A familiar-looking fly, attracted by the light, was photographed on my balcony.

2.5 mm head-abdomen; Minas de Riotinto, Friday the 13th.

Although familiar-looking, I can't find it. :|


¡Saludos!

Thanks, John!

Yes, it looks like an elongated Drosophila! ;)

Most of the genera of Drosophilinae are modified Drosophila. Millions of years ago a Drosophila landed in Hawaii, lost some weight, and returned to the mainland as a slim Scaptomyza. By modern taxonomic guidelines Scaptomyza should be merely a subgenus of Drosophila or all the subgenera of Drosophila should be promoted to full genera.

The characters visible in the picture are by no means convincing, rather contradictory (acrostichals, humerals), but I still think it could be S. adusta. Are there better pictures of arista, genitalia...? Or even this specimen has been kept?
