Charpentieria itala albopustolata is widely distributed throughout the Central Alps of Lombardia ( Nardi 2011 : 101) and a small area of southwestern Veneto, next to the southern part of Garda Lake (F. Scarlassara pers. comm.) and Verona. Specimens examined. Italy , Lombardia , Brescia , city castle walls. 200 m asl , 45°32'29.87"N , 10°13'28.37"E , W. De Mattia and J. Macor leg. and det., 2 dissected spm . External morphology of the genital organs (Fig. 44 .5). The FO is almost 2 x as long as the V. The FDBC is much 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, thin and with a round apex. The V is long and thin. The PC is double as long as the V. The P is long and swollen at its proximal part. The PR is long and thin. The E is very short and thin in diameter. The overall appearance of the external morphology of the genital organs is slim and elongated. Internal morphology of the genital organs (Fig. 44 .6). The A and the P are smooth, with very loose and barely visible longitudinal elevations. The V is smooth. The PP is folded, elongated with a pointed apex. The ER is present and it is connected with the ELP by means of 5 or 6 small longitudinal pleats. The PP originates from the ER. The epiphallar formula is: PP(ER+ELP). The E shows two fringed ELP. They proximally fade before the VD.
