Charpentieria dyodon alpina is found in scattered populations along the Val di Lanzo, NW of Torino (Piedmont).

Specimens examined.

Italy, Piedmont, Torino, Margone, Val di Lanzo, Usseglio. 1500 m asl, 45°14'4.89"N, 07°12'18.90"E, leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 40.3). The FO is almost as long as the V. The FDBC is slightly shorter than the BC+SDBC (SDBC+BC). The BC+SDBC is cylindrical and longer than the V with no clear distinction between the SDBC and the BC. The apex is round. The D is shorter than the BC+SDBC, thinner with a round apex. The V is as long as the first duct of the BC+SDBC. The PC is 2 × as long as the V. The PR is long and robust. The E is slightly longer than the P and thin.

Internal morphology of the genital organs

(Fig. 40.4). The A and the P are smooth, with a very fine granulated sculpturing. The V shows many smooth longitudinal pleats. The smooth simple PP is simple, big, club-like with a round apex. Its base is partially connected to the ELP and transversally extends along the transition wall, narrowing the transition passage. The epiphallar formula is: PP(ELP). The E shows two main longitudinal moderately fringed pleats that proximally fade before the VD.
