  Titiscania is a genus of slug-like sea snails, shell-less marine gastropod mollusks in the superfamily Neritopsoidea.
  
  Titiscania is the type genus and also the only genus in the family Titiscaniidae.
  
  The original vernacular spelling "Die Titiscanien" by Rudolph Bergh (1890) was Latinized by Johannes Thiele in 1891.
  
  Excepting some parasitic forms, Titiscania is the only genus of gastropod outside of the Heterobranchia to have secondarily lost its mineralized shell, which it sheds after its larval phase.
