Hello, is Limnia unguicornis correct here? The fly is from last week from a wet forest near Neuss (germany). Length was about 6mm. Thanks, Michael Michael Becker attached the following image:  [40.6Kb] Edited by Michael Becker on 17-08-2010 19:09 |

Limnia is correct, and then the uniformly brown vitta on scutum suggests the rarer Limnia paludicola.

Hello Stephane, thank you for your answer. Now that you say it I see the difference to L. unguicornis too. Is idenfication certain enough for the gallery, which still lacks L. paludicola? Michael |

Well, I have never met L. paludicola myself, but females with brown band are keyed out as L. paludicola in all litterature. If I find a species like this, it is the name I would give to it ! After, I don't know if it makes certain the identification...

It is my personal opinion, so far I'm not ready to give proof of it. I don't think that palludicola is a valid species. Nikita Vikhrev - Zool Museum of Moscow University |

Hello Stephane, Nikita, if we accept L. paludicola, then I guess, if all literature leads to this species, we can assume, the identification is correct. Even genetic or genital examinations are not 100% certain. Whether to accept the species or not I let Paul decide. Michael |

Paul's, Stephane's and mine opinions are the same: so far as nobody publish anything palludicola is a valid species. I only wrote that at my unofficial opinion palludicola smells as species make up out of whole cloth (as well as several other Sciomyzidae, Euthycera sticticaria, for example). As for palludicola: 1. The difference in genitalia are very doubtful my test, the matter of piont of view. 2. The colour of midstrip in female? Why not a variation? 3. The marriage of palludicola males and females. Nobody collected and examined any copulation pairs of palludicola, as far as I know. What is the reason to regard such males and females as conspecific? I can't see any...
