I don't think you're mistaken, Mike; you rarely (if ever) are.
Homalocephalidae would be the valid name of the family, even if _Homalocephale_
is sunk into _Prenocephale_. Similarly, Caenagnathidae is the valid name of
the family that contains _Caenagnathus_ and _Chirostenotes_, even if
_Chirostenotes_ is sunk into _Caenagnathus_.
