Platyctenidae is a family of ctenophores belonging to the order Platyctenida.

[1][2] Formerly, Tjalfiella Mortensen was classified in this family[3] but appears now to be a member of ist own family Tjalfiellidae.

[4] World Register of Marine Species (WoRMS) does not list any (remaining) members of the family (as of Nov. 2021), though indicating it as validly published.

[2] Therefore it remains unclear if Platyctenidae might be a synonym of Tjalfiellidae.
