Charpentieria itala clavata ( Rossmaessler, 1836)

Figs 46.1-46.3, 47.9

Distribution.

This subspecies is known to occur in central-western Lombardia, in the provinces of Bergamo and Lecco ( Nordsieck 1963b; Nardi 2011).

Specimens examined.

Italy, Lombardia, Lecco , Ballabio. 710 m asl, 45°54'25.96"N, 09°25'55.16"E, W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 46 .1). The V is slightly longer than the FO. The FDBC is longer than the SDBC+BC. The BC+SDBC is cylindrical, with no clear distinction between the SDBC and the BC. The D is longer than the BC+SDBC. The V is cylindrical and long. The PC is ~ 1.5 × longer than the V. The P is conical and the transition between P and EP is not clearly visible. The PR is short and robust. The E is shorter than the P but shows almost the same diameter.

Internal morphology of the genital organs

(Figs 46 .2, 46.3). The A and the V show irregular smooth folds that continue proximally inside the P. The P, as the V and A, does not present a regular pattern of pleats but a combination of irregular smooth folds. The PP is very big, folded with a wide base. It occupies the whole penial volume and reaches the A. The PP originates from the epiphallar wall and it is connected with the ELP. The epiphallar formula is: PP(ELP). The E shows two moderately fringed ELP. They proximally fade before the VD.
