APOIDEA OF FRIULI VENEZIA GIULIA AND SURROUNDING AREAS. II: APIDAE. In this second paper, data on systematic entities of the Apidae family (sensu PAGLIANO, 1995) are presented; many hundreds of specimens collected by the Authors or conserved in University and Museum collections were studied. For some species, in particular belonging to the genus Bombus LATREILLE, regularly collected for several years in the same places, the flowering plants visited are also reported. In the whole, 48 bee species or subspecies of the genera Xylocopa LATREILLE (3), Ceratina LATREILLE (6), Bombus LATREILLE (29), Psithyrus LEPELETIER (9) and Apis LINNAEUS (1) were examined. The species Bombus gerstaeckeri MORAWITZ, B. jonellus martes GERSTAECKER and Psithyrus quadricolor meridionalis RICHARDS are recorded for the first time to the Friuli Venezia Giulia region. Bombus distinguendus MORAWITZ and B. pomorum PANZER - correctly unmentioned in the Checklist of the species of the Italian fauna - were collected in surrounding areas (Istria) of Friuli Venezia Giulia. Other four species, including in the genera Ceratina, Bombus and Psithyrus, mentioned in the literature but not found by the Authors in the examined collections, are separately mentioned. Some modifications to the Checklist of the species of the Italian fauna are also proposed. By the evaluation of several data on the flowering plants visited by wild bees, it is possible to point out that almost all the species including in the genus Bombus are polilectic, favoring the pollination not only of cultivated plants but also of spontaneous ones, included those of natural interest. Only B. gerstaeckeri, among the considered Apidae, seems to be a oligoleptic species, specialized on Aconitum spp. (Ranunculaceae).

Abstract
APOIDEA OF FRIULI VENEZIA GIULIA AND SURROUNDING AREAS. II: APIDAE. In this second paper, data on systematic entities of the Apidae family (sensu PAGLIANO, 1995) are presented; many hundreds of specimens collected by the Authors or conserved in University and Museum collections were studied. For some species, in particular belonging to the genus Bombus LATREILLE, regularly collected for several years in the same places, the flowering plants visited are also reported. In the whole, 48 bee species or subspecies of the genera Xylocopa LATREILLE (3), Ceratina LATREILLE (6), Bombus LATREILLE (29), Psithyrus LEPELETIER (9) and Apis LINNAEUS (1) were examined. The species Bombus gerstaeckeri MORAWITZ, B. jonellus martes GERSTAECKER and Psithyrus quadricolor meridionalis RICHARDS are recorded for the first time to the Friuli Venezia Giulia region. Bombus distinguendus MORAWITZ and B. pomorum PANZER - correctly unmentioned in the Checklist of the species of the Italian fauna - were collected in surrounding areas (Istria) of Friuli Venezia Giulia. Other four species, including in the genera Ceratina, Bombus and Psithyrus, mentioned in the literature but not found by the Authors in the examined collections, are separately mentioned. Some modifications to the Checklist of the species of the Italian fauna are also proposed. By the evaluation of several data on the flowering plants visited by wild bees, it is possible to point out that almost all the species including in the genus Bombus are polilectic, favoring the pollination not only of cultivated plants but also of spontaneous ones, included those of natural interest. Only B. gerstaeckeri, among the considered Apidae, seems to be a oligoleptic species, specialized on Aconitum spp. (Ranunculaceae).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
