Melanura/Synspilum vent shot- Male?

[Cohazard]

Can anybody positively ID sex based on this vent shot?

I believe I have a male here.

Any chance of us possibly getting a close up shot? It looks to be male to me but I could very easily be wrong. A close up pic would definitely help us help you out easier.
