Gibbula is a genus of small sea snails, marine gastropod molluscs in the subfamily Cantharidinae of the family Trochidae, the top snails.
Affenzeller et al. (2017) have shown than several Mediterranean species hitherto assigned to Gibbula were forming a separate clade and should be assigned to the genus Steromphala. They included in the restricted Gibbula clade the species G. magus (type species), G. fanulum and G. ardens. However many other species were not taken into account in this paper and will remain listed in WoRMS under Gibbula until their phylogenetic position is assessed, but possibly do not belong to the restricted Gibbula clade.
The species in this genus occur through all seas, except on the coast of the American continent.
The cyrtoconoid (= approaching a conical shape but with convex sides) shell is usually perforate or umbilicate. The spire is moderately elevated. The whorls are often gibbous or tuberculose beneath the sutures, smooth or spirally ribbed. The last whorl is generally angular at the periphery. The aperture is subrhomboidal. The columella is oblique, dentate or subsinuous at the base. The outer lip is acute. The central tooth and the lateral teeth of the radula have well-developed denticulate cusps. The outer lateral teeth are wider.
Species within the genus Gibbula include.
