`Since you cited Utiger et al., you should be familiar with their tree. Their findings show that all species formerly classified in Elaphe, together with the Lampropeltini, form a clade with Ptyas as the outgroup. How can a clade be polyphyletic?'
The clade isn't the group in question, Elaphe is.
`Where is the evidence of polyphyly?'
FWIW, Utiger et al. also cite Minton (1976), Lawson and Dessauer (1981), Dowling et al., and Dessauer et al. (1987) as having concluded that Elaphe is polyphyletic. I can give you the complete citations, if you want.
