Distribution.

Charpentieria stenzii paroliniana is known from the lower Valle del Brenta from Carpanè, Cismon del Grappa to Primolano, and surrounding mountains on the right bank of the Brenta River (Foza, Vicenza, Veneto), Italy ( Nordsieck 1963b: 196).

Specimens examined.

Italy, Veneto, Vicenza, Valstagna, Foza , Loc. La Goccia. 800 m asl, 45°52'29.20"N, 11°38'59.73"E, W. De Mattia and J. Macor leg. and det., 3 dissected spm .

External morphology of the genital organs

(Fig. 55 .3). The V is much shorter than the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is club-like in shape, with a more or less clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and slightly thinner. The V is short but wide in diameter. The PC is ~ 2.5 × longer than the V. The P is cylindrical and slightly swollen. The transition between P and EP is clearly visible. The PR is long and robust. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Figs 55 .4-55.5). The V is smooth. The P shows three to four irregularly fringed pleats that continue as far as the A. The hemipapilla is very short, conical and moderately folded. The outlet of the hemipapilla is triangular. The E shows two fringed ELP. They proximally fade out before the VD.
