There are two main types of spiders:
Primitive spiders (Mygalomorphs) which:
* take in air through two pairs of abdominal pouches called
book-lungs
* have fangs (chelicerae) that work up and down like a pick axe
* do not hang in webs of silk, but may live in silk-lined burrows
and spin egg sacs
* resemble spiders found only in the fossil record from 300 million
years ago
* include the funnel-web, trapdoor, tarantulas and brush-footed spiders.
True or modern spiders (Araneomorphs) which:
* take in air through one pair of book-lungs and through tracheal
tubes
* have fangs (chelicerae) that work from side-to-side like pincers
* can manipulate the silk they produce to make webs and attach
themselves to the web
* include most other Australian spiders.

Reply: I couldn't find much more information on these
spiders. Nice pics, click for a closer view- glen

Hello, Glen. We stumbled across your website and really love it.
We recently found this large spider near the Sarapique River flood plain in
secondary growth lowland humid rainforest, not far from the La Selva Biological
Station of OTS in Costa Rica. I have many more photos than the 4 attached if
it would be helpful to see anything else.
I believe it is a Nemesiidae but would love to get it down to genus or even
species if possible. It is extremely fast and quite aggressive. It is
primarily nocturnal but also comes out in the daytime if lights are not too
bright. It eats voraciously.
Thanks

RAVINE TRAPDOOR SPIDER |
|
Another Reply: The spider with the flat abdomen that was found on august 2, 2010 is probably a Ravine Trapdoor Spider. I have found them many times in Tennessee and they are very common here. The scientific name is
Cyclocosmia truncata.

spider but I have never seen one with this shaped abdomen - very

I am sad I only got one shot of this guy but we were hiking on a small mountain in Wenatchee Washington called Saddle Rock, during the summer and at night. We saw this guy crossing our path in our light. He was big! So we took a picture. I'd say he was probably close to 3/4 of an tall and say 1 1/2 inches from "toe" to "toe". He was a pretty one but none of us had seen anything quite like it before. Any ideas? Thanks! |

Reply: It is not a hobo.
It is some sort of myglamorph, perhaps a trapdoor spider even
though it is a bit light in colour, so I'll include it in this
section as well as the trapdoor spiders. glen

Glen, found this guy crawling on my buddy at work last week (Southern Idaho). We both thought it is a Hobo. Over the next few days, we saw 5 or 6 more just like it. They are rather large at about 1 1/2 inches long. Please let me know what it is.
Thanks,
Ken

Hello Glen from Texas!
I'd like to start with I love your website! We just bought our first home and it helped us identify the Wolf Spiders that we've been finding by dozen! It's a new construction neighborhood so I know we'll have plenty of finds as they continue digging up the lot next to ours. I found two of these guys on our back patio this morning though and I'm not quite sure what they are. I had to keep our 7 week old puppy from playing with it! I took him in the house and went for my camera and when I came out this guy was 'playing dead' I got real close and personal and started snapping away and mid photo-shoot he got up and wandered off! Please help!
PS I'm an amatuer photographer (HAHA) in training so my photos aren't as beautiful as most of the ones from your readers! :-)

Hi Spiderzrule,
My name is Tarni, and I live in a small town called Waubra.
I found this spider (see pic attatched) just outside the back door of our house, after dark, on the concrete. We had recently had decent rain, after a lenghty period without any, so I am supposing that may be why it was so close to the house. If it helps we have volcanic soil, and numerous cypress pines, which keeps the soil moist. Can you please identify it if you can and let me know what it is. We have plenty of them here, but I can find no one who can tell me what they are.
Thank you for your time.
Yours Sincerely, Tarni

Reply: It could be an Australian Tarantula - one of
the trapdoor varieties.

Hi Glen we have just found this one in our house. It is approximately 10 to 15 cms long. We are on the north part of the Atherton Tablelands in far north Queensland. Never seen anything like this. Can you please help
Regards Krish

Hello, I had a look on your website but
could not find this spider. We found it
on the Finke River Dirt Road in NT,
about 300km West of Alice Springs. It
was huge! and of course all ran for
miles but thought we should get some
photos to prove the size of this thing,
we all thought it was something out of
Archnaphobia, hehe. Can you please ID it
for us?

Hi Glen, I regularly check out your photo page to
see if anything new has been posted and noticed that
you have not put any new photos on since October,
2006. I dont know whether this is because you have
not had any submissions or you have discontinued
updating the page. So, in case you are still in the
business of posting new photos, I am sending you a
couple photos of Mygalomorphae for which we have had
some difficulty obtaining positive identification,
There is some suggestion that they are species of
Trapdoors. So maybe if you post them on your site,
some body may see them and come up with a more
positve answer. You have to admit, they are not what
you would call attractive ladies.
Regards, Col Halliday

CYRTAUCHONIIDAE |
16 June, 2003:
Okay then, first up, the very cranky Mygalomorph I found in
Baja California, Mexico. My biologist friend, with whom I've been
working on a local spider survey, tells me I'm partially right about
the ID of this spider. It IS a Mygalomorph, but not a trapdoor
spider. He says, " Your mygalomorph is a member of the Family
Cyrtauchoniidae. That's a mouthful. They were once classified in the
trapdoor family but were recently split. They tend to burrow into
sand dunes. I have found them when digging for sand dune spiders,
Lutica. The family needs revision in a big way. There are apparently
several undescribed genera and species waiting for someone to work
up." We found this guy all rolled up playing dead in the dirt. It
came to life when I got my camera out, and put on a rather
unfriendly display of fangs and legs, which allowed me to identify
it as a myg. After annoying it a while, we let it go in a nice bush.
