Apparently the most complete overall reference on Trirhabda to's often repeatedly cited in later publications referring to the genus.

Hard to access in libraries, but can be ordered from UMI/ProQuest (for "UMI Publication Number", use "7027230").

for UMI refers back to BugGuide.

Thanks for catching that, Brad
I fixed the link (seems I forgot to insert the URL when I initially posted).

PS: I haven't had the opportunity to view this work. So let me know what you think if you happen to purchase it. I'm very interested... seems well-respected in later publications that cite it.
