    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.

    Eastern Milk Snake, Lampropeltis triangulum
    Former subspecies included:
    Red Milk Snake, L. t. syspila,
    Louisiana Milk Snake, L. t. amaura (population in NE
    Louisiana)
    Range: Ontario and southern Quebec south to North
    Carolina, northern Georgia and northern Alabama and west to eastern
    Minnesota.

    Central Plains Milk Snake, Lampropeltis gentilis
    Former subspecies included:
    Louisiana Milksnake, L. t. amaura (western
    population)
    Big Bend Milksnake, L. t. celaenops
    Pale Milk Snake, L. t. multistrata
    Utah Milk Snake, L. t. taylori
    Mexican Milk Snake, L. t. annulata (central
    Texas)
    Red Milk Snake, L. t. syspila (Nebraska, Kansas and
    Oklahoma)
    Range: North Dakota and Montana to Arizona, Texas
    and western Louisiana.

    Scarlet Kingsnake, Lampropeltis elapsoides
    Range: Southeastern USA as far north as Virginia and
    Kentucky (east of the Mississippi) and eastern Louisiana.

    Mexican Milksnake, Lampropeltis annulata
    Former subspecies included:
    Dixon’s Milk Snake, L. t. dixoni
    Range: Mexican states of Nuevo Léon, Queretaro,
    Tamaulipas; range may extend beyond these states.

    Atlantic Central American Milk Snake, Lampropeltis polyzona
    Range: Colima, Guerrero, Hidalgo, Jalisco, Puebla,
    Michoacán, Oaxaca, Sinaloa, Sonora and Veracruz, Mexico; range may extend beyond
    these states.

    Guatemalan Milksnake, Lampropeltis abnorma
    Former subspecies included:
    Honduran Milk Snake, L. t. hondurensis
    Stuart’s Milk Snake, L. t. stuarti
    Blanchard’s Milk Snake, L. t. blanchardi

    Pacific Central American Milk Snake, L. t. oligozora
    Range: Southern Veracruz and southestern Guerrero,
    Mexico through Nicaragua and Honduras to western Costa Rica; may occur in Belize
    and El Salvador

    Ecuadorean Milk Snake, Lampropeltis micropholis
    Former subspecies included:
    Black Milk Snake, L. t. gigeae
    Andean Milk Snake, L. t. andesiana
    Range: Eastern Costa Rica and Panama to
    Ecuador; may also occur in Venezuela and Columbia.

    May I suggest an edit to make this block of text into smaller lots of text specific to each new subspecies & the formers that are included in it etc.
    May just be me ? but I find it hard to read in the above format, THX Mark

    lol, ya, I just copied and pasted and that's how it turned out. Thanks Ollie.

    I think it'll get take a while to get used to it but the new arrangement does make sense. Hondurans will still be Hondurans for example, but will be a locality as opposed to a subspecies.

    Can you explain this in layman's terms?

    I looks like most of the names we use are becoming obsolete. But are the current subspecies being merged together or still remaining subspecies of the new species they are listed as? In other words, will Hondurans now just be Guatemalans or a subspecies of Guatemalan?

    Also, I don't see Nelson's Milk snake on the list. My only Milk Snake is a Nelson's, it is getting a new classification?

    To view and order the entire paper, see http://sysbio.oxfordjournals.org/con...yt099.abstract

    I don't know where the nelson's fits into the story, I havn't read the entire story. After searching the reptile-database however it does seem to be very close to the sinoloan, which also isn't specifically mentioned. Nonetheless, it is likely included in the Atlantic Central American Milksnake, Lampropeltis polyzona.

    Recall that all milksnakes were previously considered one species, Lampropeltis triangulum. This included everything from the large, colourfull southern animals, to the smaller, brown and grey eastern milksnakes of Ontario. All of the variants were labeled as subspecies, ie, Lampropeltis triangulum nelsoni. What this study did was re-evaluate the validity of all of these subspecies, lumped together the ones that were the same and raised them to species status. I don't think this study recognizes any subspecies anymore, thus there is no more Nelson's milksnake. However, this is just a scientific paper evaluating taxonomic criteria. As hobbyists, naturalists, field herpers, we recognize locality specific varients. If I have it correct, your Nelson's milksnake is now a locality of Atlantic Central American Milksnake.

    To parallel, think of it like boa constrictors. You have Sonoran boas, central American boas, Columbia boa constrictors, all localities of Boa constrictor imperator, the difference is that boa constrictor subspecies are considered valid.

    Ian, wouldn't the Pacific Central American Milk Snake, L. t. oligozora be a subspecies still?

    lol, I bet that is a typo as Lampropeltis triangulum is reserved for the milksnakes of eastern North America. Having the same species on the Pacific coast of central America doesn't make sense with the following divisions. The Pacific Central American Milksnake would be L. oligozora

    Probably right Ian but then there would be 8 species not 7 as stated in the introduction.
