Mygalomorph fooled me

Tonight, I discovered a mygalomorph inside my bedroom. Fair chance that it was the same one that escaped about a week ago. I put him inside the same temporary plastic container and he's not happy. He's constantly standing up on his back legs against the side - trying to get back out. This time, Ive put 2kg of weight plates over the top. And there is an air hole in the middle of the top.

Nice.

Why don't you make him a temporary reusable home from a common tupperware container.

Just drill a row of small holes all around the rim and add an inch of moist dirt. Perhaps a small piece of bark. Done. You can feed him, give him a drink, photograph him and eventually release him outside to find his femme fatal.

And next time you can just reuse the container.

He may already be a little dehydrated from his stay in your house.

Yea that was my original plan. I do have an aquarium I could use.

Exactly. I gave him some water last night. I also left water out for him in my room while he was on the loose.

and eventually release him outside to find his femme fatal.
I do admit that I feel sorry for him. He was pretty restless last night after the capture.

There are some arachnologists who are currently doing a revision of the Anamidae family. I have been informed that what I have is likely an undescribed species and that it would be very beneficial to these guys if my spider was sent to them for their work. As such, I'm really conflicted as what to do. Part of me wants to keep him as a pet in a proper enclosure. Part of me feels sorry for him and wants to release him. And another part of me wants to send him to the arachnologists to help with the revision of this family.

In that case i'd communicate with the researchers some more to make sure they are expecting him and donate him to science.

A new described species may help with conservation efforts in that area.

Yea I'm likely going with that route.

The real question is is this the same Proshermacha from Adelaide Hills or the Crawford Forest species. Both are reasonably close to the island on the mainland. Also, if you can get a lateral shot of the first pair of legs (not pedipalps, but the legs with the modified tibia) I can confirm the genus as Proshermacha with a little more certainty, as Teyl and Prosh have different tibia shapes

I could try to get a side on view of the first leg. Though the plastic container he's in is a bit foggy. I'd have to have him out in the open but I hope he doesn't do another runner on me like the last time he was out for a photo session.

An arachnologist stated that the big spur on this male's first leg is a megaspur. Just wondering if Proshermacha and the Crawford Forest species have a megaspur?

Both Teyl and Prosh have such, but the metatarsus (between the foot and that modified tibia with the spur) is the real helpful thing to examine. It won't tell you much about what specific species it is, but it can help narrow down a genus with a bit more certainty, as different genera have different shapes

The local arachnologist confirmed to me that any spiders submitted for study would be euthanised. I suspected that might be the case and I'm not really happy about that. I don't think I could let that happen with this particular spider. Ive gotten too attached to him. Out of the four mygalomorphs that Ive collected over here in the past 2 - 3 years, this one is the most active. And Ive gone through too much with him with some memorable moments. I think I'll release him. If I find another wandering male, perhaps I will send him instead for the taxonomy.

I will definitely release this guy at night as that is when I found him and the previous spider outside. Though I'm wondering if I should wait until after some rainfall? There may have been a bit of recent rain before I spotted the current spider. Though I don't recall any rain when I collected the previous spider months ago.

Yeah real shame in the age of super technology we gotta kill an invert just to study it .. :( in that case give them a very old mm.. surely they already collect stuff ? No spider doctors 🥼 either ..:sad:

The local arachnologist here has only collected Anamids from another part of the island. Sounds like she hasn't found them in the North East where I'm based. Ive found four of them within my own home. And these ones may possibly be a different species or genus.

in that case give them a very old mm
It would be good if there was a way of telling how old a mature male is. The one I have looks very healthy and can be very active at times. He looked restless last night - trying to get out. I have no idea how much time he has left before he expires.

Prob same wear and tear tarantulas would show , maybe you have a young specimen. They are related although very different .

If you have grown attached and don't want him to be preserved i think i can speak for everyone that we understand that quite well.

As i said i think communication is key. Talk to the Arachnologist and if it isn't a priority right now i doubt it's a problem for you to go ahead and release him.

Or you could try and find a female, place him close by and watch what happens.
Easier said than done though.

That's bullcrap. Expedience. There's a video out there, or several, of milking venom from Atrax and Phoneutria repeatedly without harm. Just need experts with the know-how to catch and handle the spiders properly. One segment of a video showed this woman casually trapping speeding phoneutria and holding them tummy up as they got things set up.

Due to the spurs on the front legs and the fact that it was walking around outdoors at night, I assumed it was a mature male looking for a female.



What kind of wear and tear would old tarantulas have?
yes that’s a mm.
Just same as premolt which most my Ts are going through. If you check my pics the colors are drab and the legs look more worn down .

Oh yea we have communicated. She recommended that I release him if I didn't want to go through with the taxonomic study.

Yea super hard to find a female. I guess there would be one underground in a burrow somewhere. When I release the male, I wonder if I could follow him for some distance and see if he leads me to a female in her burrow.

I'm still not sure if I should release him after rainfall (if that provides optimum conditions.)

I guess there's quite a difference between milking venom and taxonomic study. With the latter, it looks like a very thorough and intricate examination of the body parts.

Here's footage showing Dr Robert Raven examining an Australian tarantula. The specimen is clearly deceased and he does use an electron microscope for some of the work.

Agreed. Some studies require dissection. But there are many examinations that only require close examination and it's much simpler to undertake them from a dead specimen even if alternatives are available.
I'm going to sound like a PETA fanatic here, but putting my way through college working in a lab then as a veterinary assistant I've seen more than my fair share of unnecessary euthanasia. A raid at a stable found 12 severely neglected horses. The vet I worked for conferred with animal control then instructed me to euthanize all 12. Caring for them and finding them homes was too much trouble.
And worse, working in and around the path lab at a hospital, I've encountered more than a few unnecessary surgical procedures. Entire colons removed on a bad guess of a physician and so on. And the crowning glory, reading medical statistics, per capita the state with the most hysterectomies was California. The county with the most was ours, and the most active gynecologist in the county was at our hospital by one physician who often performed several times a week. Her solution to all female problems was hack out the ovaries. The hush hush among nurses, the nickname the butcher given to that doc.
A little more ethics and responsible conduct in both research and remedial care, please.
