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.

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

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?

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...

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

I think that might be for us to verify. :D

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 |t
