Although I'm not sure if the formal description is out yet, I do believe
that the phylogeny was in:

Sereno, P.C.  (1997).  "The origin and evolution of dinosaurs."  Annual
Review of Earth and Planetary Sciences 25: 435-489.  

I don't have the paper on me right now, to the best of my memory, the
phylogeny ran something like:

Ceratopsia
|--_Psittacosaurus_
+--+--"Chaoyangosaurus"
    +--Neoceratopsia

Someone else might be able to fill in the gaps.  

BTW, anyone here looked at _Stenopelix_?  I may be way off base here, and
I've only looked at photos, but doesn't it look an awful lot like a headless
_Psittacosaurus_?  

Just a thought.
