Wing (as you no doubt realised, but one has to write something or the post doesn't work).

The same, in alcohol. The reason to doubt dorsata is that the hairs on the arista are shorter than the Fauna Ent. Scand. key suggests they should be. The only other possibility I can see is P. griseola. So, another opinion would be appreciated, please. John Bratton John Bratton attached the following image:  [88.74Kb] |

This is P. dorsata, not P. griseola or P. obtusa. Some characters in the key will not work for some individuals and in this case genitalia are still the best way for determination. |
