    Advice given to me recently was.....
    "Usually, the females book lung spacing is closer together (top left is close to bottom left and top right is closer to bottom right) but there is a wider space between the bottom two book lungs.
    Males are the opposite. The top left and bottom left have more space between them and so on for the top right & bottom right. The bottom set of book lungs tend to be "closer" together"
    Based on this principle, Male on top and female on the bottom (so missionary style. ....lol)

    Lol. I'll be happy if at least one of my juveniles turn out to be female!

    Your GBB is DEFINITELY female. Difficult to say about the top specimen. In younger/smaller T's, a dot in the middle of the exuvium doesn't always indicate male. Sometimes, it's the beginning of the opening of the uterus externus (females "lips"). Hope this helps!

    Yup. You can see the epiandrial arch forming.
