It's a female Helina. Could be Helina reversio, but impossible to be sure. Regards. Stephane. |

Hmm, I see an ad on mid tibia, so not Helina reversio. Helina sp.

I think Coenosia are small, this is a bit larger than Musca domestica... Stephane, I have more photos... what characters are important? thanks! |

Joke, Coenosia have 1 dorsocentral before suture, 3 beyond (1+3dc). Here, 2+4. Coenosia don't have prealar setae. Here there is one. Coenosia have 3 katepisternal (=sternopleural) setae arranged in equilateral triangle. Here, not the case. ...Coenosia have only 1 orbital bristle, here two... Javig, only a collected specimen could give a definite ID with this genus. Stephane. |

Not Coenosia. prealar seta is absent in ALMOST ALL Coenosinae..  and this fly has prealar seta. |

Stephane, I think that Helina reversio has ad on mid tibia. Why do you think it hasn't?

In d'Asis Fonseca key, couplet 39, page 51: ...Middle tibia without an anterodorsal bristle...duplicata Unless duplicata is not the old name for reversio in this book ? Stephane. |

Yes, Anthomyia duplicata (Meig.) = Helina duplicata = Helina reversio (Harris). And indeed, very variable species
