Doesn't matter. If there is a subfamily of the Alvarezsauridae that
includes both _Parvicursor_ and _Mononykus_, then that subfamily must
be called Parvicursorinae.
Parvicursoridae, Parvicursorinae, Parvicursoroidea... all these names are
attributable to
Karhu and Rautian, 1996. Parvicursorinae and Parvicursoridae therefore receive
priority over Mononykinae and Mononykidae as long as _Parvicursor_ and
_Mononykus_ are included in the same subfamily and family, respectively (unless
the ICZN changes the rules). How these clades were and are defined is
irrelevant for nomenclatural purposes.
