Arctidae? from Madagascar

Hello everyone

I need help with identification, a friend of mine was last year in Madagascar and has sent me this photo of these Arctidae ??? I collect there, if someone can help in their identification, I thank you very much.

Thank you all
Jose

Dear Andreas

First of all, thank you very much for the help.
Yes, it seems to be this species, although yesterday my friend sent me the size of the extended wings is 69 mm and 72 mm wingspan, they seem to be two females, he tells me that one of them laid eggs and the caterpillars hatched but they did not accept any plant, finally, they only accepted a little bit of Schinus molle until the beginning of the second stage but they died.
Thank you so much for everything.

Best regards
Jose
