citharischius crawshayi Famale? male?

Hard to tell, but I wouldn't have it in a bag like that if I were you.

I think it's still too small to tell, but as a guess I would say female. Sexing the molt is the only way to tell for sure and you'll probably have to wait a for a few more molts to be sure
Btw, the genus and species name changed to Pelinobius muticus almost 4 years ago.
