Sorry about the last pic I didn't realise it was small. This is the only other pic I can get my phone is BAD and I don't own a camera.
Couldn't find an obvious flap on my N.Tripepii but this is my first time sexing a moult so second opinions would be nice
@SuetheBlue No reason to give up, it just takes practice! Here is a cropped image that may help see what @KezyGLA and I noticed: https://i.imgur.com/bAGmZKk.jpg. See the little structure that looks like a slug's face? It's translucent because this is a juvenile/subadult female. It will darken as the spider matures.
@dangerforceidle Ahh yes I see it. Thanks. I did sex my female geniculata and rosea correctly but they are both mature adults and the spermathecae much clearer. Am waiting for my juv albiceps to molt then I'll be coming to you guys
Thanks @dangerforceidle xx the T's just hit around 10/10.5 cm, I'm still getting a mix of answers from other places so I've decided to just wait for another moult just to be safe I do hope it's female though I'm fond of this one in particular she's my biggest T, rest are small juvs or slings x
