Hmm.....On the last photo the prealar seems missing and i don't see the row of av/pv on t3 and we see 2 strong posterior setae on t1 So i have doubt about D. platura.... |

Good points, though I did think the pvs on t3 might be hidden from these angles. But I can't easily reconcile what I can see with any of the other candidates with a fore-tibial spur. Can we agree on 'Delia sp.'? |

I agree with you that the pv on t3 often are not visible on photos. And there are indeed not many other candidates with a fore tibial spur that could fit to this fly. The only candidate I could think of is D. antiqua For now Delia species seems right, but maybe Piluca has some more photos with a better view on the hindtibia.

D. antiqua does look possible - if there is a pre-alar after all  So hard from photos! |

Sorry for the late reply and THANKS A LOT to you both for your input, Joke and Stephen!!  I am adding a couple of pictures where the chaetotaxy can be seen better. Do you mean prealar bristles? I am going to look if there is any picture showing this better. Piluca_Alvarez attached the following image:  [146.63Kb] |

I think Delia is right, with a possibility it could be D. antiqua, I don't dare to go futher.... I added a photo to show the prealar seta.. javanerkelens attached the following image:  [175.48Kb] |

Well, again too late but here is finally a shot of the lateral bristles on thorax. Sorry quality isn't the best, but there isn't anything better  Hope it helps

I agree with Joke that all we can say is that the lack of a strong pre-alar rules out D. platura. D. antiqua may be possible (it has a weaker pre-alar), but we'd need better evidence to go beyond 'Delia sp.' |

Thanks a lot again, Stephen! I cannot provide better evidence so I know now that definitely all we can say is Delia sp.. Good enough for me! Many thanks to you both for your input and interest!! |
