Found at Burn of Valayre a couple of days ago. Looks like a Rhaphium, the only one recorded previously here is Rhaphium brevicorne [Curtis]. Any possibility of knowing if this is it from a photograph, or does it need its genitalia inspected?

Rhaphium brevicorne: Postpedicel 4‒5 times longer than high at base; stylus more than half length of postpedicel, sometimes as long as postpedicel. It need its genitalia inspected. Igor Grichanov |

Dear Igor, on the pictures above the arista (stylus) seems to be distinctly shorter than half of the first flagellomere (postpedicel). Stefan |
