the eye is hairy and the reclinate orbital is rather strong, so I am thinking Phorinia.

According to Tachi and Shima (2006),
Phorinia "is characterised by the following combination of characters in the tribe Exoristini: facial ridge with strong setae; occiput without rows of black setae behind postocular setae; R4+5 setulose dorsally from base nearly to crossvein r-m; apical scutellar setae erect."

It is collected as a pupal parasite of Perina nuda (Erebidae: Lymantriinae)

@ John: you are totally correct, so it is one of the hairy-eyed Exorista species.
Based on the photos and the host, it is very likely / almost certainly Exorista sorbillans.
