Mystery tarantula

It wasn't the species it was sold as and the dealer is also confused as to what it is.

1.25" and is already a mature female
Does the dealer have a list of possibilities? Multiple choice questions are soo much easier lol.

Unfortunately not. Seems like the mix up happened with the supplier. A species that has females mature out at 1.25" wasn't on their order list.
 
Theraphosinae without urticating setae type I.
Most likely Thrixopelma sp.
Note that Volker also took a look at the spermathecae and also suggested it looked like something from Thrixopelma. Unfortunately, he nor I don't know of Thrixopelma species that would mature out at 1.25"
 
No idea what these measurement means and how do you define "...mature out...".
But Thrixopelma could have well developed spermathecae around a carapace length of 10 mm. At these size they wasnt "full grown" but produced offspring after the next moult.

The process of identification really is just a multiple choice question, but with a lot of possible answers you generate yourself including "none of the above." What I do with my own IDs is to first identify the subfamily, produce a list of all genera in the subfamily, then start crossing off those that are obviously not it. Afterwards, I have a list of fewer, but still a lot, of possible matches. Then I start looking at taxonomy papers for the remaining genera in the list and compare the descriptions to what I see in my microscope and start crossing off more from the list until I have even fewer possibilities. Once the tarantula is identified to genus, I start the whole process over again for the species within the genus. To get accurate results, you have to assume the scientific name on the price list of every dealer is wrong and approach an identification without bias.

Simple enough, right? o_O
