All members of the mexicana group tend to have considerable gray in the body colors, such is not so in triangulum, except some triangulum in the northeastern United States. Lampropeltis ruthveni has a lower ventral count (182-196) than sympatric L. mexicana on the other, is that in the latter two the black rings are edged with a paler color (usually a pale lime green). triangulum on the one hand, and ruthveni and L. ruthveni (within the range of the latter) in having less uniform red rings, often obscured by black pigment middorsally. In addition, this species differs from L. alterna in having the head less distinct from the body.
