This thread is a very nice addittion for these inverts that don't get that much publicity.

Here are a couple more pics.

cool pics!

Ganoderma · 11-13-2006, 05:24 AM

How in the heck did you get those pics? were against the glass? amazing! All mine managed to burrow in the middle of the cage...

is the article you are talking about by Jack Brookhart? I am waiting for that one, but thought it was about Solifugae, no?

Nikos · 11-13-2006, 08:15 AM

Here is a pic I posted before but since this is an Uropygi specific thread I think it deserves to be included

Here is a big copy of the same photo with lots of detail available in case someone needs it.

@ Mike I love your photos and especialy the 4th one!! simply amazing!!

Goliath · 11-13-2006, 08:41 AM

Ganoderma,

Thanks and she burrowed from the middle of the cage all the way down to the bottom glass at the back of the cage.

The article I am talking about is one I wrote on breeding M. giganteus, it should be out soon in Invertebrate magazine.

rex_arachne,

Thanks.

vardoulas,

Thanks and awesome picture. I love it when they do that, great shot of it. I like the fourth one too, it reminds me of a cave in a bad science fiction B movie.

Thanks,
mike

Ganoderma · 11-13-2006, 09:39 AM

is the fourth one a cage with plants? are those roots? happen to have a full enclosure photo?

Is that magazine available singly? i will take a look and see what its about

thanks!

EDIT: for some reason i cannot edit my first post...anyone know why? i can edit others. anyway i wanted to add links to the first one to keep it organised. her eit is anyway.

This one has some pics and such, but its in spanish. http://www.bloobook.net/browse/arachnida.php?lg=es

not too usefull but provides some info on new chinese sp. http://www.wanfangdata.com.cn/qikan/...003/000309.htm

Well great news for me today! my T. crucifer eggs hatched!!! its 2 am and no signs of any sleep...here is a picture, also check my other thread on these guys. i am pumped!!!

They took around 16 days to hatch at a temp of around 25-27 during the day and down to about 20c at night. This female had not dug out a hide despite being in the container for over 2 months.

Nikos · 11-13-2006, 05:43 PM

16 days only????

Goliath · 11-13-2006, 07:34 PM

Ganoderma,

Fist of all congrats!

I can't believe it was only 16 days, that seems really quick, but it is a tropical species so that may play a big part.

The fourth picture of mine is the babies hanging from the roof of the cork which she made her burrow around. The whips/flagella are what are hanging down.

Usually the magazine comes as a subscription but it maybe sold individually. Check at http://www.angelfire.com/oh3/elytraandantenna/.

Thanks,
mike

Ganoderma · 11-14-2006, 02:31 AM

yes it was quick i was very surprised as well. they were laid on October 29th. hatch date was November 13th. counting both days that’s 16 days. Now the question is how long till they shed? how long till they separate from the mother and how long till maturity. anyone know? i am starting to second guess the species ID. T. crucifer in one paper i read says the type specimen was from Thailand, but other sources say Taiwan and china. I am wondering if perhaps there is an identification problem? anyone know where i can find keys to the specie level? I didn’t think that crucifer had that big a range. i am wondering if perhaps they are T. stimpsoni?

Jeremy Huff · 11-16-2006, 10:38 PM

Hi All,

I just saw the thread and think it is great to get more info out on these animals.

About the identity of the Typopeltis, if you have a close-up photo of the palps of the male, I could identify it. I will go through my papers to see what the defining characteristics are for the group. If they are from Taiwan though, they are crucifer. T. stimpsoni is from Japan and a few small islands off the southern tip.

The two photos I took to show sexing were Typopeltis crucifer (I think, it was a while ago), but they could have been Thelyphonus...

I have found sand with a little peat to be the best substrate because the like to burrow and damp sand can easily be burrowed into. For M. giganteus I have kept them in large gallon or 2 gallon jars with an angled piece of bark that goes all the way to the bottom. Then I add the sand/peat mix (80/20) and bury the bark. The animal will burrow down and under the bark when they have fully eaten enough for the winter. In every case, I could easily see their chamber through the bottom of the jar. They would plug the burrow and stay down for 5-7 months. Gravid females would lay and eggs hatch and nymphs moult all underground. Only then will they come up to feed. Another interesting thing I found was that after one year the first instars had their first moult. 80 of them shed within two days of each other and they were all in seperate containers.

A bit about longevity - from Justin Schmidt's work with M. giganteus
There are 4 immature stages and on the fith they are mature. It is 1 year per stage, so adults are 4 years old and can live upto another 4 years, but usually only 2 years. In the wild, Justin has found that they have no predators to speak of and die of old age.

For anyone interested I am volunteering/working in Lorenzo Prendini's lab at the American Museum of Natural History. I have done several fieldtrips for arachnids and on our website there are photo logs of many of our trips. You can see many uropygid photos there.

excellent! thanks for the link.

Ganoderma · 11-17-2006, 05:51 AM

Wow great info! i will have more questions surely!

about T. stimpsoni . the reason i mentioned them is because i was wondering how far south they actually went. i was thinking it could be possible for them to reach down here? just a thought...any opinions.

rex_arachne · 11-17-2006, 10:08 AM

would it be possible for this thread to become a sticky?

Jeremy Huff · 11-17-2006, 06:25 PM

T. stimpsonii is distributed from Kyushu in the north to Izena (northern extreme of Okinawa) in the south

T. crucifer is from Taiwan and the Ryukyu Islands as far north as Iheya in northern Okinawa

I don't see anything in the literature about the 2 species being sympatric although they come close.

Hope this helps

Jeremy
