Figs 46.6, 46.7, 47.11

Distribution.

The distribution of this subspecies is limited to Val Lorina and surrounding peaks, across the border of Trento and Brescia provinces (Lombardia and Trentino-Alto Adige), Italy ( Nardi 2011:101).

Specimens examined.

Italy, Lombardia, Brescia, Val di Lorina , Storo. 600 m asl, 45°50'23.18"N, 10°36'49.06"E, [Lab ID C3_2, COI: MW758954 ], W. De Mattia and J. Macor leg. and det., 3 dissected spm .

External morphology of the genital organs

(Fig. 46 .7). The V is half as long as the FO. The FDBC is very long, at least 2 × 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 slightly shorter than the BC+SDBC. The V is cylindrical and very short, wide in diameter. The PC is ~ 2 × longer than the V. The P is short, folded and wide in diameter and the transition between P and EP is clearly visible. The PR is short and robust. The E is almost as long as P and wide in diameter. The 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 .8). The A the V are mainly smooth with weak longitudinal elevations. The P presents strong irregular transversal smooth pleats. The PP is folded, irregular and elongated. It occupies almost the whole internal penial volume. The ER is found distally of the PP and not connected with it. The PP is directly connected with the ELP. The epiphallar formula is: ER+PP(ELP). The E shows two irregularly fringed ELP. They proximally fade before the VD.
