It looks like a well marked Renia fraternalis to me.

Is there a way to separate females? Forbes here says that female fraternalis and salusalis are indistinguishable.

If they cannot be separated, I'm thinking we should have a no taxon "fraternalis or salusalis" page. It would be little weird because there are not images currently under under salusalis and the only images under fraternalis are of females, so both species would be left empty.

I'm not really certain whether Forbes' observation regarding females is still accurate. I haven't followed the literature in years, so it might be or may not be. That said, the above specimen is most likely a male and seems to fit well, granted this entire group is often a difficult gradient in which to pinpoint various species by appearances.

What make this a male? The palps are different than many of those which have antennae with no tufts. Is that it? Sorry for all the pesky questions. If it's too time consuming, just say so.

The antennae are tucked too far under the FW to see the tufts, but the palpi are curved upward. In females, you'll notice the palpi are straight forward (porrect) and each typically bends outward making a little v at the terminal segments of the palpi. A good example of this is here:

There are a number of similar examples in BugGuide placed under Renia discoloralis. The source appears to be a tentative ID of an image here. Could you please take a look?

Here is a list of photo numbers that I suspect may be Renia fraternalis:

353702
359207
416845
418513
429177
488635

I was working on cleaning up the R. fraternalis page, as there were some photos of other Herminiines that were misidentified there, and while I was at it I moved these photos to the guide page. All look like good matches for R. fraternalis. What do you think about this photo? It's a bit farther north than I've ever seen the species, but I can't think of what else it could possibly be...

Now we need a guide page for this speciman and
