    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.

    That's a female. You can see the opening to her furrow. :)

    @Casey K: is that last pic an opening or a light reflex. I think I see a lightly pigmented epiandrous fusillae and a vertical arthordial membrane. How am I seeing this wrong. Thanks in advance!!

    That appears to be an opening.....perhaps mother picture without the flash would help. I see the dark coloration above the exuvium but it doesn't appear to be a triangular shape just yet if it is indeed e.f.

    Thanks @Casey K. I thought it would be wise to learn from the Master!

    Ahhh. I'm no master, lol. I make mistakes. I go off of book lung spacing, shape of furrow, exuvium, and some dorsal definition with certain species. I am pretty good with brachy's, though.

    B. smithi. I'll try for another photo. I never use flash, just a horrible phone photo.

    He had his mature molt and is definitely male. He's a G. pulchripes.
