Titiscania is a genus of slug-like sea snails, shell-less marine gastropod mollusks in the superfamily Neritopsoidea.[2][3]

Titiscania is the type genus[2] and also the only genus in the family Titiscaniidae.

The original vernacular spelling "Die Titiscanien" by Rudolph Bergh (1890)[1] was Latinized by Johannes Thiele in 1891.[2]

Excepting some parasitic forms, Titiscania is the only genus of gastropod outside of the Heterobranchia to have secondarily lost its mineralized shell,[4] which it sheds after its larval phase.[5]

Species

Species within the genus Titiscania include:

  • Titiscania limacina Bergh, 1890[6]
  • Titiscania shinkishihataii Taki, 1955[7]
