Ephebopus cyanognathus, 0.75" DLS

I'm in love with this new microscope. I have a couple of my E. cyanognathus molts sitting around and wanted a reason to try it out, and I'm not disappointed!

Am I correct thinking those are spermethecae? I'm trying to discern which part would be uterus externus too, if it's there.
Another picture without the backlight here. I'm figuring out how to get a bit better clarity without backlight because it shows more detail, but I'm really enjoying this!!

Edit, I checked the other E. cyanognathus molt (same size as this one) and believe I'm seeing the same thing, just a little less developed and with (I think) a more visible uterus externus. Unfortunately I didn't think to get a picture before cleaning up... But really cool!!
 
This pic reminds me accessory organs and gonopore, I am wondering if they can "move" like spermathecae
At 0.75" I think they're more developed than accessory organs would be, which usually look like little dots at that small size. It's not out of the question, though.

Thank's for the explanation, didn't know that.
 
Where is the uterus?
No uterus, no female.
That is what I was struggling to find as well, but I'm not sure that I know what I'm looking for at this size haha. I've not looked at a molt this small before now 😅

I'm going to look through some other posts to compare what I'm seeing.

No, it´s not too young.
We have here good pictures which shows no uterus. But we can see clearly the small gonopore which is not fused with the these "spermathecae looking things" and these is typical for males.

A good read for this topic is:
Sainsbury, C. 2006. A little help with sexing. Journal of the British Tarantula Society, 22 (1): 11–15.


Here you can see a example at Tliltocatl klick

And this is a comparison ♀ / ♂ at Thrixopelma sp. (same size, same scale)
