Another chaotic genus in the Iberian Peninsula :(

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

Thanks :)

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 :o Probably I am missing something.

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

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! :) :)

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! :) I shouldn't work on Saropogon when I am ready to go to sleep, hehehehehe... ;)

Well, remember all the trouble Saropogon brought last year ;) 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 ;)
