Nope. Take care on wing veins pattern, it does not fit.

Sorry but it is not
Hebecnema. The adbomen with large dark triangular spots sounds more like
Spilogona spec. The altitude too.

I read your tip and while trying to get a clue about it, I read again
H. vespertina description and it convinces me that it could be this one. I don't even see those triangles you mentioned.
Rozkosny says:
1- about
Hebecnema sp. males "[...] abdomen has no paired spots"
2- and about
H. vespertina "wings moderately brownish" and for males " [...] abdomen with a short black midline (often absent in T4)"
From the picture it appears like that (the red area starts on the right, with T4, with no black midline, and continues to the left with the black midline visible)

The black trapezoidal spots are those on both sides of the midline you highlighted.
The distance between both last dc let us suppose it has only 3 post dc, so not
Hebecnema. The frons is also too broad for a male
Hebecnema, and the parafacials are well too wide (even visble from above). I'm confident that it is not
Hebecnema.
I hold to my first thought about a
Spilogona species with dark infuscated wings (like
S. dispar for example).

Ok, dc are few, you are right!
BTW: I think you're confusing fronto-orbital plane with parafacial. The latter is not visible from this upper view, and is in the lower side of the head
