While I'm not sure if I agree Incisivosaurus and Protarchaeopteryx are
sister taxa, note that they were run as a single OTU, and relevant taxa
Avimimus and Nomingia were not included.
Therizinosaurs are also not included, and these could be important since the
skull of _Incisivosaurus_ in many ways looks like a cross between
_Erlikosaurus_ and _Caudipteryx_.
Senter et al. also have a discussion of support for neoflightless
dromaeosaurids. Of the five characters they examine, at least three seem
ill-suited for a judgement based on parsimony when other characters are not
taken into account. These are asymmetrical remiges, enlarged humeral
diameter and elongate penultimate pedal phalanges.
Something I had overlooked: The distal displacement of metatarsal I, a
character associated with climbing (scansoriality), is also seen in
_Bambiraptor_, as well as microraptorians and birds.
