Psalmopoeus pulcher male?

Got a microscope and have been messing around with some molts I had. So far it seems I’m getting males. I’d like confirmation so I’m sure what I’m seeing is correct and can apply it to the other ones I’m currently unfolding
I looked up spermatheca of Psalmopoeus pulcher and it did look like mine. The brown structures just looked like male accessory organs. If this one is suspected to be female, the Lasiodora parahybana I tried to sex likely is as well. It’s much less visible in the photo but looking through the microscope I saw it. Do females also have those brown structures? I’m not the best with tarantula anatomy, to be honest. But if they were male, there would just be nothing in between, correct?
I was curious about the two brown structures as well. I was thinking male accessory organs, but the spermathecae is present. Correct re nothing in between if male. The uterus externus and/or spermathecae are what I look for if female. As you’re using a powerful microscope, I think you’re able to see more than what I could have haha. Awesome shot nonetheless. If you’re feeling uncertain, label the specimen suspect female and confirm with a future molt. Please tag me when you upload it. Also, nice job unraveling the exuviae. I know how hard it can be ;)

It was difficult, but worth it as I was very curious to see if I could have a guess made up by the end of it. I have them saved in my phone and labeled with the size and species, I was counting on sexing every molt until I’m positive to find out how early on I can be accurate with it. It is interesting, nonetheless. I’ll be sure to tag you next molt on this one as “she” went from 1-2” this molt. Should easily be able to tell with the next one.
