Sexing with this picture would be impossible. It might be possible to sex the molt with a good microscope focused on the right area inside the molt, but I'm thinking the molt might still be too small to tell
I've been able to sex moults at <1" with my cheap Amazon microscope/endoscope... I've done three so far, my Euathlus condorito, my Lasiodora parahybana and my Brachypelma auratum.
It's possible, but the trick is that they have to be perfect when you pull them. The minute you wet them down, it becomes impossible to see.
