May be ...Prosthiochaeta flavihirta(ハマダラヒロクチバエ)???? Platystomatidae.
Prosthiochaeta flavihirta gives only 1 hit at Google! And there are no images on the net. Is this a rare species? Or does it have a different name?
This is a very spectacular fly, relatively large and very pretty, I am surprised to see no images on the net!
This one is which the new species publication was carried out in 1987. However, since I also see well, I think that it is not a rare species.
This one is seen on dung & woods Syrup.

なんか怪しい文ですがだなあ・・要するに1987年に記載された種です。ワシも良く見るので珍しい種類ではないと思います・・・ということです。
