This Doli was only 4 mm. Which genus could this be? Photos from 21 June 2013 Salom62 N, E 17 Ångermanland, Sweden. Thanks for your help in advance Regards Kurt Holmqvist kurt attached the following image:  [102.34Kb] Edited by kurt on 18-10-2013 19:19 |

Dear Kurt and John, Please, provide us with the characters that point out that this might be D. migrans. I don't see them. Cheers, Marc |

I followed Grichanov's key to northern European species, adding "possibly" because females can not be reliably identified and I could not see clearly the bend in M. Femora yellow Postocular cilia pale Mid basitarsus with dorsal seta Calypter with dark cilia Antenna dark Bend in M sharp Frons looks more blue than green to me |

Dear John, It is a tricky business to try to ID a species on basis of a picture and a key that might be questionable. See a.o. the antenna, which seems to have a scape with a paler ventral part. This implies that one of your characters is not correct, which renders your ID equally debatable. Unless I have very clear diagnostic and preferably decisive characters in a picture, I keep my IDs probable at most. Cheers, Marc |
