The length of the body is usually between 12–14 mm in A. burmeisteri, while in A. assimile it is usually between 10–12, exceptionally up to 13 mm. The coloration is also different: A. burmeisteri is lighter, sandy yellow-brown, while A. assimile is usually darker brown. Also, the length ratio of terminal tarsomere of anterior leg and its claws are different.

Grazie Daniel, inserisco la foto di una coppia dei miei esemplari, le dimensioni della mia serietta di 22 esemplari vanno dai 10 ai 14 mm. Ho ancora dei dubbi...  _________________

Length of the body is from head to apex of elytra, not to apex of pygidium! I can say for sure your specimens are not A. burmeisteri. It seems to be A. assimile but it's possible that in Italy are new and still not described species. What was the flight time of your specimens?

So, probably new species or subspecies. The best specialist in the genus Amphimallon is Olivier Montreuil from Paris - maybe he might be interested.
Typical individual of A. assimile from Romania:

Also, the length ratio of terminal tarsomere of anterior leg and its claws are different. May I ask what is the reference for these diagnostic characters? I do not remember they were cited in the last taxonomic assesment of the two taxa (Rössner E. & Krell F-T., 2001) As I don't read German, I may be wrong, sure they are not considered in the key at the end. (Rössner E. & Krell F-T., 2001.

Terminal tarsomere of anterior leg is longer, and its claws shorter in A. burmeisteri than in A. assimile, especially in females. This morphological feature has not been described yet.

Wow, a new diagnostic character between these two species would be a greatly welcome news!
By the way, re-checking the above mentioned paper, I came across a discussion about flight time of A. assimile (pag. 191). that I overlooked so far.
The population from Bibione (NE Italy) is treated as assimile but for that it is said "In northern Italy (Bibione) the species flew in the evening, but before dusk (M. LANGER, in litt. 1997)." (from Google translator :-))
I live in the same area and I can say that the population of my garden starts swarming before the time of astronomical sunset and ends after the sunset. The end of activity is difficult to assess, as darkness comes down while they are on flight, however that they are active during the dusk (=after sunset time), and rarely during the evening (rare specimens occurrying at light trap).

So it could be a new sp. or ssp.! But it would probably require genetic analysis.

 ciao a tutti Anch'io volevo sottoporre un paio di exx femmina raccolti alla sera dopo le ore 21:00 entrambi vicino alla casa (attratti dalle luci?). Pergine Valsugana TN 480 m/slm. Il piccolo misura 12 mm ed è stato raccolto il 21/06/2021 Il grande misura 14 mm ed è stato raccolto il 13/07/2020 Grazie mille per ogni chiarimento.
