Polemicella is a small genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks in 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
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.
