Spider ID Please

    Sorry, but I'm a total spider noob. As me about millipedes, and we can talk...but when it comes to spiders, I don't have a clue.

    OK, so on Halloween night I found this interesting spider outside my front door. I live in Northern California, in a rural area near Santa Cruz, and I have never seen a spider like this around my area before. From the body shape, it almost appears to be a tarantula...but again, I haven't a clue. Can anyone out there help me ID this little guy? And does anyone know if this is a local California species?

    The spider is about 1 inch in size, and the cage that the spider is in measures 7" x 4", so you can get a visual size reference. The real-life coloration of the spider is a bit more tan in spots, but the picture is pretty close to what he actually looks like.

    Thanks in advance! :)

    It is a Calistoga spider. 90% chance a mature male that won't live long. It would be best to let him go where you found him.

    if youre going to keep him, provide about 4-5" of substrate from the carapace on him it looks like a burrowing sp.

    an uncanny resemblance, but the odds are stacked against finding one wild in Cali.

    Actually from what I've been finding (I found a similar spider recently and have a thread about it on this same board.) it is a Calisoga longitarsus, (note no T in the genus.) In some literature it is referred to as Brachythele longitarsus. I found a common name of "funnel-web tarantula". It is from the family Nemesiidae, which is a "cousin" to Theraphosidae. Both are in the group Mygalomorphae and are large and generally primitive.

    Some pictures of the specimen I found:

    I am going to try and get some photos of them in their natural habitat.
    We're planning a backpack trip over Thanksgiving weekend, and will be keeping an eye out--I have a suspicion of where we will find them and if its right then they have been right under our noses. Apparantly these guys will make a fanlike web with a tube that goes into a burrow. They commonly build these things along cut roads and burms, or the sides of inclines.

    As a note-I find a lot more information on google searches using the spelling longitarsis, versus longitarsus. Im not sure which is correct.

    Thanx PhormictopusMan
    would really be intrested in some pix of their natural habitats :)

    and in the The World Spider Catalog by Norman I. Platnick
    there is indeed note of Brachythele longitarsis
    but also 3 other Calisoga spec. from the US:
    C.centronetha, C.sacra and C.theveneti

    def. intresting spiders !!! :D

    I live in the Sacramento Valley and I was told that C. sacra was probably the ones I have. One funny thing to note about these spiders. If you are going to try and find some in the wild, don't use water to try and get them out of their burrow. They are not like a t and will not come out with water.
  12. PhormictopusMan - I live up in the Santa Cruz Mountains, near the summit (half way between Los Gatos and Santa Cruz). That's where I found the Calistoga spider. He was sitting outside on the front porch one night. Just out of curiousity, where were you thinking you might be able to see these guys in the wild around our area?

    Well right now the males are wandering because it seems to be mating season. My thoughts were to check out some places at Henry Coe State Park, as I have planned to be there anyway. I want to also start checking around the local parks near my home in the Cupertino Foothills. I figure if he wandered into my living room, more of him/her can't be far. I'll also ask some of the local rangers--They usually give me some pretty good information.
