The beetle fauna of Canada was assessed, including estimates of yet unreported diversity using information from taxonomists and COI sequence clusters in a BOLD (Barcode of Life Datasystems) COI dataset comprising over 77,000 Canadian records. To date, 8302 species of Coleoptera have been recorded in Canada, a 23% increase from the first assessment in 1979. A total of 639 non-native beetle species have become established in Canada, with most species in the Staphylinidae (153 spp.), Curculionidae (107 spp.), Chrysomelidae (56 spp.) and Carabidae (55 spp.). Based on estimates from the taxonomic community and our BOLD dataset, we estimate that slightly more than 1000 beetle species remain to be reported from Canada, either as new records or undescribed species. Renewed enthusiasm toward and financial support for surveys, especially in the central and western provinces of Canada will be critical for detecting, documenting and describing these species. The Barcode of Life database is still far from comprehensive for Canadian Coleoptera but substantial progress has been made and the number of Barcode Index Numbers (BINs) (as candidate species) has reached nearly 70% of the number of species reported from Canada. Comparison of BINs to observed species in a group of Canadian Staphylinidae suggests that BINs may provide a good estimate of species diversity within the beetles. Histeridae is a diverse family in Canada that is notably underrepresented in BOLD. Families such as Mordellidae, Scraptiidae, Latridiidae, Ptiliidae and Scirtidae are poorly known taxonomically in Canada and are represented in our BOLD dataset by many more BINs than recorded species.
对加拿大的甲虫动物区系进行了评估，利用分类学家提供的信息以及生命条形码数据系统（BOLD）中包含超过77,000条加拿大记录的细胞色素氧化酶亚基I（COI）序列簇，对尚未报告的多样性进行了估计。迄今为止，加拿大已记录到8302种鞘翅目昆虫，比1979年的首次评估增加了23%。共有639种非本地甲虫物种在加拿大定居，其中大多数物种属于隐翅虫科（153种）、象甲科（107种）、叶甲科（56种）和步甲科（55种）。根据分类学界的估计以及我们的BOLD数据集，我们估计加拿大仍有略多于1000种甲虫物种有待报告，这些物种或是新记录物种，或是未描述物种。重新激发对调查的热情并提供资金支持，尤其是在加拿大中部和西部省份，对于发现、记录和描述这些物种至关重要。生命条形码数据库对于加拿大鞘翅目昆虫来说仍远未全面，但已取得了实质性进展，条形码索引号（BINs）（作为候选物种）的数量已达到加拿大报告物种数量的近70%。将加拿大隐翅虫科一组中的BINs与观察到的物种进行比较表明，BINs可能为甲虫内部的物种多样性提供一个良好的估计。埋葬虫科在加拿大是一个多样化的科，但在BOLD中代表性明显不足。在加拿大，拟步甲科、小葬甲科、长蠹科、缩腿甲科和沼甲科等科在分类学上鲜为人知，在我们的BOLD数据集中，这些科的BINs数量比记录的物种数量多得多。
