you can't tell from that photo. Wait until the next molt, it is pretty obvious that way. People take close ups, and in reality if you can't see it, it's a dude. See below, full molt in view, Spermatheca is obvious
you are welcome. If you can get a cleaner pic, (focused on the furrow and book lungs) some people can give you an educated guess. But if you get the next molt you can verify 100%. You see the spermatheca in the pic I provided yes?
