Hello Andre,

This looks, at first glance, mightily interesting! In the above photo it looks like a member of the Illustrata-group. The eyes and facial knob are haired and the legs are partly pale. What strikes me the most is the broad face. There is only one species I know in this group with an exceptionally broad face: Cheilosia morio. A species where the larvae live in the resin of pine trees (unlike other cheilosia species where larvae live in and of plant and mushrooms)
The species has two forms (form A and sensu Bartsch et.al. 2009. The species will be split into two species. The specimen shown here belongs to C. morio form A, because the face is haired.

Greetings,

Ectemnius,

Your answers surpasses my wildest dreams.

As the species isn't split yet, I will name morio.

Thank you very much!!

Groetjes,
André

Hello Andre,

Now that I've examined the literature I see that the one with the haired face is in fact Cheilosia morio B. Another curious thing: the antennae in the depicted specimen are black. All females I've caught in The Netherlands and Belgium have bright red antennae.
Both Bartsch 2009 (whom describes the Scandinavian Syrphidae) and Pennards 2012 (who documents the first find of the species in the Netherlands) do not explicitly mention the species as occurring in the Iberian peninsula.
That makes this a very interesting find! Did you collect any specimens? Because this is so interesting that further investigation is warranted.

Greetings,

Ectemnius
