Thanks for reaching out about Bob Luigi and including a photo. Males typically have two differences than females, but sometimes difficult to determine. Males tend to have very long front nails. Males also have longer, more narrow tails, where the females have shorter tails and the cloaca is at the edge of the shell. Good luck.
