Another interesting change: prasina and frenata weren't retained in any of the new or old ratsnake genera. During initial testing their DNA was so different that they weren't used as even a close relative. Ptyas mucosos was selected over either one of them as an outgroup to compare to the rest of the ratsnakes in the study. It was speculated that frenata and prasina may be akin to Gonyosoma.
One other interesting statement was that the species previously separated into the new genus Coelognathus (helena, radiatus, subradiatus, flavolineatus, etc.) would be shown in an upcoming study to be akin to the old world racers (Colubrini) instead of ratsnakes.
