Sistrurus tergeminus edwardsii Kubatko, Gibbs & Bloomquist 2011 [by implication] |
Other common names:
edwardsii: Desert Massasauga
tergeminus: Prairie Massasauga
Remarks:
Kubatko, Gibbs & Bloomquist (2011) separated catenatus from its two former subspecies, tergeminus and edwardsii, but without actually using the combination S. tergeminus. However, this name is the one which must be applied for the Western Massasauga, since tergeminus is an older name than edwardsii.
