A checklist of the Psylloidea of Canada

The Canadian psyllid fauna is often lumped together with the USA fauna in checklists, and at least 354 species of psyllids are currently known to occur in the region consisting of the United States and Canada. However, many of the species found in the lower USA do not occur in Canada, and so a more focused regional checklist felt necessary to better understand the Canadian fauna. Herein I list the 119 species which are currently known to occur in Canada, but undoubtedly there are many undocumented species which likely also occur within the country.

14 species are considered to be non-native to the region; introduced species are listed in italics. Species not known to occur outside of Canada are listed in bold. Provinces in which a species has been recorded are listed with the westmost province first and then continue from west to east. The host plant (if known) is recorded following the distribution.

Host plants

The host plant genera for Canadian Psylloidea are listed, followed by the number of species known from that host. Some genera are grouped together based on recent changes in plant taxonomy that make it difficult to understand historical host plant records, or by a tendency of certain psyllid species groups to use multiple related genera of plants. Of the 44 host plant genus or genus groups known to be associated with psyllids in Canada, 21 of them are host to more than one species.

Hi Chris, Just a note that the Canadian fauna was updated in the Checklist of Hemiptera of Canada and Alaska, although there have been a few additions and nomenclatural changes since then. Footit (2019; see https://zookeys.pensoft.net/article/26574/) review of the Hemiptera of Canada also indicates that there are 129 species in Canada. A few from you list are newer additions so it appears that the number is still larger than that, and a few additions not yet published bring it still higher. that being said, it is a great list to have the host info associated with the names and it is interesting to see some of the recent changes to the nomenclature
