Epigynum of adult female Wadotes. Initially I thought this was the species hybridus, but now I am not so sure. It appears the "scape" (downward directed spur-like process) has a shallow notch at the tip, which would suggest the species calcaratus. All opinions most welcome!

Could be hybridus
According to the drawings I have, the scape is more tapered in W. hybridus than in W. calcaratus, and sometimes there is a notch in either species. I think I see some tapering in this one, but I can't see the surrounding structures very well. Perhaps Rod can ID this one?

Judging by Dupérré and Paqu
Judging by Dupérré and Paquin (2003), this is W. hybridus (they show only the two for Quebec). The hybridus scape appears to be more tapered (although they suggest that there is some variation in this), but more important, in my opinion, the scape here extends beyond the posterior rim. This is clearly shown in their drawing of the epigyne for hybridus, whereas for calcaratus it stops short. The overall shape and extent of the shaded lateral regions posterior to the scape also makes for a much better match to W. hybridus.

Follow up --- looking at Benn
Follow up --- looking at Bennett (1987, available online from AAS), it seems clear, based on epigyne as well as location, that this is W. hybridus.

I agree with W. hybridus now as well.
