A second test of the new specimen, SC 332466, as a unique taxon along with others sampled from all other known pterosaurs (including Austriadactylus) nests it as THE basalmost pterosaur, two nodes away from Austriadactylus. Any other nesting adds at least six steps. A forced nesting with Austriadactylus adds 10 steps.
That doesn't mean it's a separate taxon, though. Ontogeny, sexual dimorphism, yadda yadda will do that to you.
But that's just a general comment on your method, not on your result. I haven't seen the paper yet.
