Distribution.

Charpentieria stenzii cincta presents a wide distribution, approximately including in Italy the Alpi and Prealpi Carniche and Giulie, Dolomiti, Cansiglio and Monti Lessini ( Zallot 2001: 154), Stubai Alps (Tribulaun) and farther to the East: Alps of Carinthia and westernmost Slovenia.

External morphology of the genital organs (Fig. 52 .1).

The V is much shorter than the FO. The FDBC is slightly shorter than the SDBC+BC. The BC+SDBC is cylindrical to club-like in shape, without clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and thinner. The V is very short and wide in diameter. The PC is ~ 3 × longer than the V. The P is cylindrical and swollen along its proximal part. The transition between P and EP is clearly visible. The PR is short and thin. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs (Figs 52 .2-52.6).

The A, the V and the P show many more or less irregular (longitudinal to oblique) smooth pleats. The hemipapilla is smooth to moderately folded and usually short. The outlet of the hemipapilla is slit-like. The E shows two fringed ELP. They proximally fade before the VD.
