Distribution.

This taxon is widespread throughout the southeastern Alps, from Val Sugana in the west, Alpi Venete, Alps of Belluno and the axis Ampezzo-Pordenone in the east (Italy) ( Nordsieck 1963b: 175).

Specimens examined.

Italy, Veneto, Serravalle (L.T.) near Vittorio Veneto. 500 m asl, 46°00'4.46"N, 12°17'11.13"E, W. De Mattia and J. Macor leg. and det., 3 dissected spm .; 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 .

External morphology of the genital organs

(Fig. 48 .3). The V is as long as the FO. The FDBC is as long as the SDBC+BC. The BC+SDBC is cylindrical, short, with no distinction between the SDBC and the BC. The D is slightly shorter than the SDBC+BC. The V is cylindrical and long, thin in diameter. The PC is approximately as long as the V. The P is swollen and wide in diameter and the transition between P and EP is clearly visible. The PR is short and robust. The E is almost as long as the P but thinner in diameter.

Internal morphology of the genital organs

(Fig. 48 .4). The A and the V are smooth, with of almost undetectable longitudinal elevations. The P presents weak tubercles longitudinally arranged along irregular lines. The PP is smooth and elongated. It is small comparing to the whole penial volume. The PP originates from the ER, which is connected with the ELP. The epiphallar formula is: PP(ER(ELP)). The E shows two fringed ELP. They proximally fade before the VD.

Remarks.

The actual status and validity of C. itala serravalensis , especially in relation to the nominate subspecies, must be further assessed with more field research and morphological/genetic molecular studies.
