Looks like a Palloptera sp. to me. Possible to confirm family/genus or identify it to species? Photographed 30.09.2011 in northern Norway (outside my apartment). Size approx. 4 mm. Geir79 attached the following image:  [175.95Kb] Edited by Geir79 on 30-09-2011 23:25 |

Palloptera usta, I think

Thanks. Think it looks like this species too, but it is not on the Norwegian species list for Pallopteridae (have checked this) Can it be confirmed in any way? Should not be problematic to find another one (it was right outside my apartment..) |

I agree with Paul. This is Palloptera usta (or Toxoneura usta). According to Fauna Europaea (www.faunaeur.org) it is known from Norway.

Yes, thank you very much. It is listed as Toxoneura usta in the Norwegian species list, that's why I did not find it! |

I still have difficulty in accepting other generic names in Pallopteridae as used in the present classification on Fauna Europaea. As far as I know, at least some of the characters in chaetotaxy used to divide genera are subject to interspecific variation within some genera. Wing patterns (for what these are worth, of course) would lead to a completely different generic division. Can anyone confirm whether the present division is also supported by, for example, consistent differences in structures of the male genitalia?

Mesopleuron (= anepisternum) bare: Palloptera s.str. Mesopleuron with hairs or setae close to hind margin: Toxoneura (+ Temnosira in some authors). Libor |

My point: Within, for example, Pherbellia that is used to distinguish between groups of species. Why should it here be used to separate geenra while some species in two different genera then resemble each other more closely than species in the same genus? Are there other characters that, perhaps, are not used in the keys because they are impratcial in the key. For example male genitalia?
