My N.chromatus molted only after a week long fast. Size before Molt was 10cm. Unfortunately the molt tore a bit when i opened it. I also can't for the life of me see the spermathecae.

Can you maybe get better quality picture.
And maybe a photo of the spider in question.

But from the photo's it looks to be a female.

focus on the circle to find the spermaticae and take the photo, also add some more light will help the camera focus.

I have tried taking photos again. Unfortunately this is the best quality I am going to get.










Here is the only photo I can get of her for now. Still very skittish after molt.




and here is one about 5 Months earlier. It is the best one I have of it before this molt.

Female , not too clear, but the shape of the epigastric furrow, being more of a "smile" than a tipical male straight line and the flap, in the second last photo of the spermatica, seems to show a shadow of what you're looking for.
