 Hi everyone,

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

www.galerie-insecte.org/galerie/image/dos343/big/P1420583%20873%2025%20mm%20corps%2028%20mai%20lauxaniinae%20sapromyzospma.jpg

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.

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