Hello, I photographed this fly in the Girgini forest, Sardinia (NU), Italy, 900m a.s.l. on May 15th 2025. I think it is a Rhagio, but is it possible to identify its species based on these photos? Thank you in advance, Emanuele ESant attached the following image:  [293.78Kb] |

Female R. scolopaceus (if there's not a very resembling in Girgini forest)

Thanks again! I think the only other alternative would be R. sardous, but I'm not sure if the color of the legs and abdomen is more consistent with that or R. scolopaceus. In any case, I collected the specimen, so if additional photos are needed I can provide them.

I've read through "Review of the scolopaceus-group of Rhagio" by Zeegers & Álvarez Fidalgo and found: "Diagnosis: As pointed out by SZILÁDY (1934), this species resembles R. maculipennis, but can easily be separated by the yellow and elongated third antennal segment..." So if you can post a detail of the head we may be sure wether it's sardous or not. Greetings, Eric |

Hi Emanuele, I've studied the key and as all femora are dark and the abdomen is dark, too, with "reddish margins": your fly seems to be the endemic Rhagio sardous and I'm curious if Theo agrees
