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_.
