Another chaotic genus in the Iberian Peninsula Sad

Let's wait for Reinoud's view, but I would suggest Saropogon leucocephalus. Do you have a more lateral view? It would help...

Thanks Smile

Well, it seems to fit the keys for S. leucocephalus to my eyes...

However, seeing this lateral view there is something wrong about the creature and I don't know what it is. This genus is a nightmare for me Shock Probably I am missing something.

Please, wait for Reinoud's opinion. I am not confident at all with this ID Sad

A clear picture of the side of the thorax would be welcome, but when i use our provisional key i get to S. obesulus. Because leucocephalus has no tomentum on the side of the thorax and this one does at the top of the mesopleuron. : )


But reading Engel description does not fit good ; ( We will have to rework the key ?

Now used key by Engel and i end up with obesulus again..... The colour of the legs don't seem to fit.... the dark femora and hind legs bother me a bit...

Thanks for your reply Reinoud! Smile Smile

I see now why I wasn't happy with my own ID. Not only there is indeed tomentum on top of mesopleuron but it is a male, and a male leucocephalus should have black mystax! Smile I shouldn't work on Saropogon when I am ready to go to sleep, hehehehehe... Wink

Well, remember all the trouble Saropogon brought last year Wink We already had serious problems with potential obesulus that didn't fit the description. I think the problem is that Iberian specimens weren't really studied in old works and variability hasn't been taken into account... Yes, certainly keys need to be reworked, ours included Wink
