If you have a subfamily Segnosaurinae within family Therizinosauridae, ICZN 
rules specify that you must also have a separate subfamily Therizinosaurinae 
to contain the genus Therizinosaurus if it is excluded from Segnosaurinae. 
(If Therizinosaurus were included in Segnosaurinae, then Therizinosaurinae, 
which has priority over Segnosaurinae, would becomes the name of the 
subfamily.) Therizinosaurinae would exist even if Therizinosaurus were the 
only genus in it.
