This dun seems to belong to one of those two genera. Does anybody know how to tell them apart? I can't find anything that doesn't require a male spinner.

Jason-

My belief is that Plauditus, Pseudocloeon, and Procloeon are the Baetids absent hind wings, whereas Centroptilum (among the others) has minute hind wings. If I am correct, then given the choice you posed, that would make your specimen Centroptilum. This is (of course) strictly based on my having successfully digested the "available literature", and as I remember, there was a bit of inconsistency between authors in that area, so I probably chose to believe whichever one (or ones) I believed to have more credibility. Does any of this sound familiar?
