Alexandru, it will be because the photos always put me in crisis (plus yours are beautiful), but I can not determine the specimen. Sorry. I would have to see it under binocular to get some idea. Anyway it is very interesting. gian |

Hi there, in my opinion it's very likely a male of Agrilus cuprescens Bests |

Thank you guys a lot for your help   ... I hope next year I will be able to collect more specimens and to ID them properly. Meanwhile I will add here this picture with a lateral view of the beetle, maybe it will help |

Hi there, I just wrote "...most likely...". A couple of things: the median lobe, "aka" penis, slides through the parameres, as you know. Therefore, the "aedeagus" may look very different, following the sliding degree. Moreover, this specimen's pronotal shape and outline doesn't fit so well with that of A. cuprescens, that's just a preliminary choice. Just a starting step. In my opinion, there's an unsolved trouble involving A. cuprescens and A. calcicola, The latter synonimized with cuprescens. Well, a short series of Agrilus of this group from Peloponnese in my collection are very much resembling the specimen here depicted, and I've named it (lacking better solutions) as "Agrilus calcicola cfr." That's all folks, I stop here for the meanwhile. A. |

This is a good observation. Unfortunately I have not any specimen of A. calcicola to compare with. |

Hi Adrian, after poking around a little bit I've found that Schaefer, in his Faune de France (that was published in 1950, and not in 1949 as currently quoted), briefly named an "ab. obtusifera" referred to Agrilus aurichalceus Redt. from "Caucasus, Hungary, Greece, France" like this: Cotés du pronotum subrectilignes Best regards, Clickie |

Here I have an image from Agrilus cuprescens, collected from just some tens of kilometers from the location Alexandru collected his specimen. I have serious doubts, of coexisting 2 subspecies in such a small geographic region. I don't have something to say about "aberrations". Needs a series of specimens. But in other regions where I collected A. cuprescens, I did not see "aberrations" with straight pronotum margins. Lot of old "aberrations" proved to be subspecies or even good species later. More specimens collected from the same area and the same host plant would make a better idea. I do not argue to what you mentioned above. I just want to clarify.

The specimen was ID-ed as Agrilus macroderus by Gianfranco Curletti
