Polemicella is a small genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the family Odostomiidae.[1]


The name Polemicella is not available from Saurin (Annales de la Faculté des Sciences de Saïgon, (1959): 242), who did not explicitly designated a type species ("doubtful OD" according to Schander et al.) [1]

Shell description[edit]

The original description by Laseron (1959) (in French) states that the genus was introduced for forms of the near Pyrgulina polemica: short shell with graduated, streamlined or angled whorls on the periphery. It is sculpted with axial ribs and with a single spiral on periphery. There is sometimes a spiral towards the summit of the whorls. Pyrgulina mellvilli is also a representative typical of this genus.

Life history[edit]

Nothing is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are most likely to be ectoparasites.
