      @s0n1cs3v3n It looks like it just molted. Were you able to get the exuviae?

      It must've sucked the moisture out of the molt right after molting... it was all munched up :(

      @s0n1cs3v3n The abdomens are often bunched up, but it may very well still be usable. Tips for getting a good image for molt sexing:
      1. Cut the abdomen off of the rest of the molt
      2. Cut off the bottom of the abdomen below the second pair of book lungs. (This is especially helpful for small exuviae. Otherwise, it has a tendency to fold in on itself.)
      3. If the molt is too dry to unfold, prepare a dish of water with a drop of dish soap to reduce surface tension. (Otherwise, the light molt floats on top without absorbing much moisture.)
      4. Place the molt in the dish. Let it soak for up to five minutes (until it becomes pliable).
      5. After removing the molt from the water and positioning it for photographing, let it dry for a few minutes. (When the molt is wet, reflections on the water can obscure critical details.)
      6. Photograph the inside of the abdomen, focusing on the area between the first pair of book lungs. Sometimes it helps to backlight the molt.

      @Ungoliant thank you, I've only ever done step 4 with no luck in being able to identify the sex. I'll try doing it that way. :)

      @s0n1cs3v3n Make sure you have the right part too. If the abdomen is in two parts, the one attached to the carapace isn't it.
