this phoographed in 5.august.2008 in a hilly area, small clearing in a beech (Fagus) forest, ~700m. several specimens collected.

can be IDed further?

thanks,
cosmln

Dinera carinifrons, or possibly ferina.

Would certainly be nice to see specimens of all/any :D I have never seen ferina because it doesn't fly here but it should be easy in the keys :)

---

D. ferina is as common as the elks around here. ;) Especially now in the late summer. I can send you some samples, if interested.

Jaakko, the same is true for England.

Cosmln, the difference is easy, but I couldn't see it on the pic

DC 3 + 3 -> carinifrons
DC 3 + 4 -> ferina

Yup... common as English Elk ... Elephants or Dinosaurs for that matter :P

Hi Theo,

i have a lot to learn, and one of this is: what is DC? (i'm guesing some setae, but from where?)

i have some other angle, just to know what to search. :D

Dorsocentral. The bristles on scutum. SEE the Overviews, cosmin :P

Imagining a central line on scutum, we have FIRST a row of acrostichals (AT left, and at right in relation to that imaginary median line), then we have dorsocentral bristles. Better to see overviews. It has everything on thorax thread :P

for reference:

Acrostichal(s) seta(e) = ac seta(e). Or Ac seta(e).
Dorsocentral(s) seta(e) = dc seta(e). Or Dc seta(e).
Intra-alar(s) seta(e) = ia seta(e) not intralar or Intra alar.
Postsutural dorsocentral(s) seta(e) = post sut dc seta(e)
Presutural dorsocentral(s) seta(e) = pre sut dc seta(e)
Scutellum = sctl
Scutum = sct
Transverse suture = ts (on scutum) :P

thanks a lot Jorge.
right now is not easy to browse in threads.

Theo from the next image dc 3+4 this will go to D.ferina.

thanks to all for the help.

Sorry for dropping the DC, Jorge saved my ass, thanks.

And so it is D. ferina at last, a smaller male (DC 3 + 4), as well shown in this picture.
