I need help to identify this nice fly seen in Portugal. Maybe Chloropidae? Location: Óbidos, Portugal Date: 20/09/2012 Rui Andrade attached the following image:  [47.33Kb] |

Perhaps Aphaniosoma in Chyromyidae, but I have never seen them 'in the flesh'.

Hi Paul! Thank you for your help. I uploaded a photo of a “normal” Aphaniosoma. It looks different from the one above.

I know there are pale and dark species and their posture is similar...

Wings look like Asteia (Asteiidae) to me, though the head (especially from above) looks like Teratomyzidae. |

Hmmm, interesting, thank you Eric! I'm very confused about this fly! |

What about Astiosoma rufifrons?

Jan, I believe Astiosoma (also in Asteiidae) has a posterior cv. (dm-cu), which Rui's fly seems to lack. Rui: there is a third family in this mix: Xenasteiidae; these, asteiids and teratom's are all very closely related, and your fly is certainly one of these three. Unfortunately, all my printed literature is still at CDFA, and I now have access only to the common, internet-based stuff (which doesn't help here). There is a person who could ID your interesting fly at a glance: Dr. Amnon Friedberg, of Tel Aviv Univ. |

I had not seen the wing venation before. It is Asteia. I know of at least two species with such flattened heads, A. tunisica and A. floricola, of which the former seems tio be the more likely one.

Thank you Jan, Eric and Paul. Yes, dm-cu is indeed absent. I’ve seen the drawings of A. floricola and A. tunisica heads and they look very similar to the species I found! I have been sending asteiids to Dr. Jindrich Rohacek so I’ll contact him to see if he is interested in seeing this species. |

Much obliged! Another species of the same group might be Asteia ibizana but I think that species has the head less flattened.

This really should be A. tunisica. The eye is at least twice as long as high and this is less in all other Asteia with elongate head.
