Aphanitoma is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae.[1]
The shell has a fusiform shape. The sinus is scarcely apparent. The biplicate columella is nearly straight. The canal is rather short and slightly curved.[2]
(Original description in Latin) The shell exhibits a fusiform shape. The body whorl is slightly depressed anteriorly. The outer lip is essentially linear, exhibiting minimal sinuosity. In adult and intact specimens, it displays a barely perceptible emargination near the posterior suture. The columella is nearly straight, showing two prominent folds that descend along its central portion. The posterior fold is more pronounced than the anterior. Both folds diminish in size within the aperture. The siphonal canal is notably short and exhibits a sinistral curvature.[3]
