Taxonomy:
Specimens from Meade and Seward counties differ markedly from other individuals throughout the range of this taxon in Kansas, in the they lack red pigment between the stripes, and have a bright red doral stripe. The Seward and Meade county specimens, along with specimens from adjacent Oklahoma constitute a northern relict population, that is characteristic of Thamnophis sirtalis from west central Texas.
The populations in Kansas are distinct, allopatric (parapatric at best) and there is no evidence of intergradation within or among the two color patterns. Some authors (Fitch and Maslin, 1961; Irwin, 1992) have referred the Meade County specimens to the race Thamnophis sirtalis annectans. Systematic work on this wide-ranging taxon is needed and much anticipated.

Fossil Record:
Pleistocene fossil specimens are known from Jewell County.

Remarks:
Not a target species for this project. However, all records will be kept.
