 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?

 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.
