Figs 51.4-51.8, 56.2

Specimens examined.

Italy, Trentino-Alto Adige, Trento, Fai della Paganella. 600 m asl, 46°12'57.04"N, 11°04'22.88"E, W. De Mattia and J. Macor leg. and det., 3 dissected spm .

Distribution.

Massif of Mount Paganella, Trentino-Alto Adige, Italy ( Zallot 2001: 154).

External morphology of the genital organs

(Fig. 51 .4). The V is shorter than the FO. The FDBC is slightly shorter than the SDBC+BC. The BC+SDBC is cylindrical 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 short and wider in diameter along its distal part. The PC is ~ 3 × longer than the V. The P is cylindrical. The transition between P and EP is clearly visible. The PR is long and thin. The E is longer than the P but thinner in diameter along its proximal part.

Internal morphology of the genital organs

(Figs 51 .5-51.8). The A, the V and the P show many more or less irregular, mostly smooth longitudinal pleats. The hemipapilla is smooth and short. The outlet of the hemipapilla is triangular. The E shows two fringed ELP. They proximally fade before the VD.
