I am new to muscids and the like, and would welcome a pointer to this small fly (5mm) taken 5 March on forest edge in N Scotland. Murdo syrphus attached the following image:  [32.45Kb] Edited by syrphus on 02-07-2013 15:44 |

Just to expand on what is not a very good pic, I reckon from Fonseca that it is Coenosiinae, and it seemed to slip neatly through to Lispocephala, but then I got lost. It seems to have 2 ad on the hind tibia, and the antennae are reddish at the base and the palps all reddish. Arista short-haired, costal spine short, abdomen grey, with 3 pairs of spots on tergites 3-5, scutellum with two dark spots. Hind tibia with the stronger anterior setulae, tarsus 5 all dark, and no tuft of bristles on sternite 5. If you have kept up, that takes me to the very unlikely L. pallipalpis, so if anyone can suggest where I have gone wrong, I will be grateful. M. |

Just to add some more, the eyes are very shortly and sparsely hairy, there are 2 pairs of pre-sutural acr and dc, and 3 pairs of post-sutural dc. M. |

From what I can see on the picture it is a male Lispocephala from the alma group. Maybe you can check the colour of the last tarsomere of the front leg?
Best wishes, Niels-Jan Dek |

I agree. To be IDed from genitalia and front tarsi.

Thanks for that. I am glad I was not too far off on my first attempt at that subfamily! The last tarsal segments are completely dark dorsally up to the basal set of bristles. Possibly a hint of reddish above that point. What are the genitalia characters I need to see? M. |

The end of the story is that I was right all along! This is L. pallipalpis, confirmed from the specimen by Steven Falk. This was previously unknown from anywhere near N Scotland, and is rare in S England - hence my initial doubts. Another male (I have found 3 in total) that I took a few days later is in the NMS in Edinburgh. M. |

Great ! If you find other specimens, please think about me.
