First, I agree that the Fauna Europea isn't a scientific work and there is a great need to use other publications.
Yes, there are some differences between the British Island and Continental Europe. Usally I'm really not so interested in creating synonyms, because we have a very high diversity and low knowledge on it. In the case of D. hyalipennis
and D. baumhaueri
it is necessary to check material from different parts of Europe. There is a high variation and I agree with other authors to synonymize D. baumhaueri
If somebody else is really interested in separating, it is a must to repeat this work.
In other cases, like the Choerades marginata
- group it seems to be that we have similar problems - but different results. People, like Malcolm Smart, are working on it.
We should have a look on the complete population of a species, but this isn't possible. Sometimes we find good evidence for separating, in other not.
