thanks for posting that. i have a 6" T. blondi approaching a molt and ive never sexed from a molt before. that will definately help me out. funny everytime something comes up, i sign on here, find a post and my question is answered. if not i ask and get several replies. these boards are a Godsend.
Remember that this device (the spermatheca) will look different from species to species. Some will look like a large flap, others may be just two separate little loops on each corner of the epigastric furrow.
Since this was a fresh molt, it was still nice and juicy. Totally pliable.
