Distribution
The species is known with certainty for
Italy
only in
Lazio region
in a single locality where it is very abundant (
Prestininzi 2009
) and in
Piedmont
historical data during the 19
th
century with the label " Turin " (
Sommaggio 2007
).
Notes
Six specimens
of this species were collected in the
Piedmont region
in the 19
th
century (
Sommaggio 2007
), but recent research in lowland forests failed to collect it until one of the authors (
ST
) took a couple of photos (Fig.
7
) of a pair of specimens mating on the bark of a poplar in Crava Morozzo Natural Reserve (Fig.
8
).
