Distribution.

Known to occur in central Lombardia, Italy ( Nardi 2011: 101).

Specimens examined.

Italy, Lombardia, Bergamo , Bedulita. 625 m asl, 45°47'16.15"N, 09°32'42.26"E, W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 46 .5). The V is almost 2 × longer than the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is club-like, with a more or less clear distinction between the SDBC and the BC. The D is longer than the BC+SDBC and slender. The V is cylindrical and long, slightly tapered along its proximal part. The PC is ~ 1.5 × longer than the V. The P is conical and the transition between P and EP is not clearly visible. The PR is short and robust. The E is shorter than the P but shows almost the same diameter. The whole genital organs show a slender appearance [recalling the ectomorph genital organs as in De Mattia et al. (2020)].

Internal morphology of the genital organs

(Fig. 46 .6). The V presents irregular longitudinal pleats that stop just before the A. The A the P are mainly smooth with barely visible longitudinal elevations. The PP is smooth, slender, elongated and slightly irregular in shape. It occupies half of the internal penial volume. The PP originates from the ER that is connected with the ELP by means of four Clausilia minor smooth longitudinal pleats. The epiphallar formula is: PP(ER+ELP). The E shows two moderately fringed ELP. They proximally fade before the VD.
