Hi, I found this fly on Fomes fomentarius (21/04/2011). I keyed it as Odinia boletina, but since I have been told that these keys are not very reliable I'am asking your opinions.

There is a presutural dorsocentral, which makes this Neoalticomerus: as this seems to be a female, I cannot get you much further.  |

@Phil: Is there any other Neoalticomerus species known from Europe besides N. formosus?

Good point! There's only one species mentioned in Fauna Europae. |

Laszlo Papp and I have a paper in preparation on the (now) 3 species of Neoalticomerus in the Palaearctic. One of these (which will be called mongolicus) is only known from Mongolia (surprise). The other is to be called fabricei. it is very distinctively different from formosus on the male genitalia, but other, subtler differences exist, although I am not certain if these work for all females: anyway, here goes - formosus has no intra-alar striping on the mesonotum and the white part of the prefrons (the facial plate) is wider than the dark part; the frontal triangle extends beyond the middle. The reverse of all these is true for fabricei. From what can be seen this specimen should be a formosus. By the way, these names are not to be used until they are published. |

I think I caught a male this time, it's a lot smaller than the female... |

Looks right - you need to tease out the genitalia to be sure ! |

These are also from Belgium, they seem similar. Same species ? Joris  |

Not totally sure about the dorsocentrals, but may well be...What were the circumstances of these photos ? |

On the underside of Fomes in an old beech forest (so the pictures are rotated 180°). I have collected a few, so I can make extra pictures or send them to you. There's only one species of Odiniidae in the Belgian catalogue, so it would be interesting to know the exact name. Joris

Cut off the last abdominal segment including the genital capsule. Soak it for a while (about an hour, say) in cold KOH. It should then be pliable and you can open out the capsule to reveal the structures. Wash in water and photograph - then wait for me to be conscious and I should be able to tell all... |

Oké, I'll try to find some KOH first. Can take a while... |
