I do not formally recognize intermediate ranks like subfamily---I
simply code them as a clade within the family. And I think I am probably
already skating on thin ice by including Scelidosaurus in this family
(rather than as a separate plesion as I did before), so I am not ready to
put Scutellosaurus in there as well (but I will think about it).
Here is my first stab at how I might code ankylosaurids (other genera
would be added as I studied the family more carefully):

Well, I guess that answers my question. Perhaps you should put the
subfamilies into your chart (Ankylosaurinae, too), just to make sure
knows what's going on.
You might want to include a Scutellosaurinae in Ankylosauridae sensu lato,
too. The scutes of Scutellosaurus are tiny but otherwise strikingly similar
to those of ankylosaurids sensu stricto, and it's merely a very basal
ankylosaurid that doesn't warrant a family of its own.
