Figs 51.1-51.3, 56.1

Distribution.

Italy, Trentino-Alto Adige, including westernmost Dolomites in the surroundings of Schlern mountain, Val di Non and Passo della Mendola ( Nordsieck 1963b: 191; Zallot 2001: 154).

Specimens examined.

Italy, Trentino-Alto Adige, Trento , San Romedio. 730 m asl, 46°22'3.83"N, 11°06'31.84"E, W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 51 .1). The V is slightly longer than the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is cylindrical in shape without clear distinction between the SDBC and the BC. The D is longer than the SDBC+BC and thinner. The V is short and wide in diameter. The PC is ~ 3 × longer than the V. The P is cylindrical. The transition between P and EP is not clearly visible. The PR is short and thin. The E is slightly shorter than the P and thinner in diameter.

Internal morphology of the genital organs

(Figs 51 .2-51.3). The A and the V are smooth or with weak irregular convolute pleats. The P presents irregular and wide longitudinal pleats. The hemipapilla is smooth and very short. The outlet of the hemipapilla is roundish. The E shows two moderately fringed ELP. They proximally fade before the VD.
