Hi Don, drowned so a bit of decomposition has happened. I thought it was worth a go as it floated past, just in case.

As far as I can see the main differentiation in these species is the shape and number of spots in antemedial (AM) area. Also presence/absence of a dot or vertical line in large medial (M) patch.
G. saginaea - 2 AM spots; dot in large M spot, M spot tapers away approaching inner margin
G. sp. USNM5 - 2 AM spots, different shapes to above; dot in large M spot, M spot less tapered
G. prionsticha - 3 or 4 AM spots; M spot on costa, rest of band mostly dark with indistinct small spots
G. flavia - 3 AM spots, large on margins, small one between; 2 M spots
So above moth conforms with G. flavia
I am unsure what genus to use on NM Ian? Gymnasura or Asura ??

Gymnasura flavia
