Hello everybody, only rarely I take doli's home. As far as I can remember I do not remember to have seen this species before. I think it is a Rhaphium. In the field, with the naked eye I saw the strongly metallic purple-blue forehead and whitish face. Of course the antennae are remarkable though not as R. longicorne. Any suggestion? rvanderweele attached the following image:  [76.81Kb] ruud van der weele rvanderweele@gmail.com |

But R. longicorne has much longer antennae, hasn't it?

besides, I forgot to remark, Stefan, the first segment of the antenna is thinner than the 2nd.

Thanks, Stefan, I didn't check the photo in the gallery before, because I checked the literature, which mentions the antennae etc. Besides I have seen some other picturesof D. longicorne, which shows even longer antennae. I have to say that I am absolutely no doli expert. Rather the opposite; I take rarely dolis home for identification. ruud van der weele rvanderweele@gmail.com |

Female of Rhaphium longicorne (your photo) has shorter antenna than that in male.
