Taxonomy

The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[2] categorizes Sinuitidae in the superfamilia Bellerophontoidea within the Paleozoic molluscs of uncertain systematic position with isostrophically coiled shells (Gastropoda or Monoplacophora).

This family consists of the following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

• Sinuitinae Dall, 1913 - synonym: Protowarthiidae Ulrich & Scofield, 1897 (inv.)
• Aiptospirinae Wang, 1980
• Hispanosinuitinae Frýda & Gutierrez-Marco, 1996

Genera

Genera in the family Sinuitidae include:

• Sinuites Koken, 1896[3] - type genus of the family Sinuitidae. Genus Sinuites has large aperture, its outer lip is bilobate. The dorsal side is convex. The umbilicus is closed.[1]
