Dorsal side of dissected and partially cleared epigynum (used clove oil). You can see some parts of the atrium on the left side where the tissue was super thin and then it just kind of cracked apart when I tried to move it around, oops (after moving and poking it so much, it just wore out).

I asked Allen Brady to check my ID on this one because the spermathecae (the red parts) looked slightly different on mine than in his Tigrosa revision diagrams, but he confirmed that this is, without a doubt, a Tigrosa annexa. I'm posting one more picture of the spermathecae after this one, just to show the little "horns" better from kind of a side view of the epigynum.
