5. There's always "Ginnareemimus", the Thai ornithomimosaur without an arctometatarsus. But I would leave ornithomimosaurs "2" until its identity is ascertained.
Does it really lack the condition?
...and also, is it really ornithomimid?
Then *Ornitholestes* (I counted 43 in Glut's Encyclopedia p. 644) comes in, and I have, should I use *Allosaurus* as an outgroup, a synapomorphy of Coelurosauria excluding Compsognathidae. Rather uninformative as long as I have no outgroup.
