IL GENERE Zospeum BOURGUIGNAT,1856 IN ITALIA(Gastropoda Pulmonata Basommatophora)CENSIMENTO DELLE STAZIONI AD OGGI SEGNALATE

The genus Zospeum Bourguignat,1856 in Italy(Gastropoda Pulmonata Basommatophora).Numbering of the known Italian stations.This preliminary work wants to be,above all,a numbering of theItalian stations where Zospeum has been found.The Author reports,besides the classical communications,aremarkable number of new localities which fill up important geographycal empty spaces of the Pre-alpine area,which goes from the Bresciano to the Slovenian border relating to the Jugoslav stations revised by BOLE(1974a).The systematic considerations are more wary(partly confirming again GIUSTI e PEZZOLI,1982 views)because,according to the Author discriminating shell characters of so many pointform populations,extremelyisolated from each other,have not arisen yet.This fragmentation has brought to strong characterizazion of theshell.We also have to wait for the response of the anatomical researches that are foreseen in a further work.
