Routine weevil and bark beetle identifications from plant health surveys, amateur collectors, public inquiries, and museum survey specimens regularly produce new faunal records for Canada, its provinces, and territories. The most recent checklist of the Canadian fauna is
The present article presents new findings with associated collection data so that the records may be documented with verifiable voucher specimens. These records are also reflected in the updated checklist of Canadian beetles (
Specimens were identified (or identifications confirmed) by recognized specialists in those taxa. These are as follows:
All collections listed below were reviewed by one or more authors for undocumented curculionoid records except for DEBU, GLFC, and City of Saskatoon. For these three collections we included only the specimens identified as new by their staff. It is possible that additional undocumented curculionoid records remain in most of the collections listed below.

This widespread native species, known from all other provinces and two territories, attacks the lower parts of dead and dying conifers. The absence of records from Nova Scotia seems to be an oversight.

This native species was only known from the type series, collected in 1978 near Fairbanks Alaska. The Alberta specimens mentioned here represent a significant extension of the known range to the south and east. Both the type series and all specimens reported here were captured in CFIA traps baited with ipsenol lure.

This work represents the research activities of many people and organizations: field collecting, sorting trap samples, preliminary identifications, and providing loans, as part of their ongoing efforts to document their regional insect fauna. Some bark beetle records are based on CNCI specimens that D.E. Bright had identified. The authors thank I. Nei and K. McLachlan-Hamilton for assisting with identifications; Jeff Boone (City of Saskatoon), Stéphanie Boucher (LEMQ), Claude Chantal (CCCH), CFIA’s Plant Health Survey Unit and inspectors, Tom Hutchison and Sunil Ranasinghe (Alberta Environment and Sustainable Resource Development), Serge Laplante (CSLA), Rory McIntosh (Saskatchewan Ministry of Environment), Kathryn Nystrom (Great Lakes Forestry Centre), Steven Paiero (DEBU), and Irene Pines (Manitoba Conservation) for providing specimens (often already identified).
