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) ValerioW attached the following image:  [74.55Kb] Edited by ValerioW on 14-07-2016 10:14 |

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). Stephane. |

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 Edited by ValerioW on 14-07-2016 20:49 |
