Hi, This small fly I saw in Austria, Tyrol, Niederthai (1.500 m) in last August. The only flies with such dotted abdomen I know belong to the Muscidae; however, the eyes of this male are strange. Anthomyiidae might be another option... Help, please! Many thanks, Sundew Sundew attached the following image:  [163.21Kb] Edited by Sundew on 11-06-2011 18:24 |

Ah - a genus new for me - many thanks, Erikas! It resembles the male of thread http://72.44.83.9...pid=135710, so perhaps A. cilipes, too? |

I agree, Azelia cilipes or nebulosa. It is difficult to see whether it has a pd on t2 or not, or the number of av on t3.

I thought I saw the pd (for A. cilipes) in the first picture of post 2. |

I'm sure Claudia will find another photo showing it.

cilipes and nebulosa usually have different abdominal pattern: - lateral spots large, almost touch median spots - nebulosa - lateral spots small, well separated from median spots - cilipes This male has typical "cilipes" pattern. Nikita Vikhrev - Zool Museum of Moscow University |

Thank you Nikita, it's a useful information. Is it also available for females ? Azelia is a nightmare for me. I have many females undetermined because of the colour of the tibiae (can't make the difference between light brown ,brownish yellow etc.).

Stephane, I hear several doubts in one your question. At my opinion: 1. In West Palaearctic females nebulosa and cilipes seem reliably separated by t2 d preapical. (I hadn't checked female's abdominal pattern yet.) 2. Generally, keys for females aren't reliable at all even for Europe. 3. So far, I ignore females Azelia collected without males or label its as "collected with male of A. ..." 4. I have more than enough doubts in taxonomy of males, so I'm working on this problem as a first step. Nikita Vikhrev - Zool Museum of Moscow University |

Thanks Nikita, I feel less alone now ! Indeed, it was not only about A. cilipes/nebulosa, but for the other females.

Now. this is a really hot discussion! Let's go on with males - you wanted me to show you some more legs  . Here they are, though I am afraid the needed bristles might be less well visible. I am sorry I have no better legs to show (Azelia concerned)...

However, Nikita's point to different spot patterns is very helpful for me. So I guess I found also a male of A. nebulosa in the same place some days later. What do you say to this one?

1. The first new series of photos confirm our ID as cilipes, see image attached. 2. I can say, that I'm happy that my character really separate these 2 species OK. You are right, the second series is nebulosa. Nikita Vikhrev attached the following image:  [62.75Kb] Edited by Nikita Vikhrev on 12-06-2011 10:07 Nikita Vikhrev - Zool Museum of Moscow University |
