need a help on determing the gender

[Alireza Zamani]

Hi All, I will be really thankful if you could help me on determining the gender of my moulted G. rosea and Avic:

[Peter Roach]

First photo is female
Second photo . . No idea as ventral sexing isnt 100% accurate (and photo isnt in focus anyway)

[Alireza Zamani]

Any Idea on this Avic avic?

Both spiders are female. Have a look here and you will see why.
