Checklist of Canadian Nematodes

The nematode collection was begun by A.D. Baker in 1943 and is the primary depository for Canadian nematodes excluding parasites of humans and other animals. There are nearly 30,000 slides and 5000 vials of over 88,000 roundworm specimens in the Canadian National Collection of Insects, Arachnids, and Nematodes (CNC), including approximately 5000 primary and secondary types of nearly 400 species. The nematode type catalogue, as of 1985 (from Journal of Nematology 17: 220–234) is available online.

This checklist is based on a subset of CNC’s nematode (roundworm) accessions from Canada’s provinces and territories. This checklist is not exhaustive; nematodes regulated by the Canadian Food Inspection Agency are purposefully removed from this compilation. Scientific names were cross-referenced against valid and accepted names indicated in Nemys, the World Database of Nematodes.
