I guess the question would be whether or not autonyms were considered=
names. I assumed they would be, although with a somewhat different st=

err ... what would we call the rest of them, anyway?

The only reason we'd need a separate name for the total clade in the =
case of
_Synapsida_ and _Pan-Mammalia_ is for continuity. The total clade has=
been given a name (two, actually: _Synapsida_ and _Theropsida_). On t=
he other
hand, the total clade of _Angiospermae_ (assuming it is made a crown =
clade) has
never been given a name, to my knowledge, so there is no need to set =
up a clade
synonymous with the autonym.

I see. That is a good question. Perhaps it warrants a Note?

It also seems that you could use _Synapsida_ and _Mammalia_, but usin=
_Pan-Mammalia_ and _Corono-Synapsida_ would be pointless. That is, us=
ing an
autonym without using the clade it's based on should be ruled against=
