Yes, either crassipennis or oblonga.

central stripe of abdomen is rather small, I can also provide photos of the sternum, which is clearly narrower than the ventral membrane, so it should be a ♂
E. oblonga.

I hope this shot is convincing

Genitalia are out of focus, are you sure it is a male ?
In any case, male oblonga is much redder and much more elongated, so that it is not. Check the gallery.

Looks very male to me.
here two dorsal shots
What about
E. leucoptera - would this be an option?

Yes, a male it is.
For me, this is well within the variability of crassipennis. It is definitely not leucoptera and as said before, I don’t believe it to be oblonga either.

So, the sternite width mentioned by Tschorsnig should be considered as irrelevant?
Dorsal stripe resembles this observation, IDed as
oblonga:

Certainly darker red, but isn't coloration quite a variable character, which might even change over time?
Abdominal shape favors
E. crassipes...
