2.5" Female Psalmopoeus irminia [molt sexing]
When this spider molted in January, I examined its exuviae and didn't see any signs that it was female. But lest mine eyes deceive me, those are spermathecae.
I'm fairly certain that I see the "flap" on the right picture which would make it a female. Hard to tell if it's a flap for sure though based on these pics.
 
Looks very female to me. I noticed when mine were a bit smaller (probably 3”). the spermathica were basically completely hidden behind the uterus which at first made me believe male, but the next molt i was able to correctly Identify. It may have just been my inexperience (was pretty early on in my keeping) but i remember that the actual spermatheca were very well hidden. LOL
 
I know it's been a while but I can't help but answering.
The fact that it has spermatheca makes it pretty much 1000% certain it's a female, jeees. Someone even wrote "I also see a flap between the spermathecae.".
