Liberifer does not have worming in the face.
Male liberifer tend to have black freckles on the face and body while females do not. However, I’ve had males in the past with no freckles, and I had one big dominant female with freckles who I was sure was a male until she laid eggs. So while it’s a pretty good determiner of sex, it’s not 100%.
IMO it’s a little too young to know for sure.
