...da quel che si vede da queste brutte foto direi Sericoderus sp. ma con macchie sulle elitre e testa piu' chiara del solito . Misura 1 mm. unico esemplare.

Io ne avevo trovati di simili su un pino morto a Torre Astura, ma erano più grandi.

the coloration is quite distinctive - I would look in Aposericoderus

...Luigi, questo era sotto foglie secche…

...Aleksei, Aposericoderus have 10 antennal segments ?

Vittorio, no, they have 11-segmented antennae, as well as the most of Sericoderus species. Only Sericoderus lateralis possesses not completely separated antennomeres 3 and 4 (10-segmented antennae), but the difference in segmentation is very subtle, and I'm not sure it can be seen without a microscope.

...thanks Aleksei, i see in my photo 10 segment antennae with 3 and 4 separated….but i do not have a microscope

Vittorio, the third antennomere in your photo actually consists of two antennomeres, which may be either completely separated one from another or separated only by a faint suture (see Figs. 167 and 176 in this book)

...no doubt for your identification ! I can't figure it out from my photos....see 10 segment.,.....in your pdf, however, it is understood very well thanks !....therefore Aposericoderus !
