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" , "Theta" and "Speoides yoshidae" (a synonym of "Gymnobela yoshidae" ) This genus is highly diverse. It is rather an artificial assemblage of several unrelated genus-level lineages that are unrelated and mostly undescribed. Description. The rather solid shell is in form and general appearance like Bela. The spire is generally rather short. The body whorl is swollen. The whorls are often shouldered. The sculpture is rather strong. 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. Fossils have been found in Pliocene strata of Panama and Quaternary strata of Costa Rica (age range: 3.6 to 0.781 Ma). Species. Species within the genus "Gymnobela" include:
