Hi * locality - Nave de Santo António - Serra da Estrela - PORTUGAL * date - 2007.09.02 * size - 11 mm (large fly) * habitat - openland at 1500 m * substrate - on ground I found this fantastic tachinid almost in the same place I caught the Bauhmaeuria microps. EDIT---> Title changed from "Tachinidae - Goniinae ?" to "Tachinidae - Trixa conspersa" and then to "Tachinidae - it was Trixa sp. (unknown genus.or maybe an Estheria??)" and"Tachinidae - Estheria picta (from Nave de Santo António)" jorgemotalmeida attached the following image:  [181.53Kb] Edited by jorgemotalmeida on 02-08-2011 20:16 |

I would say Trixa cf. conspersa Medium fly does not equal 6 mm. Trixa is much larger. SO I go for the medium-size. |

I was checking my notes in the size of the fly. It has 11 mm! Sorry for the mistake. I will edit right now! Edited by jorgemotalmeida on 02-08-2011 17:20 |

Well, that's good news, then there's little doubt this is Trixa. Quite Oestridae-like Tachinidae Theo |

So there is no room for doubts that this is Trixa conspersa, right? |

Unless it is a very rare species, it must be Trixa conspersa. That's why the cf. By the way, it is Dexiinae - Dexiini, not Goniinae (see title) Theo |

sorry for bother with this again... but if not a Trixa, could it be really an Estheria? Or never could be it at all? What would be the other possibilites if it wasn't a Trixa? Beware that Nave de St. António is rich in very rare species. (as it was already seen in 3-4 species waiting for species/or even genus name.) |

The small antennae suggest Trixa ... but perhaps Theo thinks it could be a different species

No, it cannot be a Trixa because Trixa has always BARE arista [LOOK at the second photo please - it is very clear that arista is..], and the arista is clearly hairy... SO what the heck is this Tachinid??

Yes, I was having second thoughts as well on Trixa, for another reason: the parafacial is hairy. It is bare in Trixa. So this really is a Estheria. And now we know what to look for: the crossvein r-m is darkered. Moreover, the humerus is clearly yellow. So it is Esheria picta Finally a result I am happy with.... Theo |
