This is the area that you are looking at under the microscope (outlined in red, located between the top two book lungs). This is my red knee molt (since this molt was bigger it was eaiser to show you stuff then on my chaco molt, the same principles apply with both molts though).
In bigger females the flap can be seen with the naked eye (like on this one). In small females you cant see the flap (but you can still see the lady parts on the molt under the microscope.
The two antenna looking things (spermathecae) on my chaco molt seen under the microscope means it's female. Only the females have the antenna looking things (spermathecae). In males there will be no flap/spermathecae (so on the red knee, the flap outlined in red would not be there if this was a male, and under the microscope the antenna looking things (spermathecae) would not be there if it was male).
Hope this helps a little and i didn't confuse you. I wish I had a male molt to put beside it to show you for comparison but I don't have one. Any more questions just let me know!!! :D
