Familia Desmopteridae

Family Desmopteridae Chun, 1899

The Desmopteridae is composed of one genus only.

The shell is completely lost in Cymbuliidae and Desmopteridae. In Cymbuliidae the visceral mass is surrounded by a secondary cartilaginous-like slipper beset with spines or tubercles. In Desmopteridae the slipper-like pseudoconch is absent. The wings, derived from the foot, form one continuous disc in which the posterior footlobe is also incorporated. The proboscis protrudes over this wing-disc. The visceral mass with mantle is found underneath this wing plate. A large mantle gland is absent.
