I'm not sure that this ID is right. I now think it might be Prays autocasis. See ALA for a single photo of this species but I can't figure out where it was taken. I've just uploaded another sighting of the same moth - see sighting 4643650. These two moths are very close in appearance and to me look different to Prays nephelomima.
OK I thought we were probably dealing with a single species initially, so I didn't look at the markings too closely while agreeing that the overll size and shape looked Ok for the genus. But now I see BOLD (Hobern) shows 6 named Prays species as set specimens. However I think the P. autocasis specimen shown there does not look like your 2 photos from life. Neverttheless I agree your 2 sightings look closest to the single photo of P. autocasis shown on the ALA especially when viewed from the side. I would be happy to classify both as P. autocasis if there is moderator agreement on this.
