Distribution.

This subspecies is known from Val Serina (province of Bergamo, Lombardia), Italy ( Nardi 2011: 101).

Specimens examined.

Italy, Lombardia, Bergamo, Val Serina , Loc. Galleria, Bracca. 45°49'24.49"N, 09°43'6.73"E, W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 45 .4). The FO is 1.5 × longer than the V. The FDBC is extremely short. The BC+SDBC is club-like, with no distinction between the SDBC and the BC. The D is longer than the BC+SDBC. The V is cylindrical. The PC is double as long as the V. The P is slightly swollen at its proximal part with a clearly visible transition between P and EP. The PR is long and robust. The E is slightly longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Fig. 45 .5). The A and the V are almost smooth, with fine and barely visible longitudinal elevations. The P shows 3 oblique fringed pleats that proximally are not connected to the ER. The PP is fringed and occupies almost the whole penial internal volume. The PP originates from the ER that is connected with the ELP. The epiphallar formula is: PP(ER(ELP)). The E shows two remarkably fringed ELP. They proximally fade before the VD.
