Trapdoor Spider

Dear Mysticz,
This is a gorgeous Spider.  It has such a distinctive appearance, including the red tips on the legs.  We could not locate any exact matches on the internet, but we did find this image on FlickR of a Tube Trapdoor Spider from Singapore that looks somewhat similar.  We are quite confident your individual is a Trapdoor Spider, but we are not certain to which family it belongs.  The closest visual match we could locate is a posting to Encyclopedia of Life of
Idiops constructor, a member of the family Idiopidae, which Wikipedia calls the Armored Trapdoor Spiders.

Thanks for the effort Daniel.

Hi Bugman,
Ok, came home after Thanksgiving dinner with the family to find this large spider/tarantula on the wall next to our garage door. It was around 2″ long, healthy, and didn’t seem to be aggressive at all. Temp was in the 50’s, warmer than normally this time of year. We do have some Tarantulas nearby, but this one seemed a bit different.
I can’t easily ID it but after some online searches have narrowed it down to these candidates:
Wolf Spider (Schizocosa mccooki or Pardosa ramulosa)
False Tarantula (Calisoga longitarsis)
California Tarantula (g. Aphonopelma)
Any ideas?

False Tarantula

We are going to go with False Tarantula in the genus Calisoga which is pictured on BugGuide.  According to BugGuide, there are:  “5 species, all essentially California endemics” and their range is “Kern County north to Shasta County, Coast Ranges + Sierra Nevada. Some isolated populations in western NV.”  Now we wonder if any of the spiders from California we have identified in the past as Tarantulas might actually be False Tarantulas.

Thank you Daniel! Was leaning towards this. We have found this spider a few times, but the first was on a box we had in our garage… that was coming from China. My first concern was, of course, an invasive species. We do have Zoropsis spinimana, an invasive Mediterranean Spider (http://ipm.ucanr.edu/PMG/PESTNOTES/pn74143.html) that is being watched, but is apparently not a danger to the local indigenous species. This was a strong contender when I looked up some images, but think it may be too small for my visitor.
Stay Well,
Gregory

This is indeed a Tarantula.  The only species reported from Utah on BugGuide is Aphonopelma iodius.

Greetings! Long-time reader and fellow entomomaniac here. I have a friend who found this fellow around her home in East Texas in September. I’ll admit that my arachnid knowledge is lacking; my best guess was that it was a juvenile tarantula that had recently molted, but that’s as far as I’ve gotten. Any assistance would be greatly appreciated!

Trapdoor Spider

Dear Dani,
This is not a Tarantula, but it is a Trapdoor Spider that is classified along with Tarantulas as a primitive spider in the infraorder Mygalomorphae. We will attempt to provide you with a species identification.

Daniel,
Sounds good! Thank you very much for your help!

Found it dead in the pool. Just curious what it is and if me and my guests need to worry. Legs outstretched it was about 4″ from… toe to toe? And torso was around 1.75″ long.

Male Trapdoor Spider

Dear Mike,
This is a male Trapdoor Spider, probably in the genus
Ummidia, and they are not aggressive.  Male Trapdoor Spiders wander in search of a mate and males are frequently found drowned in pools.
