Synopsis of adventive species of Coleoptera (Insecta) recorded from Canada. Part 5: Chrysomeloidea (Cerambycidae, Chrysomelidae, and Megalopodidae)

Abstract

Structure and convention. This review is based largely on the published literature and on information associated with identified specimens mainly in Canadian collections. The arrangement of the species and classification follows that used by Bousquet et al. (2013). We use the term 'adventive species' for those that arrived in Canada from other countries either through natural dispersal or through inadvertent or deliberate human action during the period since initial arrival of European colonists (Wheeler and Hoebeke 2009, 2017). We do not include coverage of native Canadian species transported to new provinces and territories within Canada. We also do not include arrival of native United States species into Canada. Images. Images were taken using an image processing system (Nikon SMZ-U stereo-microscope with a ProgRes 3012 digital camera or Nikon SMZ1500 stereoscopic microscope fitted with a Nikon Digit-like camera DXM1200F) and compiled using Adobe Photoshop software. Distribution. Each species is cited with its currently known distribution in Canada and the USA. Data for distribution maps were extracted from specimens in collections, from literature records and, in a few cases, from authoritatively identified images from the BugGuide website (www.bugguide.net). Geographic coordinates were standardized using NAD83 datum, and maps projected onto a Lambert Conic Conformal using ESRI ArcMap version 10 for Windows.

DNA barcodes reveal 63 overlooked species of Canadian beetles (Insecta, Coleoptera)

“…Species that are adapted to disturbed or ruderal habitats are more likely to be accidentally transported through human activities than species that require nonsynanthropic habitats (Lockwood et al 2013). Many of the adventive beetle species established in North America are strongly synanthropic and occur mainly in human-disturbed habitats and settlements (Klimaszewski et al 2010(Klimaszewski et al , 2012. Not surprisingly, most of the new adventive species we report here were found mainly or exclusively in Southern Ontario, which is Canada's most densely populated and biodiverse region, and in the Greater Vancouver area, the third largest metropolitan area in Canada and home to the busiest port in the country (also with high native insect diversity).…”

“…Due to taxonomic confusion until the 1970s, reports of Pseudomedon obscurellus and P. obsoletus from regions outside of the Palaearctic need re-confirmation (Assing 2009, Klimaszewski et al 2013. The record of P. obsoletus from British Columbia from Hatch (1957) is doubtful and likely refers to P. obscurellus as it was described as being partly dark rufous, a color more typically associated with this species (Assing 2012).…”

“…Canada, and Washington and Oregon in the United States (Klimaszewski et al 2015). Orthoperus corticalis is darker and slightly larger than O. atomus, with stronger punctation on the pronotum and elytral base and denser and more strongly impressed microsculpture (Bowestead 1999).…”

“…A series of publications by Klimaszewski et al (2010Klimaszewski et al ( , 2012Klimaszewski et al ( , 2013Klimaszewski et al ( , 2015Klimaszewski et al ( , 2017 provides both diagnostic features and overviews of the ecology and known North American distribution of these species. While Europe has been and still is a major source of these species because of the intensive trade and ship traffic across the Atlantic, the proportion of Asian species has recently increased as a consequence of increased trade with this region (Klimaszewski et al 2012). The establishment of Palaearctic species in North America is likely facilitated by the climatic similarity of the regions (Klimaszewski et al 2013).…”
