Taken in the mountains of Madrid on the 21rst May 2011. Parageron? Geron? Doesn't seem to fit anything that I know  Help, please! Thanks in advance!

part of the "Usia" aurata group, difficult to name without dissection but in this case i can fairly confidently (99%) call this one Parageron loewi (Becker, 1906). i think it is currently placed in Usia but IMO your intuition that this is a Parageron is correct. |

Thanks so much, David!!!  I guess this means the best way to name it is Parageron cf. loewi  Please, what make you think it is loewi instead of aurata? |

Piluca_Alvarez wrote: Please, what make you think it is loewi instead of aurata? I have seen no specimens of aurata ss from Spain. There are, however, two similar undescribed species that occur in south Spain, but these are rare and, although specimens are few, i have never seen one of these that looks like your specimen. Apart from genitalia, they differ in male eye separation, hairs on frons and nature of dusting on mesonotum, some of which features are visible in your photo. |

This is Parageron loewi beyond any reasonable doubt. |

Well, David, I have read your post again and it was ME, that didn't understand correctly. Your explanation was clear enough. It is updated now, and I am happy that you are so confident of your ID (considering it is from a picture). I am most grateful for your help and patience PD: In the Taxonomic lists used in my site it is placed in Usia. I change the genus then for coherency.
