|Distribution||USA (Florida: Sarasota County, S Alabama, SE Mississippi)|
Type locality: Mill Terrace and Riverwood Avenue, Sarasota, Sarasota County, Florida, USA (27.29291° N, 82.52453° W, datum WGS84).

|Comment||Distribution: Gulf coast Populations have been previously considered as D. couperi, but found to be genetically (and slightly morphologically) different from D. couperi. See map in Krysko et al. 2016: 561 (Fig. 7).|
Diagnosis. Drymarchon kolpobasileus sp. nov. is distinguished by a suite of morphological features including relatively shorter and shallower head dimensions, relatively deeper and shorter 7th infralabial scales, and shorter temporal scales (Fig. 5). Overall, the presence of a deep 7th infralabial scale provides the best univariate predictor of D. kolpobasileus sp. nov. (Table 3). Based on both DNA (Krysko et al. 2016) and morphology (specimens examined in this study) this species includes populations from the panhandle of Florida southeastward along the Gulf coast to southern peninsular Florida, including the Florida Keys.
|Etymology||The Greek kolpo (meaning Gulf, referring to the Gulf of Mexico) and Greek basileus (meaning King) is used to form the composite noun kolpobasileus (Gulf King), which is applied as a noun in apposition to the generic name Drymarchon. When sea levels were lower during the Pleistocene, D. kolpobasileus sp. nov. was the largest known snake inhabiting the subaerially exposed Florida Platform that extended much further westward than today. This species is still the largest native snake and king of the remaining exposed Florida Platform in the western peninsula and panhandle of Florida.|
