I just want to ask some opinions... I bought this T as a G pulchripes as a sling. This is the first one of this kind I bought so I don't know what they are supposed to look like(during the immature phases). Now I am starting to doubt whether it really is G pulchripes because of pics I saw of specimens about the same size. When is the golden markings supposed to start showing? This one is about 4-4.5cm.

Can anybody with experience with G pulchripes please tell me if this is what they are supposed to look like?

Sorry the pictures aren't all that clear,I'll try to post some better ones. It's a bit more of a blue-greyish clour than it looks in the pic.

and a more ventral shot

I am by no means an expert, but I do own 2 G pulchripes slings, they don't look like this and they are probably 1 molt behind.
This does however remind me of my Aphonopelma seemanni which is known for it's orangey underside.
The markings on the knees are also indicative of this.
Please keep in mind that there are many Ts that have the same white stripes on their knees which cause confusion.

But this looks a lot like my A seemanni.

Here is a pic for reference. Was 5.5cm in this picture (When I got her).

Orange spinerettes are a trademark of the A seemanni species.

Here is my 3.5cm Grammostola pulchripes for reference.

See what you mean, think might be right!!

Does it burrow much?
Both my G pulchripes and A seemanni burrow, but the A seemanni almost never comes out, while the chaco cruises around out in the open most of the time. In premolt it will stay buried for weeks though.
