Thanks, saw them for sale and was tempted. Think I'm going to get a couple of the big NW terrestrials first though.
From photos I've seen of the adult coloration, I'm pretty excited. I haven't found any information about their growth, husbandry, or anything else, though so I'll try to remind myself to update here :)

Updating this thread with the latest info:

This species hasn't been the most exciting or interesting species I've kept, but there was an interesting new development last week.

I had rehoused it from the 2.5"x2.5"x6" Herpcult enclosure into a larger 4"w x 4"l x7"h Amac box a few months ago after it molted to over 1.5", and it used and expanded the pre-made burrow a little bit. I molt sexed it as likely male at that time, but not 100% certain.

It has been MUCH more visible since its last molt, when we had a size gain to ~2.5". It has always been a good eater and has been growing reasonably fast, but up until the latest molt, it has stayed in its shallow burrow most of the time and it has not dug much except to expand the burrow to fit its body. After the last molt, it has been much more visible and has stayed out on top of its burrow. It has been showing nice adult coloration for the past two molts, as well.

Last week, he dug downward for the first time. I'm not sure why. He's not always down there, but it's about an inch and a half under the water bowl. I considered that it might be due to the water leeching into the substrate underneath, but I don't think so, because it's too far down, and I always inject water into the bottom of the substrate from the other side.

Really curious to see what he does next!

Pics of burrow and enclosure. I’d consider rehousing into something larger but it seems fine-?

Updates on this species: it sealed itself in completely for a solid month after expanding its burrow and molted. Then it took a while for it to come back out again. Normal spider stuff, just took an unusually long time this time.

Since it opened up its burrow, it has rarely been out during the day and and I'm seeing a lot of the feet while it just waits for food to come by. I think it's cute. It is mildly skittish and maybe about 2.5" dls right now. If it's male, it hasn't matured, but the colors are amazing on the rare occasions when I've seen it out. Extremely striking!

I plan to rehouse it and several other fossorial dwarfs I have, so I'll hopefully be purchasing loads of new enclosures at the Reptile Super Show in a few weeks.

So far this has been an extremely easy tarantula to keep, if not the most exciting, and would be fine for a beginner that likes fossorials (I don't actually know any beginners who would be all gung-ho about fossorials but hey who knows?). Now that the colors have brightened up, I'm glad I got it :)

I'll see if the behavior changes once I move it into a bigger enclosure.

I realized that I hadn't updated this thread since December. Since Tom Patterson is selling slings, I figured it would be wise to update.

In early January I purchased a 6"x6"x10"h top opening enclosure with the intention of rehousing this spider into it as its final enclosure. During the course of rehousing, I observed the ventral area and it looks 100% male to me (open to opinions on this). I had not seen any evidence in previous molts that this spider was female. It did bury its last molt, however.

The spider was at 2.5" dls and I've read that this species reaches 2-2.5" dls as an adult, so I expected that it was a large penultimate male. He's leggy, has kind of a stumpy body, and is absolutely gorgeous
IMG_6261.JPG
In its new enclosure, it did not burrow extensively like it had a few months previously, and instead dug itself a shallow burrow just under the surface against the glass. I have a great view of it.

Roughly two weeks ago, it buried itself. Since it has been raining a lot lately, I was anticipating a molt. Last night, I noticed that it freshly molted - HOWEVER, it does not have emboli. The spider is easily 3" dls, so if this is female, it has a really strange looking ventral area, and if it's male, he's either a monster or the size of this species isn't sufficiently recorded in the hobby.

It looks like he chewed up the molt, but I may try to pull it some time later today.

I've been keeping this species at room temp, feeding one small prey item once a week or once every two weeks depending on the size of the abdomen, and allowing it 6" of substrate to burrow if it wants. It has remained underground 97% of the time. I'm not keeping the enclosure particularly moist, but I am injecting water into the bottom of the substrate like I do with all of my fossorial tarantulas. This has been an easy species to keep.

Side note: He is stupidly pretty.

I found this vid on youtube while looking for husbandry info of this sp. His specimen is waaaaay bigger than 2.5 in of leg span. I think there might be in fact not enough recorded specimen in the hobby.
Really gorgeous and unique spider, I'll be getting one next week! I'll let you know what's up with mine.

Thanks for linking! Nice to see others.

Are you picking up a sling?

Wow! Cool to see! Congratulations! Is it for sure female?

Mine is male. He's not mature yet, but I don't have high hopes of finding him a lady when he matures.

We'll see!

Thanks :happy: Suspected, but still pretty small and hard to tell, I'm not 100% sure. We'll see at the next molt ;)

Agreed, it's a pretty rare specie, must be hard to find other keepers. If mine turns out to be a female, I would be willing to do a 50/50 share breed with you, but we're quite far from each other lol. I really don't have any experience with international shipping.

Update: it's been 2 weeks and mine still hasn't showed any burrowing behavior. She isn't even hiding, she is just hanging out in plain sight all the time. She don't look stressed out and she eat well, I find it really weird since yours has a completely different behavior.

Here is a picture of the enclosure:

That is interesting! Yeah, mine burrowed immediately.

Yep. I have already reached out to people I have found who have kept them. Just was hoping to find someone here!

Do you think it will be useful if I share what I learn here?
Please do! I know this is a bit of a old post, but I'm looking into possibly getting one and would love as much knowledge as possible 😊

The spider isn't mature yet but is certainly male. He's been out more after his last molt, but is still pretty skittish and will usually hide if I disturb the enclosure.

I'll say he's an obligate burrower. A good 4-6 inches of substrate would have been fine for mine.

He's just about 3" dls right now and not mature, so expect a small spider but not tiny.

Getting one a bit over 2" soon. A couple inches of moist sub and a hide from now until adult, from what I gather?

Appreciate any info!

Yeah, pretty much. I'd give between 4-6" of sub but that can be a personal decision, I think. MIne has burrowed 4" down.

I moisten the sub weekly, chuck in a prey item every week or every other week, and it seems fine.

My dude has walled himself up, so I expect him to molt relatively soon.

This *should* be his ultimate molt. If it’s not I will be shocked.

Good luck, little man!

Welp. My dude has molted, and

He is still not mature.

I'm baffled. I know this species is relatively new to the hobby, but I did read on one site (Arachnodien I think?) that they become sexually mature at 2.5". I would not have expected a mature male to get much bigger than that, in that case, but here my dude is, over 3" now (I measured him again in case my eyeballs were not correct, but he's over 3" here, with his legs scrunched up), and there are no signs of emboli.

I'd love it if he has some secret lady parts he's been hiding from me behind a facade of visible epiandrous fusillae, but I am still doubtful that he is female. He's gorgeous, though!

I was hoping that this enclosure would be his last, but at this point, I'm not sure I'm comfortable with his size vs. the enclosure size and may rehouse him again.

Interesting he still didn’t mature!

@Smotzer started a dwarf species thread here. Maybe ask if you want to share/post your husbandry for this species there. Not sure if the overall plans for that thread but looks like some photos have been included of various dwarf species which is awesome.

Yes I’m planning on posting some general care for the genera on the list!

See, people do read your threads. 😁. And just in case there’s FAQ’s...”No”, “Yes”, and “Wait” are all copyright responses with credit to @viper69 😆
Yeah, I’ll wait for him to chime in with those!! ;) :rofl:

See, people do read your threads. 😁
Wait and who said people don’t read my threads!? Lol. I feel like I’m missing something or forgot a conversation we all had on here?

Ha! I was checking if you were paying attention, aka giving you a hard time.
