Thanks! Based on that family name I was able to find examples within Typhlophis which are comparable and in this part if Brasil.
The small white marking on the costa of the forewing makes me think Hamadryas amphinome but the whiteness of the larger "stripe" leads me to think Hamadryas arinome.
Definitely Isognathus. Looks very much like Isognathus aposematic and leachi, but without the long false antennae on the posterior.
