Perhaps Drosophila funebris.

Hello Paul, From internet I see this picture which is almost the same as this fly. It is said to be Drosophila simulans. http://www.lucasbrouwers.nl/blog/wp-content/uploads/2010/01/drosophila_rt_9c9_rs.jpg Is it possible...? Regards, Hedy |

The picture certainly cannot determine between D. simulans and D. melanogaster.

Great, then we may stick to Drosophila cf funebris... It is the first picture on the specieslist, nice. Thanks for your reaction!! Regards, Hedy Edited by hedy2411 on 14-10-2011 17:20 |

I don't think funebris. (not brown enough, black marks on tergites too triangular). But I really don't think Dmel or Dsim either (too 'square', blocky, triangular shading on tergites, and the dorsocentrals are too far back, plus the shaded cross-vein is wrong). I might guess immigrans (and the clouded cross-veins might support this) but there is not enough shading where the long veins meet the wing tips. Without a key to hand, I might guess D. histrio. Howver! This website clearly indicates that Paul knows Drosophila much better than I. Paul, can I ask what leeds you to funebris? and why not dismiss Dsim out of hand? Thanks |

D. funebris was my first thought. My reply about similans was more a reply in the sense that melanogaster and simulans cannot be separated based on the above image, so as an alternative both species are just as plausible. I have been looking at some other images of drosophilids earlier this week and I think your suggestion on immigrans is not half that bad. Unfortunately, the markings at the tips of the longitudinal veins are not discernable.

Paul. can you make clear to me with a sign in the picture or in a drawing what point you are looking for as I have some more pictures. Regards, Hedy |

I really think the colour and banding are wrong for D funebris (below) For D immigrans, the joints between the long wing veins and the costa (near the wing tip) are usually shaded. A good dorsal view with no reflection would show this. Ultimate proof of Dimm would be provided by a closeup view of the ventral surface of the forefemur which should have ~12 short conical 'peg-like' spikes/bristles/projections. The more I look though, the more I think the position of the dorsocentral bristles supports D. immigrans. (D. immigrans, below)  A dorsal view of the abdomen (without the wings in the way) would rule out Dmel or Dsim. |
