Menesthella
''Menesthella'' is a genus of very small sea snails, pyramidellid gastropod mollusks, or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the family Odostomiidae. It was originally described as a subgenus of Menestho Möller, 1842 but was erected to genus status by Schander et al. 1999. ==Shell description== The shell is small, broadly conical and imperforate. The surface is marked by strong, equally spaced spiral chords and by fine axial growth-lines seen between the sutures. The periphery of the last whorl is sulcate and the base is smooth. The columella fold (tooth) is strong.
