Looks like Cylindromyia or could it be something else? Thanks! Picture taken in September, east China (Zhejiang province).

Antenna looks very interesting. Wing venation disagrees with Cylindromyia.
Could be another Phasiinae, but picture is unfortunately not sharp enough to see all the bristles.

Thank you for ruling out Cylindromyia. I took only two pictures. The other one is a lateral shot:

Yes, I think I see onky 2 post IA, so quite likely a Phasiinae.
It vaguely reminds me of Euthera.
It could be an Oriental genus.

Or it simply is a Lophosia, explaining the weird antenna..
maybe you can access this

There is a genus
Hermya from the region with long antennae, thin arista, discals on abdomen, weak or absent vibrissae, and often with darkened wings.

Thank you so much Theo and John Carr for the insightful guidance!|t I think it is probably a Hermya, Hermya beelzebul perhaps.

Hermya seems to ve a good suggestion, but beelzebul has wing very black as I remember it.
You don’t get rid of Sun though ;)he also described 2 Hermya from China.

Zeegers, thank you very much for ruling out Hermya beelzebul. I did a check and yes you're absolutely right. According to the key to three species of Hermya in China I found in a Chinse-language book, legs entirely black, then Hermya beelzebul（based on the second pic, hind femurs fulvous, so H.beelzebul ruled out）; femurs fulvous, or at least hind femurs fulvous, then either Hermya formosana or Hermya surstylis. Wings conspicuously bicolored with shining black spot on the upper area of the pareafacials, then Hermya formosana. Wings unicolored or inconspicuously bicolored without that shining black spot on the parafacials, then Hermya surstylis. So perhaps Hermya formosana?

Great work
Pity I don't read Chinese and I don't have any experience of my own in this genus.
I guess you are the expert now.
