Hi. According to the identification key from Tschorsnig (p. 70/71), this Cylindromyia species should be Cylindromyia intermedia because it has crossed apical bristles, and a posterior supra-alar bristle is present. However it appears to have discal bristles on the abdomen, which shouldn't be present for intermedia. Any idea?

Found in western France, near the city of Le Mans.

The antenna is way too short (and dark) for intermedia. So this is male auriceps. You misjudged the thoracic bristles, apparently (“third” samis pctually second). Alos, the small hairs betweem sa and ia are clearly visible.
