Acanthoscurria geniculata ~2.5 DLS

I tried to sex this spider’s molt, and I could not find any evidence of a spermatheca at all. However I saw the little white setae on the furrow and I am wondering if this could be indicative of a female? What are your thoughts??
At this size with magnification, you should be able to see evidence of spermathecae when you examine a molt. I'd go with the conclusion you reached after looking at a molt....ventral sexing is not 100% accurate. If you have doubts, then look closely at the next molt to confirm it.

Thanks! The molt was pretty shredded and this one’s my favorite so I was hoping for a gal! Thank you! 🙂
 
I confirmed this spider as female with her latest molt. I just wanted to give an update for future references.
