Clausiliidae (Gastropoda, Pulmonata) from Lombardy (northern Italy), with the description of a new subspecies

New biogeographic and taxonomic data on Clausiliidae from Lombardy (northern Italy) are presented. Cochlodina fimbriata fimbriata (Rossmässler, 1835) has been found for the first time in this region. Charpentieria itala rubiginea (Rossmässler, 1835), hitherto known only from the Valtellina (province of Sondrio), is recorded in eastern Lombardy (province of Brescia). Charpentieria clavata tiesenhauseni (Gredler, 1855) and Charpentieria clavata trepida (Käufel, 1928), two little known subspecies, which were only known from the type localities, have been recorded at new stations. Moreover, Clausilia umbrosella Nordsieck, 1993, until now considered endemic to Valle Caffaro (Caffaro river Valley), has been found at several places in the Valle Trompia (Mella river valley) and Valle Sabbia (Chiese river valley). Charpentieria clavata triumplinae nov. subspec. is described on the basis of shell characters. It is known from an area between the high Valle Trompia and Valle Sabbia and from an isolated population from near Monte Tremalzo, NW Garda Lake, at the boundary between the provinces of Brescia and Trento. Acheck-list of the Clausiliidae known from Lombardy is added.
