Comment Largen (1997) mentions that this species could have been treated as a synonym of P. tanganicus. BROADLEY 1998 (in SCHMIDT’s 1919-1923 SSAR reprint) stated that STERNFELD’s specimens were allegedly collected in Rwanda or eastern Kivu but have never been found in this area subsequently and it is probable that they were obtained at lower altitudes in Tanzania and mislabeled.(1)

This sandsnake was found in the Kalama Concervancy, Central Kenya. And: How do I tell the difference between a link-marked or Tanganyika? And which one is this?
Florian Finke: "Optically Psammophis tanganicus do have much more blotches on the head and often they are more coloured.
