Distribution and remarks.

The actual distribution of C. itala itala depends on the status and validity of other subspecific taxa with similar shell morphology, especially C. itala serravalensis or other available names of uncertain validity as Clausilia itala vicentina Schmidt, 1868 or Clausilia alboguttulata var. a, major Pirona, 1865. Following the original descriptions ( Pirona 1865: 693; Schmidt 1868: 47), both taxa probably have “overlapping“ distribution with the nominate subspecies, being cited for the surroundings of Vicenza and the western Friuli plain. According to the current systematics, C. itala itala is distributed in the Pianura Veneta (Venetian Plain), Colli Euganei and Berici, including the Prealpine hills of Vicenza.

Specimens examined.

Italy, Veneto, Vicenza, San Donato , Barbarano Vicentino. 300 m asl, 45°24'22.30"N, 11°31'11.93"E, [Lab ID C1_1, COI: MW758952 ], W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 44 .1). The FO is almost as long as the V. The FDBC is longer than the BC+SDBC. The BC+SDBC is club-like, with visible distinction between the SDBC and the BC. The apex is rounded. The D is slightly longer than the BC+SDBC with a round apex. The V is long and partially swollen. The PC is only slightly longer than the V. The P is short and remarkably swollen. The PR is long and robust. The E is slightly longer than the P and thinner in diameter.

Internal morphology of the genital organs

(Fig. 44 .2). The A and the P present big transversal pleats. The pleats are smooth and discontinuous along the distal part of the P and in the A. The V is smooth. The PP is smooth, elongated with a round apex and directly connected to the ELP. The epiphallar formula is: PP(ELP). The E shows two ELP, fringed at their distal ends. They proximally fade before the VD.
