Will this be your first scorpion? Not only does the genus Parabuthis have some medical significance, some species can spray their venom which can be dangerous if it gets in your eyes. Not a genus to be kept by anyone without considerable experience.
If I have misread your experience, please forgive me.
I do not recommend this scorpion genus for anyone with less than 3 years exp. or at least a GT score of 120 (common sense basically. I care not for book smarts on this subject).
If you are VERY experienced, you could go with any of the Parabuthus scorpions you can find, though you obviously should go to a person who keeps the scorpion first (as you have already correctly done by posting this message to begin with). Nothing on your species list really fits the bill as far as exact keeping goes.
Your best bet would be P. liosoma until you have more experience with Parabuthus scorps. Afterwards, you could get more in depth to the genus with P. heterurus or transvaalicus as the common three in the trade go. Do keep in mind, these scorps are more dangerous, though they may not be as potent as Hottentota trilineatus/polystictus (whichever you may actually have) for certain species. I would say P. liosoma because they are generally smaller and do not inject the large quantity of venom such as the other two.
I will give you one word of warning though. Five days ago I put a 3.5-4 inch long locust in with a 2 inch P. liosoma. The liosoma was quickly angered when the locust went mid air, and though the scorp did not have time to release a large amount of venom, the sheer impact sent the locust to the other side of the tank. Immediately it was dead. And this is the one I would recommend more than the other two.
GT score...how to explain...
Well, for starters, you must be able to tie your shoe. If you cannot, please go away from this forum until someone has taught you how. Next, you must know what danger is and how to stay away from it. Sorry, I forgot a lot of people here have never taken the test. Aside from the tasteless jokes,
I have never seen a Parabuthus spray or "spit" venom in any way, though I keep a pair of safety glasses handy just in case I am shown differently. I have seen some VERY upset Parabuthus along with some very large and aggressive prey. If I ever do, I'll make sure I video tape it, otherwise, I'm just going to keep my mouth shut about it. Until it is caught on tape, nobody will have any faith in the person who says it anyway. If it is possible, it would take a lot of energy out of the scorp to do it and therefor scorps would do it few and far between, rather than every time someone tried to test the scorp. Faithless people ignore the thought because they cannot believe in what they do not see (no, I'm not refering to religion... *lol*).
Steve055, I believe it was, said that he saw a Parabuthid spit venom in a documentary a month or two ago. As for having faith, if Polis said they do, I'm willing to take his word for it (and, concequentialy, the word of the articles he referenced).
It appears as though you and I both share the intelligence of having faith in the words of another peson. I call it common sense because it simply keeps me out of trouble. Well stated and thank you for the reference of who the person/persons were who stated it in the past and more recently.
Yes it was me that saw the parabuthis projecting venom, i wish i could find out what show it was on. It was a short 5 sec clip at the very begining of the show. It was a Parabuthus transvaalicus spaying vemon at what looked like a large assasin beetle.
Intruiging enough, steve055.
If you do happen to see it again, try to get info on which show it was. I'd like to see that. Heck, I'd order the friggin video from the network, just to watch it. Twould be the scorpion highlight of my month! heheh...
PS: I like the pic you have under the name. Nice way to combine scorp and T/ spider. =D
