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.

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...
