Are the palpi black? Chamaemyiids are risky, especially females. But using Bei-Bienko, the combination 1)palpi black; 2)tibiae and tarsi yellow and 3) yellow spot near base of arista on 3rd segment of antenna, quickly keys out C. emiliae, which is an eastern species that is listed in the finnish draft catalogue. Might be correct? Maybe Steve Gaimari has something to say about this? |

Using the old Bei-Bienko key is dodgy to say the least to identify Chamaemyia...

...indeed. It is almost a crime.  ...but yet not worse than using it to identify Leucopsis females! If we get a male with genitalia I´ll pick up good ol´Tanasijtjuk 1986, but the russian keys are still too difficult for me (even with Igor´s excellent russian-english dictionary för entomologsist) to understand it to identify females, if it even is possible. EDIT: 1986, not 1987 Edited by viktor j nilsson on 18-01-2010 17:51 |

Might be correct? Maybe Steve Gaimari has something to say about this? Females of Chamaemyia (and Leucopis) are notoriously difficult. Especially when using Bei-Bienko! But really, even with Tanasijtshuk's 1986 work, most females are impossible. The male genitalia are the thing! Only the very obvious species are possible from photographs, in any case. |

With all the species being variable and more or less close to each other, Chamaemyia females are all but impossible. This one if definitely not C. emiliae. If I had to guess, I would say either C. sylvatica or the species formerly called C. juncorum (it's apparently nameless not  ), but your guess is as good as mine.
