Could Lonchaea sylvatica be an option?

The specimen has yellow tarsomeres - so it is not L. sylvatica Fortunately it is a male so so you should be able to identify by examination of the genitalia. I have keys if you require them Iain MacGowan |

Eyes; bare or practically bare Anterior genal setae: multiserial Proepimeron: with a few well developed setae / setulae Legs; Tarsomeres obviously yellow/ orange ...And then I can't go on Scutellum; without setulae on margin anterior to lateral setae (Fig F). But my specimen is like Fig E, I cant't find a reference in the key.

Hi Sandra Well done for getting so far. Based on your description I would be reasonably confident that this is a male of Lonchaea patens. The large cercus is visible in your photo at the tip of the abdomen. The other two species in this part of the key - L. vagans and L. germanica are little known Best wishes ........
