.

The posterior notch of the lip is shallow and usually not very distinct.

[5][6] Fossils have been found in Pliocene strata of Panama and Quaternary strata of Costa Rica (age range: 3.6 to 0.781 Ma).
