Sanz et al. (1995), based on Chiappe (1993), conducted a phylogenetic analysis of enantiornitines based on pedal characters, with the topology (Lectavis,Yungavolucris (Concornis (Neuquenornis (Soroavisaurus, Avisaurus)))). This agrees with the present analysis except that Neuquenornis is an avisaurine instead of a concornithine.

You also regard_Lectavis_ as Pygostylia incertae sedis. Is there no character that can be used to refer _Lectavis_ to the Enantiornithes?
