Herminiinae mystery - Renia sobrialis - female

Herminiinae mystery - Renia sobrialis - Female
Pine Brook, Isanti County, Minnesota, USA
July 8, 2010
This gray mystery (for which I have only one image and no measurement or specimen) is making me wonder mostly about Tetanolita mynesalis or Renia sobrialis. Favoring Tetanolita (to my thinking) are the apparently saber-shaped and apparently not heavily fringed labial palps and the very gray coloration. Lacking, however (perhaps lost?) is the pyramidal scale tuft on the frons. I don't know what clues the foreleg might provide. Any help most appreciated.

Not Tetanolita IMHO
An unsullied reniform spot suggests to me a Tetanolita species. One or as is what appears to be the case here two dots in or around the reniform spot favors Renia. Hard to differentiate though.

Also hard for me at least to rear Herminiinae. Any advice?

 
Thanks for the advice.
Thanks for the advice. Checking again with Forbes (1954; the best technical guide I have at hand) I see there are characteristics in sobrialis ("palpus with second segment more curved and less tufted above than usual, third segment longer") I could be misreading (from a single, less than ideal, perspective) as the saber-shaped palps of Tetanolita. Also, the FW apex does seem squared and the outer margin quite rounded (I have a hard time assessing these geometric qualities--as in, compared with what? I guess they assume a certain level of knowledge and context). I'll wait for more consideration and maybe feedback.
I wish I had a good voucher specimen, or at least more and better photos. I've finally figured out the value of photographing my little collection for ID purposes and hope for some inroads on the Herminiinae that may also shed light.
I'm afraid I have no advice about rearing, though, having mostly forsaken it to concentrate more on just trying to learn what is here. I enjoyed it for a good while and cheer you on!!! (I still dabble, but very selectively).
Again, thank you!
