Additions to the knowledge of the aphid fauna in the Veneto region north eastern Italy (Hemiptera Aphidoidea)

An updated checklist of aphids detected in Veneto region (NE Italian peninsula) is reported. This list follows a previous one published in 1994, where 130 aphid species were checked for the same regional area. At present, our available data refer, as a whole, to the presence of 332 species, distributed into 106 genera. Six of the species reported are new records for the Italian aphid fauna. For each of the listed taxa short informative notes are given on their previous records (if any) in current literature and/or their collecting data (i.e. host plant species, localities and dates for each of the available samples). In addition, and whenever useful, more extensive faunistic information is given on a few of the most relevant species listed. Short accounts are added, at the end, on the regional biogeographical pattern of the listed aphid species as a whole.
