Weird coloration after molting of Grammostola pulchra

[Dorifto]

The hairs are yet black after a molt, the exoskeleton may have a greyish tint while it's soft but they don't show brown legs and grey carapace, that's weird.

Here are the her new pictures from above:





And a picture of her from last month:



I really don't know why she changed her colour in brown I'm worried about her

You have the first grammostola bohemei

Can I send these pics to a friend?

Are you sure? I hope not

I was joking

Of course. Her body length is 4 cm if it's helpful for you. I really hope that she is a pure Grammostola pulchra She really was expensive as I bought her.

Ask to the seller where they sourced the T

I don't think you have to worry about her, but this is indeed a really weird colouration. May I ask from whom did you get it?

So, here's the answer I got:
Unfortunately, the pics arent good but it is more likely to be G. quirogai than "hobby pulchra", if you can, ask the person for closer dorsal pics and, if possible, without flash. For now, I go with G. quirogai, but I cant be 100% sure about it."

This guy works with Grammostola practically 24/7 so, he knows his stuff.

Yeah, as I stated above it could be a Quirogai.
There is one reddit thread about the same problem.

The "pulchra" turned from black to bronce colour, like yours did.

So if both G. pulchra and G. quirogai can turn brown before or after a molt, and are morphologically the same except in a male's tibial spur, how can anyone trust an ID based on a picture?

I have these doubts too, but I used to compare this cases to people who know how to distinguish south american coral snakes and false coral snakes, there are some slightly differences that only the ones who work with them 24/7 are able to differentiate, I believe its the same case here (and others too), however, even the guy that knows a lot about pulchra and quirogai had the careful to not state it.

Thank you all for your many replies! The pictures I've taken were without flash but with a lamp for better lighting. Could it be that my tarantula is a hybrid between Grammostola quirogai and Grammostola 'pulchra'? Her hind legs are brown and her front legs black, - it looks like a mutation
Is a quirogai - besides of her brown colour, any different in keeping than pulchra?

Yes

You need to feed the with brown crickets instead of black ones

I have read that Quirogais ta tibial hairs are brownish while the Pulchras are greyish. The Pulchras can turn into a brownish color just before a molt, not soon of just after a molt.

Quirogai:


My pulchra the two days before molting turned brownish, but like a faded blak.



Next molting, one month before last molt, one year and a half ago...




Each molt side by side

Thank you! Is the Grammostola quirogai the same size of pulchra, or smaller?

 

[Dorifto]

I have no idea, but being so similar, almost indistingishable they would be about the same size.

Both are increible Ts, I don't mind if mine suddenly changes the collor to bronze, it looks gorgeous.

Hello folks, I got new pictures of my Grammostola pulchras/quirogai today, while I was changing her setup:
