Faubelidae is a family of flatworms belonging to the order Acotylea.

[1] The family Faubelidae was previously under the name Notocirridae, named for its type genus of Notocirrus Faubel, 1983.

However, a separate genus of polychaetes under the same name already existed, being Notocirrus Schmarda, 1861; this made Faubel's Notocirrus invalid under the International Code of Zoological Nomenclature, being a junior homonym.

With this, Faubel's Notocirrus was replaced with the eponymous Faubelus by Hüseyin Özikmen of Gazi University, who further proposed the replacement of Notocirridae with Faubelidae for this reason.
