Hmm, the ventrals actually look kind of similar to me, at least in overall pattern. I was trying to figure it out by epigynum from Dondale & Redner 1978 and dismissed P. dispar because I couldn't match what I was seeing with the diagram on page 62. I couldn't find anything else that looked good either. The shape of the epigynum in yours looks very similar to mine though, and when I look at the diagrams again, I think I can see a match with P. dispar. I still don't know what I'm doing on that front though, so I'll eagerly await rescue by Rod. :)

Yes, I'd say dispar although the coloration is atypical. Maybe females get to look like this if they live to a great age. This one would definitely have to be "long in the tooth" since they mature in April or early May.

Interesting, I'll keep my eye out for others that look like this.

Is it safe for me to move these to the species page?

Go for it.
