What sex is my B. Smithi?

[Jens Rasmusen]

So a few days ago i sexed my female A. Versicolor (8,5 cm molt) . She had that M shaped spermato flap that makes it pretty clear that it is a female

The flap on this B. Smithi (10,4 cm molt) is there but it is not M shaped.

Idk why the pictures are where they are, but they went flying for some reason

My thought would be female. But, I'm no expert, I'm always having people doublecheck me..

Yes it is female. Spermathecae come in all sorts of shapes and sizes or can be missing altogether depending on the species. Brachypelma have fused spermathecae and so look like this-

C. versicolor have paired spermathecae and look like this-

It's worth having a look at the link to the sexing guide that was posted earlier.

Also, as a side note, if you pull the uterus externus down and look at the spermathecae and it is wrinkled like the one I posted above then it is B. smithi but if it is smooth and looks like this then you have a B hamorii -
