I guess that this is Ptilostomis, according to the web-pages. But what is the species name (ocellifera??)?

Certainly looks like Ptilostomis, but I'm not sure I know how to distinguish the species. Wait for Dave on that score.

While the photo is not as good as the previous (the wing venation/coloration is not in focus) I don't believe it is ocellifera as as my specimens of ocellifera are generally paler and with less wing coloration than the other two likely species (postica and semifasciata). I would not feel comfortable using just size and color to separate these species. I think you need to take a good look at the private parts to be sure.

There is an excellent source for this family:

Ethan Bright's website gives keys for Ptilostomis to the species level (based on the Wiggins reference that Creno mentions):
