Distribution.

Charpentieria stenzii faueri is exclusively known from Col del Vento and Grigno (Trento, Trentino-Alto Adige) and Oliero (Vicenza, Veneto), Italy ( Bank 1987: 139).

External morphology of the genital organs

(Fig. 53 .1). The V is much shorter than the FO. The FDBC is as long as 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 robust. The E is as long as the P but much thinner in diameter.

Internal morphology of the genital organs

(Figs 53 .2-53.4). The A, the V and the P show many more or less irregular smooth pleats. The hemipapilla is long, smooth to moderately folded. The outlet of the hemipapilla is triangular. The E shows two fringed ELP. They proximally fade before the VD.
