Hi Helga

Clearly the male of latipennis ! Well spotted !
Yet another record from Central Germany.

I agree, it is latipennis. For me it is a fairly common species in the western Czech Republic. I have not similar big material from other parts of my country, but it is very probably common species in almost every forest with dense shrubby underbrush. Theo, do you have any relevant info from other countries? Rare everywhere?

Hi Libor

I don't have any concrete information on the distribution. Maybe it has simply been overlooked. It does not occur in the Netherlands and I would be surprised to see it from Belgium. Therefore, the record by Juergen from the Teutenburgerwald only 150 km. from the dutch border was a big surprise to me.
If I remember correctly, you mentioned that latipennis has been common in Czech Republic only for the last ten years ?

Hi Theo. Rhagio latipennis is included in the Red List of my country. It was published in 2005. Maybe the author did not known any exact data. Really I do not know. I know the present situation only. Today, I have examined the material from the Northern Bohemia (Jizerske Hory Mts. and Krkonose = Giant Mts.) and latipennis was common too in this material. So, I can say it is similarly common forest species as tringarius, notatus, or lineola.

That is funny, because over here both tringarius and lineola are common, ....., but notatus is known only from a few localities !
Apperently, what is true in Czech republic, does not need to be so in a region some 1000 km. away.

Of course, it is the fact and also the reason, why I asked you. Notatus is frequently trapped in my region, but in small numbers only, as lineola. Tringarius and latipennis are trapped in bigger numbers.
