Observed last month near a stream in east China (Zhejiang province), body length approx. 5mm. Judging from the general appearance and wing venation, is Gymnopternus sp. a good candidate? Thanks in advance!

Unfortunately, it is impossible to separate Chinese Gymnopternus from Hercostomus without microscope.
