Few specimens, by shaking branches of evergreen Quercus, altitude about 650 m. In total I have encountered it in 4 places of southern and SE Greece, from June to September, at altitude 0-1300 m., in various plants (Pistacia, evergreen and deciduous Quercus, Abies). Length 2.6 mm.

Hello George, has the separation between Amauronia and Pseudoamauronia a solid base?  G.

Hello Gabriele !!! Difficult question and unfortunately I do not have access to K. Majer's article to answer with some seriousness [Majer K., 1997: A revision of the tribe Amauronioidini (Coleoptera, Dasytidae). - Acta Musei Moraviae, Scientiae Naturales 81 (1–2): 363–402]. So, personal point of view: Yes, I believe that these are 2 different genera, which are easily distinguished from each other. - Winged insects, with parallel to each other the sides of the elytrae and clear presence of shoulders. Pronotum shape that strongly resembles the genus Danacaea .............................................Pseudamauronia Pic, 1915 - Wingless insects, with curved sides of the elytrae and barely distinct shoulders. Different shape of pronotum ............................................. Amauronia Westwood, 1839 (= Aphyctus Jacquelin du Val, 1860). M. Pic also mentions small differences in the shape of the eyes and the claws, between the 2 genera. But comparing my specimens, I find them insignificant. George |

OK, I had the article of K. Majer (by G. L.   ).Also Majer considers that Amauronia and Pseudamauronia are 2 different genera. At the end of his work, there is a cladogram based on 38 characters, which seems to fully confirm this possibility. G. |

I see, I have some to determine myself, I will try with the paper. I am becoming more and more skeptical about this "traditional" approach. The criterion was to put all winged species in one genus and all wingless ones in another one -- but how can we be sure that loss of wings was a single event for all of them? G.
