Phyllonorycter sp.? - Phyllonorycter emberizaepenella

Phyllonorycter sp.? - Phyllonorycter emberizaepenella
Groton, Middlesex County, Massachusetts, USA

Moved from Phyllonorycter mariaeella.

Based on recent discussions with Terry, P. emberizaepenella differs from mariaeella in having a white medial basal streak and in having a partially white head tuft. Here is an example confirmed by dissection/DNA:

I believe the basal streak and the black marking that Jim mentions both exclude P. tritaenianella, and that everything that had been filed under that species is in fact P. emberizaepenella, with the exception of this one

which is identical to my own reared specimens of P. tritaenianella (from upper-surface mines on Ostrya, rather than from underside mines on Caprifoliaceae as in the other two species).

Thanks Terry.

Phyllonorycter mariaeella
We have only a couple of three-bander Phyllonorycter spp. (tritaenianella and mariaeella) in the eastern USA, and of the two, this is P. mariaeella.

 
Phyllonorycter sp.
There are confusing mixed signals in current MPG, BG, BOLD, Microlep images among at least P. emberizaepenella, tritaenianella, and mariaeella sp. Though your comment here in 2011 indicates 2 sp. of Eastern USA 3-banders, it seems there may be at least a third perhaps recently newly identified - namely emberizaepenella. You had identified and passed through Bob Patterson in 2007 this BG image from Wisconsin as tritaenianella. It shows a dark blotch on the band closest to wingtip, which seems never to be indicated in any of the BOLD or Microlep images for tritaenianella (example from BG from Ontario for tritaenianella more like dark blotch-lacking BOLD images . Could the Wisconsin image rather more likely be one of the other two, which both show the dark blotch feature in BOLD? Possibly your initial ID for the Wisconsin image set up a cascade of other images (another example - from Massachusetts - with the dark blotch being assigned in BG and MPG to tritaenianella. (Also a quite similar image from the same collector in same area of Massachusetts shows up in MPG and BG as mariaella . The spread images in MPG for tritaenianella and some images in BG for tritaenianella are more like BOLD with their lack of the dark patch. I just submitted an image from Pennsylvania under Phyllonorycter which I believe due to its dark patch is either more possibly emberizaepenella or mariaeella, but not as likely tritaenianella. But I understand I think the perils of trying to ID any of these things from images alone and perhaps your thoughts have changed too since at least 2007-2011?
