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 View Figure 7 ) of a pair of specimens mating on the bark of a poplar in Crava Morozzo Natural Reserve (Fig. 8 View Figure 8 ).
