Acanthoscurria geniculata
What's the size in DLS? Always include the size of the specimen you're trying to have sexed, as it can be immensely helpful info to know.

I may be mistaken as I'm viewing this on mobile, but I do think I can see forming spermathecae.

If you take a pin and run it between the upper pair of booklungs, it should catch on a little "flap" you can wiggle back and forth. If there indeed is a flap, it's female.
