Which specific rat snake population was once nested within P. obsoletus but is now recognized as Pantherophis spiloides?
Answer
The Gray Rat Snake
The Gray Rat Snake, currently identified by the scientific designation *Pantherophis spiloides*, was historically included or nested firmly within the broader classification of *P. obsoletus*. This distinction highlights the core issue of the species complex, where snakes sharing morphological similarity across North America were treated as conspecifics. The recognition of *P. spiloides* as a genetically distinct entity, usually associated with northern or northeastern US regions, represents one of the key revisions facilitated by modern genetic analysis, distinguishing it from the western and black rat snake forms.
