Senegal, Sali, very common on vegetation in hotel garden. The same I've seen in Thailand. So, it has to be something very common at all. May be somebody knows?

glad I was right about subfamily.
yes, I agree. awesome fly. Indeed, among the most beautiful flies are Rhiininae (in Calliphoridae) and Miltogramminae (in Sarcophagidae) and there are some green Chloropidae that are awesome!
