I would say Dettopsomyia sp., but without any more profound study. I have no experience with this genus.

Thanks Jan for pointing me right direction with your excellent comments. I look up at the paper by Okada (1982):

my fly seems to have a closer resemblance to Styloptera.
Once again, thank you for your useful information.
