ID French Guyana Lepidoptera

[jaguarae]

I have a problem with this species !
In fact at first , i thought it was an Ithominae like Oleria ...
Then i thought it could be an Dismorphia like theucharita ...

Now i don't know because nothing seems right

Is some one can help me for this lepidoptera from Saül (French Guyana ) in October
Thank you
