P. trienta and P. abydata both occur in Central Texas and most of us here are not real sure how to tell them apart. Can anyone here at BG give some advice as to what characters are helpful in distinguishing the two species.

Moved from ID Request.

Moving to genus for now.
These IDs are very difficult and I think that we need more information and instructions on how to separate all of this genus from Macaria, as well as each other member of this genus.
It's really beyond my capability, but I'm going to look into it and I have worked with Steve Nanz on a few of these already.

Thanks, Bob...
I've communicated with Ann H about this, and several folks at iNat, and I think I will only go to genus in the future.
