Lissomphalia bithynoides is a species of sea snail, a marine gastropod mollusk in the family Skeneidae.
Description The thin, whitish shell is narrowly umbilicated. Its maximum reported size is 1 mm. The fine growth lines are crossed by microscopic close-set spiral strife, giving the surface a frosted appearance. The 3½ whorls are rapidly increasing. The body whorl is tumid. The peristome is continuous, but partly adnate.G.W. Tryon (1888), Manual of Conchology X; Academy of Natural Sciences, Philadelphia (described as Cyclostrema bithynoides)
