Forum Entomologi Italiani

Trovato sotto una lamiera in una zona di prato incolto, in compagnia di una colonia di Lasius.
Lunghezza: 15 mm
Ho pensato allo S. dimidiaticornis Gemminger, 1851 per la forma del capo, ma non ne sono sicuro.
A voi la parola!

I see! They're very similar to the genus Staphylinus to me! Thanks a lot!
So I'd say it's not latebricola because it's too big and because antennas, middle and back femoras are black I'd determine it as Platydracus chalcocephalus (Fabricius, 1801)
am I correct?

Yes, whatching it closely the shape of the head is different, it's not arrow-like as in calcocephalus! Is it a stercorarius? Still I'm a bit confused because my specimen's legs and antennas are exactly like those of a calcocephalus, but I think it's normal in the variety of the insect then, as in the post you linked me there was this same problem with colours... thank you so much for the help and patience!

E' Platydracus stercorarius. P. calcocephalus in Italia si trova solo vicino a Trieste.

Platydracus chalcocephalus (Fabricius, 1801)

In Italia le uniche segnalazioni sicure si riferiscono al Carso (Pilon 1998)

Oh, it's calcocephalus? So the datas of this specimen have some value! If so I'll accept to give the specimen to anybody that needs it for study purposes. If you want it just ask!

no solo il testo del titolo (Platydracus chalcocephalus (Fabricius, 1801) In Italia le uniche segnalazioni sicure si riferiscono al Carso (Pilon 1998)

credo che (99,9% Platydracus stercorarius (Olivier, 1795)
