Hi everyone,

This drosophilidae was found in a composter (north of France) :

Altitude : 36 m - Taille : 2,5 mm
Réf. : 343561

Unable to discriminate the head micro-setae with my gear, the question is : does S.flava is the only one to present such a truncate oviscapt ?

I would rather consider Lordiphosa andalusiaca, Is it possible to get less granulated picture?

Here it is, without any accentuation :

S, flava has indeed truncate oviscapt. In this specimen it is more oblong, although it is not well discernible in the picture. Also, mesonotum is more glossy, etc. I stay at L. andalusiaca.

Thanks.
Maybe another opinion to confirm?

I agree completely with Jan. Tip of ovipositor is rounded in lateral view, not truncate. The darkish smudges on the pleura also indicate Lordiphosa.
