Xenesthis immanis Female Colors

[WorldofWildlife]

Hello! I was wondering if and when my female Xenesthis immanis will reach her adult colors of black and pink? I have had her since October 15, 2021 and now she is pretty large. I would say 5-6 inches across leg span. It’s November 2024 now and she has molted five times since then. The last being in March of 2024. I am expecting her to molt again by at least March 2025, but I would like to understand if it is common to not reach adult colors till later? Has she just not reached adulthood yet? Her last molt revealed, from what others have told me, a mature female.
Her colors are still the same since I had her. A slight darkening occurred from the last molt, but she lightened up since then. Perhaps this next molt will reveal a change?

Just a side note: I bought her advertised as a male, but that changed after these past years and molts revealed otherwise.

She cant look like Xenethis imminas becuase she is not a Xenesthis.
Clearly visible at leg IV.

That's not even a Xenesthis. I'm pretty sure it's a Pamphobeteus.

The spermatheca does look like it could be Pamphobeteus

I'd be reaching out to the seller in an attempt to get an ID. It could've been an honest mistake...the small slings look similar...but I feel like there is potential that they might immediately recall the situation and know the species. Even though it's been 3 years.

Then there's worst case scenario...the long con maybe that seller doesn't exist anymore. Cut your losses and just don't breed it.

What a dumper

That abdo is huge! Its amazing. Its a shame its not what you wanted but maybe its even better.

 

[WorldofWildlife]

Wow, that is a surprise! How can you tell that it is a Pamphobeteus? I purchased her from a Garden Store, which sells pets/supplies as well. So, the seller is unknown. Not only did they get the gender wrong, but the species as well!

What is it about leg IV that says it is not a Xenesthis? Is there any way to tell what species it really is?

How can you tell?

How can you tell?

By the markings at the front of the carapace. It's like the markings of a Pamphobeteus.

And what was mentioned above, a Xenesthis species would have a thickened scopula

How can you tell?

Not sure if this helps but im trying to vulgarize it




spermathecae does look similar. But who am to challenge the experts

You've done a great job keeping Her Healthy all this time.
Mystery Girl looks well fed with nice chocolate coloration.
Pretty Nice Look'n Tarantula.

Thanks, I still love her very much!

Here is a better photo of her:

this is a gorgeous healthy tarantula. No matter what it is.

It’s because they’re both advertised / casually named as Purple Blooms. it means the two species get confused. Pamphobetus Sp Machalla and Xenesthis Sp Intermedia.

2. Picture:
Absence of scopula on Metatarsus IV (see picture for comparison below) distinguish this specimen from Xenesthis spp.

1. Picture:
Presence of an pad of plumose setae on Femur IV and shape of spermathecae (two receptacles, basal fused !?) fits to Pamphobeteus spp.
The basal fusion of the receptacles is more an educated guess because this part is covered by the unterus and is not visible.

3. Picture:
The typical "eye mask" fits also to Pamphobeteus spp. But be carfull, it´s not present in every specimen.

Interesting! Thanks for sharing. Is it possible to determine exact species? She did have pink femurs and peach pink carapace (there is a noticeable color difference), but these faded since the last molt. Here are some more photos:

Is it possible to determine exact species?

The answer is simply no.
The reason is, there are so many unidentified and undefined Pamphobeteus in the hobby, without any data of geographical origin but often highly similar.

My guess, only based on the last 3 pictures, it is an Pamphobeteus sp. from SW Ecuador. Something like sp. MACHALA, sp. S-ECUADOR, sp. ECUADOR II and so on.

Ok, thank you for educating me on such a beautiful group of tarantula. I was leaning towards P. machala, since the growth and patterning/colors seem more consistent with that species, but like you said it’s almost impossible to tell. I will hopefully be able to contact the breeder soon, so maybe I’ll be able to find out then. Thanks again for all your help!

I got great news! She is confirmed to be a Pamphobeteus machala. I was able to contact the store and they relayed to me the breeder information on this specimen. The T was simply mislabeled on the store shelf, but not on the paperwork.

Awesome spider with a brand new identity, congrats

 

[Stu Macher]

That's a Pampho and a beautiful one

Great news. I was at a show recently and I went from one vendor to another and saw Purple Blooms for sale. But mainly the two your Tarantula was mislabelled with. .
