We follow Pyron and Burbrink (2009) in the generic placement of this complex, which is represented in the Southwestern region by two taxa. Although a convincing case can be made for placing this complex in its own genus [Scotophis Baird and Girard (Collins and Taggart, 2008)], we feel that retaining it within Pantherophis is currently the more taxonomically conservative stance.
Pantherophis bairdi (Baird's Ratsnake)
Pantherophis obsoletus lindheimeri (Texas Ratsnake) - We feel that this subspecies is sufficiently distinct morphologically to warrant its continued recognition.
