I think the working hypothesis has been that the red mark on C. crocata doesn't go all the way to the end. The hypothesis holds up with this specimen, if by end we mean actually reaching the spinnerets. It comes very close to reaching the spinnerets though. I'm working through a number of specimens in the descripta group and may end up making sense of this.

These are very nice. It's not looking great for our theory. =] Thanks for posting all these!
