    Default Milksnakes finally reclassified

    7) Recent revision of the Milk Snake’s taxonomy (to be published
    in Systemic Biology in 2014) proposes to create 7 distinct species from the
    current 24 subspecies of Lampropeltis triangulum.


    From Frank Indiviglio

    The Milk Snake, Lampropeltis triangulum, ranges
    from southern Canada through most of the USA to northern South America. Among
    the 24 recognized subspecies we find some of the world’s most
    brilliantly-colored and popularly-kept snakes. A recent revision of the Milk
    Snake’s taxonomy (to be published in Systemic Biology in 2014) proposes to
    create 7 distinct species from the current 24 subspecies of Lampropeltis
    triangulum. While this revision was long overdue, we snake enthusiasts may have
    a hard time adjusting to some of the changes. Black and Andean Milk Snakes, for
    example, are now considered to be the same species as the Ecuadorian Milk
    Snake. Other well-known subspecies that have been eliminated include the
    Honduran, Pale, Big Bend, and Red Milk Snakes.
    Following is a list of the 7 new species and their
    ranges, and details as to which subspecies have been combined to form each new
    species.
