Thanks George.
I had not seen before in the Pond. But on my last visit to the wetland, I have seen and photographed several times.
Prepare and add more photos. It would be good, besides being an increasingly rare, the species could be identified.
Best regards.

It's probably O. leonina.
You can send specimens to me, along with Syrphids you caught.
You have my address ;)

It is not leonina as that one should have longitudinal stripes on the mesonotum. The combination of major parts of the head blackish, absence of longitudinal stripes on the mesonotum and yellow abdominal margin without large yellow spotst at the base and the tip of the abdomen lead me to believe it is not one of the species given in Rozkosny's European revision and possibly one of the species described later.

In my ignorance and lack of taxonomic knowledge, for the simple comparison of this image that already exists in the gallery identified as O. lion, I totally agree on the differences you point. Additionally, the color of the legs, not match.

For his drawings and well defined spots of white, I think this fly should be very characteristic. In the Gallery, I have not found. He knows if he can be described outside Europe.?

To try to help identification, upload two photos, which I believe are of the same species but of different individuals also photographed the same day in the wetland.

Best regards.

Same species but no name yet. I need to check the literature...

If you have the opportunity to collect males (plural) as well (eyes touching on froms), then please, do so. From what I have been able to see so far it may well be an undescribed species. I have 'located' four European species that were not included in Rozkosny's European revision: two species from the Canary Islands that look quite different and two species described more recently from Turkey. There is some resemblance with O. turcica but the yellow markings on the head of the female are different.

I will remember their wishes, within what my power .......

Males must have the eyes closer together ..?

I tried searching turcica Oxycera photos on the Web, but I have not found any.

Thank you for your interest in the subject. It is exciting to find something new.

Best Regards

With the sorry excuse that I never had seen a female yet, I have to admit with embarassment that this is the female of Vanoyia tenuicornis. Receiving a vial with three males of tenuicornis and five females of this 'Oxycera' from the same locality I got a bit uncomfortable and the key proved I was right to feel uncomfortable. Please add the female to the Gallyry, too. B)

I consider myself fortunate to have outstanding support from experts like you that without prior information may come to identify species with sexual dimorphism as pronounced as in this case.
And once known for its identification, identity as a female of that species, I also clarifies the curiosity that caused me, this insect commonly found in the company or at least in the vicinity, which from the outset you identified me as the male of Vanoyia tenuicornis.

Very grateful for your interest and help.
