Is it possible to identify females of Sylvicola? Think this one is cinctus or fenestralis.. Size is approx. 5 mm. Photographed in Bodø, northern Norway. Date: 10.04.2012. Geir79 attached the following image:  [141.22Kb] |

Hello Geir  There is a key (Norway) here: Søli, G. E. 1992. Norwegian species of Sylvicola Harris, 1776 (Diptera, Anisopodidae). Fauna Norwegia B 39:2 s. 49-54 Download from: www.entomologi.no Halvard Hatlen Møre og Romsdal, NORWAY |

An even better one can be found at http://online-keys.net/infusions/keys/keys_view.php?key_no=1. It is based on Søli's key, but contains further species; one of which (stackelbergi) recently was found in Norway. |

Thank you : I've already used the key for all the palaearctic species (to get to cinctus/fenestralis). I've checked the distance between the basis of veins M1-M2 and M2-M3 with my USB microscope, have I done it correctly? The ratio between M1-M2 and M2-M3 is 1,5 from my measure, so it is S. fenestralis? Geir79 attached the following image:  [111.4Kb] |

Hello Geir, Cool you bring it up. Since that character is accompanied by a questionmark, i have always wondered if it is a valid one. Hope someone with the right knowledge will react to this... Edited by Auratus on 11-04-2012 10:56 Greetings, Jan |

Hi all, This is a female of Sylvicola sp. (fenestralis/cinctus); taking that character into account, should be S.cinctus

None recent key does use this feature for ID. Genitalia in males and genital fork + hypoproct + cerci + hypogynal valves in females. Dissect more specimens of cinctus/fenestralis/zetterstedti and try to confirm this hypothesis. We will see, what your results show to us  Libor |
